You'll be expected to take more technical leadership than managerial responsibilities, promoting better engineering practice, driving technology improvements and leading from a strong hands-on perspective. This is a web-based reporting platform written in Python and Django, and your decisions around the technical direction will be critical in the future success of the business and how they continue to deliver to their clients. If the opportunity to take responsibility for new projects, from research through to deployment, excites you then this could be a great role to explore. You'll be working on the improvement of their platform, leading feature development, liaising with stakeholders and Product teams internally, working through the entire life cycle.

Location: London (hybrid) Level: Director Reporting to: VP of Engineering The company This is a well-funded, fast-growing B2B SaaS company that's become one of the most talked-about in its space. They've hit unicorn status and are now in the middle of a significant scaling phase — the engineering org is ~50 people today and is expected to grow to 150+ over the next 12 months. The product is used by some of the world's fastest-growing companies. The team is distributed across the UK and Europe, with a strong technical bar and a no-nonsense engineering culture. People here came from Google, Meta, Vercel, and high-growth scaleups. The VP of Engineering spent 9+ years at Google managing infrastructure teams at significant scale before joining at an early stage. This is not a corporate environment. Founders are hands-on, technical, and have high standards. The people who thrive here have opinions, make decisions, and lead from the front. The role You'll be joining as one of two Engineering Directors, sitting between the VP of Engineering and a layer of engineering managers who each lead autonomous product squads. You'll own a significant portion of the engineering organisation and be accountable for how it performs, scales, and grows. This is a player-coach role in the truest sense of leadership — not hands-on coding, but close enough to the technical work that you can hold your own in a systems design conversation, challenge architectural decisions, and earn the respect of strong engineers. What you'll be doing: • Managing a set of engineering managers and senior ICs, acting as their line manager, coach, and technical sounding board, • Owning the health and output of multiple product squads — delivery, quality, morale, and hiring, • Partnering with the VP of Engineering on org design, technical strategy, and how engineering scales from here, • Driving hiring across your org — you'll be building something meaningful over the next 12 months, • Feeding into cross-functional decisions alongside product, design, and go-to-market leadership, • Being the person who makes the call when things are ambiguous, moves fast when speed matters, and is comfortable having hard conversations What we're looking for Must-haves: • Experience managing engineering managers (not just individual contributors) — you've operated a layer of abstraction above the squads, • A background that combines time at a well-engineered large company and time at a high-growth B2B SaaS scaleup — you understand both how great engineering is built and what it takes to ship fast with limited resources, • The technical depth to do a credible systems design conversation — you don't need to write production code but you need to understand the tradeoffs engineers are making, • Experience in the 50–200 engineer range — you've either been through a scaling journey like this or are close enough to it that you understand what breaks and why, • Comfortable with ambiguity, fast-changing priorities, and a culture where the people above you are also deeply capable Strong signals: • B2B SaaS domain experience — RevOps, developer tooling, or anything close to the product surface, • You've hired well at pace — you know what great looks like and you can move quickly to close, • You've let people go when it was the right thing to do, • You've worked in a distributed team and made it work, • You're the kind of person who's done their research before walking into a room Not a fit if: • You're looking for a quiet, process-heavy environment, • Your default mode is "let me set up a committee", • You describe your leadership style primarily as "servant leader" and leave it there, • You haven't been close to the technical work in several years The interview process • Track record conversation (45 min, remote), • Incident response / technical leadership (45 min, remote) Compensation Competitive base salary, meaningful equity, and benefits. Range discussed on first conversation.

