What if you could use AI to fix a huge, real world problem? I'm not talking about another abstract SaaS product, but something that impacts real buildings, real people, and real operations every single day? This is a genuinely rare, potentially life changing opportunity to become the first engineering hire at a company with the ambition and backing to become a future tech unicorn. The company was founded recently by two exceptionally strong founders who have a history of building, scaling, and selling businesses. They’ve already raised $10m+ in funding and have a clear, aggressive plan to deploy that capital to accelerate growth quickly, so you’ll be joining at the very start, but with serious momentum behind it. They’re tackling a huge, real world problem in a £100bn+ market. As we know, every hospital, school, pub etc must meet strict safety and compliance requirements. Despite how critical this is, the industry is still largely run on manual, outdated processes: spreadsheets, PDFs, and weeks or even months spent writing reports and documentation. It’s inefficient, frustrating, and ripe for change. That’s exactly what this company has cracked. They’re building a fully AI native platform that automates the admin and paperwork that specialist engineers hate doing, so those engineers can focus actually solving real problems. The result is massive gains in productivity, better margins and software that operators genuinely want to use. What makes this especially compelling is the growth strategy. These aren't just selling software and hoping for adoption, the company acquires profitable, real world service businesses and brings them straight onto their AI platform. That means immediate users, real operational data and fast feedback you’ll see the impact of your work in the real world, almost immediately.. As Founding Engineer / Tech Lead, you’ll get stuck in from day one, with real ownership and influence. You’ll design and build the core platform, automate messy real world workflows, and shape how AI is actually used inside operational businesses. You’ll also be backed to grow your own team, with a clear path to Head of Engineering / CTO, and meaningful, potentially life changing equity. This won’t be for everyone, there will be long nights and hard problems to solve but for the right person, the upside and ownership are exceptional. If you enjoy building from scratch, want autonomy and influence, and like the idea of applying AI to the physical world, not just dashboards, this is a rare chance to help define a company at the very beginning. Everything is confidential at this stage. If you’re open to hearing more, apply below or email .

Founding Growth Lead — Build the Future of AI‑Powered Music Creation - 80K Here at Venchr, we’re working with one of the most exciting creative‑tech teams in London — a small, sharp group building the next wave of AI‑driven music creation. They’re growing fast, backed by serious investors, and already pulling in a huge community of creators, hobbyists and pros who are making studio‑quality music in seconds. It’s fresh, it’s fast, and it’s genuinely pushing culture forward. The team works with high ownership and high speed. No ego, no drama — just a group of people who care about what they’re building and want to make something that lasts. If you want to work somewhere where your ideas actually matter and the pace keeps you switched on, this is that environment. As the Founding Growth Lead, you’re the person who builds and runs the entire growth engine.

You’ll probably be someone who’s already run paid campaigns hands‑on (not through agencies), someone who understands creators and feels comfortable experimenting with content, formats and on‑camera work when needed. You know how distribution actually works because you’ve done it , whether that’s building an audience, running a channel, or producing content that consistently lands. If you’re into music or have even made some yourself, even better. You think clearly, work fast, learn quickly and don’t take yourself too seriously. And you use AI tools naturally, not because they’re trendy but because they help you build smarter. Salary for this role ranges from £50k–£80k, plus significant equity, and you’ll be working full‑time from their central London office with a small, talented team. It’s the kind of job where you’ll actually see the impact of your work every week and where you get to help define the growth engine for something genuinely creative and meaningful.

Founding Engineer Basics • Up to £100k + generous, early-hire equity., • Impactful mission: your work will directly improve the lives of vulnerable children., • Ownership and responsibility: lead engineering and shape the product from the ground up., • Work closely with the founder and leadership on a daily basis., • Based in London, 2-3 days a week in-office. What are we building, and why? • Social care is a £96bn sector, completely broken by administrative burden and outdated processes. This system is under severe pressure and it’s failing the vulnerable people that need it most, leaving them in unstable and unsafe situations. We can help fix it., • We’re starting where the need is most urgent: children’s care. Today, fragmented tools and manual processes slow decision-making and increase the risk of unsuitable placements. The consequences are severe: children living in illegal or temporary placements, being moved repeatedly, and not finding the stability they need. At the same time, care workers are overwhelmed by admin and unable to focus on what matters most: the people they support., • Elyndra exists to remove this friction. We build software that automates unnecessary labour and accelerates decision-making - without taking control away from professionals - so the system can operate at the pace children need. Who are we? • We’re currently a small, talent-dense team (including Y-Combinator exited founders), looking for our next superstar., • Our founder, Marcus, brings deep sector expertise through direct family experience in care settings and has seen firsthand how better technology can reduce pressure on teams and materially improve outcomes for children., • We’re backed by leading VCs and angels and work with a strategic PE partner that owns over 160 care homes - giving us both the mandate and a clear route to scale impact across the sector. The role As Founding Engineer, you’ll lead the technical development of our AI-first product, ensuring we build something our customers love. What does the role involve? • Own product development, architecture and technical roadmap. Make key decisions that influence the business., • Decide how we build things - balancing speed of iteration with long-term stability., • Understand our users in-depth. Proactively think about their needs and turn them into outstanding products., • Design intuitive UIs that care workers can use with confidence - visualizing complex insights in a way that is clear to non-technical users. What does the ideal hire look like? • You’re a product-first engineer. You care about building something that provides value to users, not just elegant code., • You’re full stack: as you’ll be building end-to-end, you need to be comfortable working across both backend and frontend., • You have experience integrating LLM services into applications, and ensuring high-quality, reliable outcomes., • You can move from fast, scrappy prototyping to scalable, architectural work. You understand when to apply which., • You have experience building secure cloud-based applications., • You have experience implementing security best practices for handling sensitive data. Ideally, you can demonstrate having implemented GDPR and security compliance in technical systems., • You’ve worked at early-stage startups before, or you are a tinkerer that has built products on the side for years. Bonus points if you have experience in social care or healthcare. Our current tech stack is: Python, React, PostgreSQL, GitHub, Docker. This isn’t dogmatic - you’ll have the autonomy to evolve the stack where it makes sense. You’ll be a great fit if: • You thrive with true autonomy, ownership and responsibility. You’re a high-agency problem solver that understands problems fast., • You want to shape a business from the ground up., • You’re excited by the opportunity to have a real impact on a large but underserved sector., • You’re a team player - you communicate clearly and make the people around you better. You’re able to explain technical concepts to non-technical people. The role isn’t for you if: • You need tightly defined daily tasks, require very clear lanes and don’t enjoy working in a fast-paced environment with loosely defined requirements., • You are not comfortable with change., • You don’t know how to be scrappy. Perks and benefits: • Career opportunity - a competitive salary and meaningful equity in a high-growth start-up, with the chance to lead and shape the future of a category-defining product., • Talent - we’re a small, high-caliber team that cares deeply about the mission., • Impact - build advanced tech that has a real impact on vulnerable people., • Valued on outcome, not hours - we work hybrid and with flexible hours. We focus on working in the ways that enable us to deliver our best., • Holidays - 25 days plus bank holidays. Use up to 5 flexible bank holidays on days that are most meaningful to you., • Professional development - budget for tools, courses, conferences and more. Your growth is our growth., • Pension scheme - 3% employer contribution + 5% employee contributions. Elyndra is an equal opportunity employer - In line with the Equality Act 2010, should you require any reasonable adjustments to the application process, please let us know via the form and we will get back to you to discuss your requirements as necessary. All applicants must have the right to work in the UK and will be required to pass an Enhanced DBS check due to access to vulnerable persons’ data.