About Amplifying Life We're a London-based light research, education, and hardware company building devices that put photobiomodulation science to work. In short: • Foreword to our book The Sun Inside You by Prof. Michael R. Hamblin PhD — the scientist who named the field (600+ peer-reviewed publications), now on our scientific advisory board, • Members of the Royal Society of Medicine, Microsoft for Startups, Barclays Eagle Labs, and Capital Enterprise, • Founded by an engineer with 20+ years in embedded electronics; patents cited by Microsoft, Google, Apple, Qualcomm, and Cisco The role Earn up to £12,000 across your first 10 placements — £1,000 guaranteed base + up to ~£11,000 commission. We are hiring field sales representatives to place photobiomodulation (red-light therapy) devices into retail locations across London — starting with Central London. This is a fixed-term contract for self-employed professionals. Guaranteed base payment of up to £1,000 for documented work delivered, plus a substantial commission upside of up to ~£11,000 on top if the first 10 free-trial placements land successfully — that's where the real money is. Neither the shops nor their customers pay upfront, so this isn't traditional "sell it for cash" selling. You're placing free trial units with receptive locations. If the trials work, the upside is real. Photobiomodulation is a global market estimated in the hundreds of millions to over a billion dollars, growing fast. We are not selling into a dead category — we are early in a rising one. What you will be doing · Researching target locations, identifying the right owner or manager, and reaching out by phone or email · Booking meetings to explain what we do, sign a simple agreement, place the free trial devices and materials on site, and give the location's staff a short first briefing on how to offer the product to their customers · Coming back to check in, and keep the relationship warm This is not desk work. This is not tele-sales. This is real, face-to-face relationship-building with business owners across one of the best cities in the world. What we are looking for · You are in London and can move around Central London on foot and public transport · You are comfortable picking up the phone to someone you have never met, introducing yourself, and booking a meeting · You can explain something technical in plain English without sounding like a brochure · You are resilient — not every conversation will go your way, and that is normal in sales · You believe in the project and are here to build, not just to bill us for every fifteen minutes Useful but not required: prior sales experience (beauty, medical devices, premium retail, consumer electronics, FMCG), knowledge of photobiomodulation or red-light therapy, a driving licence, existing relationships with London retail locations. We are open to candidates at any level of experience — what matters is that you can see the upside and back yourself to earn it. The offer Guaranteed base pay up to £1,000 — for documented work, no outcome dependency: · £200 on delivery of a verified log of 50 owner/manager contacts at target businesses · £40 per attended in-person meeting, pro-rata up to 20 meetings (max £800) On top of the base — where the real money sits: · Up to ~£11,000 commission if the first 10 free-trial placements land and convert as planned · Territory expansion — if the first territory performs, you earn the option to run additional London areas under the same structure · Direct line to the founder. You work directly with Asim, not through three layers of management · Our devices are built on technology grounded in over 10,000 peer-reviewed studies in photobiomodulation, plus research directly relevant to our specific approach. Comparable products are already selling well in the market — we are just making it more accessible. · Room to grow. This role can become something much bigger for the right person How to apply Apply through official job post. We read every application personally. If we think there's a fit, we'll be in touch.

We’re seeking an exceptional Head of Engineering / Engineering Manager to partner closely with our CTO and lead the next stage of our engineering organisation. We want a deeply technical leader who still loves to build, leads from the front, and thrives in high-velocity, high-ownership environments. Your mission: build the fastest engineering team on the planet. Who you are: You’re a top-tier engineer with proven leadership experience in fast-moving startups or scaleups. You’re comfortable making imperfect decisions quickly, you’ve built products under pressure, and you know that momentum beats perfection. You might be: • A seasoned engineer who has already stepped into an Head of Engineering / Engineering Manager role at a venture-backed startup, • An ex-founder who has built and shipped products under real pressure, • A startup tech lead who thrives on ownership and bold decisions, • A pragmatic builder who values time-to-value over “the right way” What makes you perfect for this role: • Engineering leadership: You’ve coached and unblocked engineers in high-velocity, high-pressure environments., • Deep technical expertise: You have strong architecture instincts and solid security knowledge, but you’ll cut through complexity to keep shipping., • Startup operator mindset: You’ve taken products from 0→1 or through hyper-growth and know how to build systems that evolve with the company., • Velocity obsession: You believe iteration > perfection, and your instinct is always to get value in front of users as fast as possible., • AI-first: You’re bullish on AI, vibe-coding daily, and always looking for ways to push velocity through AI-assisted workflows., • DevX focus: You obsess over developer experience because you know great tooling = more speed., • Execution focus: Monitoring, observability, and performance aren’t “nice to haves”, they’re how you ship fast without breaking trust. What you'll do • Set the bar for engineering velocity: coaching, mentoring, and unblocking the team every day, • Make architectural and security calls fast, balancing speed with long-term resilience, • Build and own best-in-class developer experience - tooling and workflows that eliminate drag, • Monitor and protect reliability and SLAs, while still moving at startup speed, • Establish a culture where iteration is celebrated and perfectionism is challenged How we work at Lightdash • We build in public. Open source means moving fast with shared context., • We challenge problems, not people. No blame, just solutions., • We’re highly collaborative. Independent, but we win as a team (and with our community)., • We bias hard toward impact. We’d rather ship the wrong thing quickly and learn, than waste weeks polishing what nobody needs. Our tech stack: • Primary: TypeScript, React, Node, SQL, • Frameworks: Express, React-hooks, Redux, RTK, Mantine ⚡ We’re deliberately looking for ambitious leaders from startups and high-growth companies. If you want predictability, long roadmaps, and “the right way” over speed, this isn’t the role for you. 👉 Research shows that women and underrepresented groups often don’t apply unless they meet 100% of the requirements. Even if you don’t tick every box, if you have startup experience and a hunger for velocity, we’d love to hear from you.

To apply, please send the following to • Your resume / CV, • A short blurb introducing yourself and explaining why you are a good fit for the Hive, and confirming which location your're applying to (New York or London). Keep it short & real, no need for a fancy cover letter!, • Links to anything cool you’ve built with AI for work, school, or even just on your own time Position Overview The AI Hive is TowerBrook’s new fellowship for applied AI builders. This is not an analyst program and it is not a consulting role. Fellows do not produce slides about what AI could do. Fellows train intensively inside TowerBrook for six months, with the opportunity to progress into a twelve-month embed inside one of our portfolio companies as an Applied AI Engineer, working directly with CEOs and operating teams to ship AI-native solutions that move real numbers. The fellowship runs in two phases. In Phase 1 (six months), fellows are based at TowerBrook in New York or London, training with leading external AI partners and shipping high-priority internal projects across the firm. Fellows who excel in Phase 1 are considered for Phase 2 (twelve months): a full-time, onsite embed inside a TowerBrook portfolio company, working in person alongside the management team and reporting to the CEO, CTO, or Head of AI, and delivering milestone-based work with measured business outcomes. Fellows in this first cohort will have a unique opportunity to shape how TowerBrook builds and deploys AI talent across the portfolio Responsibilities Phase 1. Inside TowerBrook (Months 1 to 6) • Complete a three-week intensive training program with a leading AI-native training partner, covering prompt engineering, agent architecture, Claude Code and other coding assistants, workflow automation (n8n, Lovable), Python, and enterprise AI governance., • Pair with internal devs and senior engineers from best-in-class applied AI firms on live TowerBrook projects, shipping working prototypes within the first six weeks., • Lead at least two internal builds with named senior sponsors as business owners. Projects may span front, middle, or back office (investment teams, operations, finance, IR, compliance, knowledge management) depending on firm priority. Deliver shipped output, not recommendations., • Contribute to the shared Hive knowledge base (reusable agents, templates, playbooks) that compounds across future cohorts. Phase 2. Portfolio Company Assignment (Months 7 to 18) • Match into a portfolio company across TowerBrook verticals based on fit, and relocate as needed to work onsite at the company’s primary office for the duration of the twelve-month embed. Matching is jointly led by the Program Lead, the senior program sponsor, and TowerBrook’s Technology Operating Partners., • Run a four-week diagnostic sprint: map workflows, validate pain points, and produce a twelve-month build roadmap signed off by the company CEO and the TCP sponsor., • Execute three to five milestone-based build sprints of eight to twelve weeks, each delivering measured output (hours saved, revenue uplift, cost reduction, new capability shipped)., • Report directly to the company CEO, CTO, or Head of AI, while retaining ongoing connectivity to TowerBrook for the duration of the engagement., • Attend monthly Hive-wide cross-pollination sessions with other fellows and coordinators. Document learnings for the Hive knowledge base., • At the close of the twelve-month deployment, transition into one of four paths: a full-time role at the portfolio company, redeployment to a second company, a role at TowerBrook, or release into the TCP alumni network. Professional Qualifications & Experience • One to three years of post-university experience in a builder role. We read “builder” broadly: software engineering, data, product, operations with automation exposure, quantitative research, consulting with hands-on implementation, or early-stage startups. Candidates with fewer than one year or more than three years of experience are out of scope for the pilot cohort., • A technical or quantitative undergraduate background is welcome: computer science, engineering, physics, applied mathematics, statistics, computational biology, industrial engineering, operations research, information systems, or quantitative economics. We will also consider non-technical majors with visible builder evidence such as a GitHub portfolio, shipped side projects, or published technical writing., • Fluency with modern AI tools. You already use Claude or ChatGPT daily as a core part of your workflow, not as a novelty., • Working proficiency in Python or another scripting language is a plus — enough to prototype end-to-end without supervision is ideal, but not required. Formal ML engineering or data science experience is not required and is not what we are optimizing for., • Demonstrated evidence of shipped work outside a structured environment: a side project, an automation built at a previous role that nobody asked for, a product used by real users, or published writing with an audience. What you built matters more than where you built it., • Right to work in the United States (for New York candidates) or the United Kingdom (for London candidates) is preferred. Visa support may be available for exceptional candidates. Personal Qualifications • Stakeholder presence. At ease working with a company CEO or a TowerBrook partner, approaching business problems with curiosity and humility., • AI-native instinct. You reach for AI tools naturally during ideation and problem solving., • Builder disposition and bias for action.

About Loctax: Loctax is a tax technology company. We build software for tax professionals at large multinationals and advisory firms — helping them with tax research, compliance, risk and governance management across all the jurisdictions they operate in. Founded in 2020, Loctax was acquired by Tax Systems in 2025 and is now part of the UK’s leading corporate tax software group, trusted by thousands of tax and finance professionals. Together with Tax Systems, we are building the very first Tax Operating System — one AI-powered platform where global tax professionals can research, comply, and make decisions without switching between a dozen disconnected tools. This is an early and pivotal moment in that journey. The Opportunity: This is not a role for someone who needs a fully paved road. You will work directly with our Co-founder, GTM Engineer, BDRs, Sales Director, and Account Executives — and you will own pipeline generation from first touch through to qualified meeting. The BDR team is small and there's no fully built playbook that can be handed to you. The upside is real, and so is the expectation. You will have direct influence on how we build our market presence from the ground up. Your work is visible, your impact is immediate, and the role grows with you. There are plenty of opportunities to step into an AE role within 12 months after starting, or switch to something else if you’d like. This role suits someone who thrives in incomplete information, makes sharp decisions with what they have, and consistently finds a way to overachieve — not because they were told to, but because that is simply how they operate. What You’ll Do: Prospecting & Lead Generation: • Build and work a targeted account list of multinational companies across key European markets., • Run outbound sequences across email, LinkedIn, and phone — personalised to the prospect, not templated., • Follow up on inbound leads and event contacts quickly and with purpose., • Run discovery calls to qualify opportunities and understand what is actually driving the prospect’s interest., • Get in front of senior buyers — Head of Tax, VP Tax, CFO — and earn their attention with sharp, relevant outreach., • Keep the CRM clean and your pipeline honest., • Hand off qualified opportunities to Account Executives with full context — not just a name and a company. Collaboration & Knowledge Sharing: • Share what you’re hearing from prospects with the product and customer success teams — we actually use that feedback., • Help position Loctax clearly and credibly in every prospect interaction. Continuous Learning & Process Improvement: • Get deep on the product and the space — you do not need a tax background, but you need to want to understand it., • Help build the sales playbook — you are joining early enough to shape how things are done., • Bring a positive, high-energy approach — things will not always be straightforward, and that is part of what makes it interesting. Requirements: Education & Experience: • 1+ years of BDR or SDR experience in B2B SaaS or professional services., • Comfortable in a metrics-driven environment — and more importantly, comfortable holding yourself to a higher standard than the metrics require., • A track record of overachievement — we want to know what drove it, not just that it happened. Skills & Attributes: • Strong written and verbal communication in English, • Comfortable making a high volume of cold calls and handling objections without losing your cool., • Confident across email, phone, and LinkedIn outreach., • High agency — you do not wait to be told what to do next. You identify the gap, form a view, and move., • Comfortable working with incomplete information — you make reasonable assumptions, act on them, and course-correct rather than waiting for perfect clarity., • Sharp enough to research a senior buyer, understand their business, and write outreach that is actually relevant to them., • Organised enough to run a full pipeline without being micromanaged. Bonus Skills: • Experience with AI-driven outreach and automation tools (Lemlist, n8n, Clay, Claude Code or similar)., • Experience doing detailed account research and qualification at scale using AI tools., • Familiarity with sales triggers and intent signals to sharpen outreach timing and lift conversion rates. Mindset & Motivation: • You hold yourself to a higher standard than the one set for you., • You are energised by ambiguity, not slowed down by it., • You want to understand the business, not just your quota — and you use that understanding to work smarter., • Excited by a role where the rules are still being written and your contributions shape how things are done. What we offer: • Annual leave - enhanced holiday plus any local public holidays., • Birthday day off., • Competitive salary., • Top tech gear., • Learning budget., • Bi-annual team offsites.

Founding Lead Product Designer The one who defines the product, not just the pixels. Not the one who waits for a brief. The one who identifies the right problem before anyone else has named it, designs the answer with conviction, and stays through shipping to make sure what went live is what was intended. Not the one who presents options. The one who has a point of view and can defend it. Not the one who hands off. The one who considers production drift a personal failure. You don't own a step in the process. You own the outcome. Healf is Europe's fastest-growing company. Number one on the FT1000, number one on the Sifted 100. From £1m to over £100m in under three years, with a small, talent-dense team and an electric culture with day one founder intensity. Now we’re aiming for £1bn in the next three. We curate the world’s best wellbeing brands across The Four Pillars™: EAT, MOVE, MIND, SLEEP. That’s the first chapter. The next chapter is harder and more interesting. We are moving from one market to many, from e-commerce to a technology platform, and from curating wellbeing to defining it. We are a health company, so we think we should act like one. At its fullest expression, Healf redefines what wellbeing means for tens of millions of people. Why this role is Healf Healf is building Wellbeing Intelligence. A product that learns what works, for whom, and why — from the behavioural data of over half a million customers. It will personalise wellbeing decisions, close the feedback loop between what people do and how they feel, and get smarter with every interaction. The most important question right now is not how to build it. It is “what should it be?” How does it earn trust with something as personal as your health? How does it tell you something true about your own body without creating anxiety? How does it feel like a companion rather than a dashboard? Those are design questions. The best answers will not come from competitive audits or component libraries. They will come from someone who understands people at the level of motivation and emotion, who can turn a fuzzy problem into a sharp product decision, and who can hold a vision together across months of building without losing the thread. This is the role that answers those questions. What you'll own → The product, from first principles. You will define what Wellbeing Intelligence looks and feels like as a lived experience. The mobile app. The core surfaces. The information architecture. The emotional register. Not by inheriting a brief, but by thinking from the user’s life inward. What does it feel like to be someone who wants to be well and doesn’t know where to start? Start there. Research it. Frame it. Design it. Defend it. → The design system, from scratch. Components, patterns, standards. You will build the foundation that every designer and engineer after you builds on. Decisions made in the first six months will hold at ten times the scale. Overbuild for a future that hasn’t arrived yet and you slow the company down. Underbuild and you create chaos. Get it right. → The language and culture of design at Healf. How does Healf feel as a digital experience? Clinical or warm? Minimal or rich? Expert or approachable? You will define the product language and defend it. You are building the design function. Every decision you make — the tools, the rituals, the relationship with engineering, how research happens, how feedback flows — becomes precedent. You are not joining a design culture. You are creating one. → A clear, opinionated product direction. You will have a view on what we build next. You will bring it to the table with evidence and argue for it. If you’ve only ever executed other people’s roadmaps, this is not the role for you. What you'll deliver in the first 12 months → A design language for Wellbeing Intelligence that is distinctive, coherent, and earns trust with users → A working design system that engineers build with and future designers will build on → User research that has actually changed what we built, not just validated what we had already decided → Users who describe the product experience in emotional terms, not functional ones → A clear, opinionated point of view on what the product should become next, backed by evidence from real usage → A design function that other people want to join Why you’re Healf You define problems, not just solutions. When handed a brief, your first instinct is to question whether it’s the right brief. You have strong opinions about what the user actually needs and the conviction to say so before a pixel is drawn. You have been the first. Maybe the first hire. Maybe a founder. Maybe the person at an early-stage company whose design decisions determined whether the product survived. You know what it feels like when there is no design system, no established patterns, no one to validate your decisions. You prefer it that way. You think in systems but you obsess over moments. The system creates consistency. The moments create feeling. An empty state that turns confusion into curiosity. An onboarding flow that makes someone feel understood before they’ve said a word. A notification that lands at the right moment and feels helpful rather than intrusive. These are not afterthoughts. They are the product. You have cross-functional depth. You have stayed through build. You have caught production drift. You have pushed back when the implementation missed the intent, and you have been in the room when engineering had to make a hard call. You understand the constraints without hiding behind them. You have strong opinions and you defend them without being precious. You push back on engineering when implementation drifts. You push back on product when the brief is wrong. You push back on yourself when the first version isn’t good enough. You are ambitious. Not about titles. About the work. You want to look back at this chapter and know that what you built changed how people think about their health. Show us → A product you led end-to-end where you can show the thinking, not just the screens. The problem framing, the decisions, the tradeoffs, the result, and what you would do differently. → Evidence you have worked at the zero-to-one stage: no design system, no established patterns, everything to define. What did you build and what did you decide? → A moment where your design changed what the company built, not just how it looked. Where you named a problem no one else had named and drove the solution. → Something that shows how you work with engineers. Not just hand-off artefacts. Evidence of real collaboration: the back-and-forth, the decisions made in implementation, the things that only became clear in code. → A point of view on what great health product design looks like and where most of it falls short. We want to see taste and opinion, not just craft. The deal We ask a great deal of the people who work here. We expect full ownership and a genuine commitment to give this chapter everything you have. In return, we will give you the same: everything we have, invested in your growth, your wellbeing, and the defining skills of the next decade. We have built the fastest-growing company in Europe with a team small enough that every person in it shapes the outcome. That is still true today. The next person we hire will change the trajectory of the company. If the most important work of your career is ahead of you, this is the place to do it. One question Send your CV, a link to your work, and your thoughts on this: How can the Healf app provide value to customers that they can't get elsewhere today? We want to see how you frame problems, not just how you solve them.
