Backend Engineer (Fullstack) — Systems-first, but you don't stop there! Are you a backend engineer who thinks in systems and in products? Do you obsess over clean architecture, scalable APIs, and solid data models, but care deeply about what those systems actually enable for the person using them? Have you got the battle scars of building something from scratch, whether as a founder, a founding engineer, or the first person in the room when the codebase was blank? A high-growth product team inside a fast-moving fintech is looking for a Backend-strong Product Engineer to own the systems powering a new product line and everything behind it when needed. This team operates like a startup within a company. So lean, fast, and building MVPs that matter. The other engineer on the team handles the frontend. You're the one who makes sure everything behind it is fast, reliable, and ready to scale. They won't hand you a spec. They'll expect you to help write it. What you'll do ▸ Own the systems: you're the person asking "but how does this actually work at scale?" in every product discussion, and then building the answer. Backend-first thinking, fullstack execution when it counts. ▸ Build fast and iterate: MVPs in weeks, not quarters. This team expects you to move quickly and make good decisions under ambiguity. ▸ Shape the product direction: they don't want someone who just builds what they're told. They want someone who challenges, scopes, and argues for the right thing to build. ▸ Step into the frontend when the product needs it: you're not a back-of-house-only person. You can ship a UI, contribute to the product experience, and think about the end user — you just naturally start from the system and work outward. The team This is a moonshot team. A small group operating separately from the day-to-day, with the remit and the freedom to build something genuinely new. The successful candidate will report directly to the head of the organisation. No committee, no lengthy approval chain. Just strong people solving hard problems fast. The role is in-office in London, 5 days a week. This team works hard so if you want a 9-to-5, this isn't it. If you want to build something you're proud of, it might be exactly right. What they're looking for 🏗️ Ex-founder, co-founder, or first-10 engineer at a startup — this is non-negotiable. They need people who know what it feels like to own something. ⚙️ Backend-strong, with genuine fullstack capability. You're at your best in the systems layer, but you're not precious about it. APIs, data models, infrastructure — that's your home ground, but you can venture forward when you need to. Language? Bring what you're great at. ⏱️ 5+ years of strong engineering experience, with evidence of shipping things that perform under pressure. 💬 Opinionated about product and able to explain not just what was built, but why, and that reasoning holds up under pressure. 🤖 Uses AI dev tools daily and can articulate specifically how it changes their output. 📈 Ambitious, so you are someone who wants to see their work move metrics, not sit in a backlog. What they offer 💰 £100,000 – £160,000 base salary 🤝 Meaningful equity, a genuine stake in what you're building 🏦 Pension contributions 🎯 Direct access to leadership and genuine influence on the product from day one 🚀 The chance to build something from zero in a high-growth fintech with the resources to back it

Company A high-growth construction technology business is hiring a Robotics Software Engineer to support the development and deployment of robotic, automated manufacturing systems – transforming how homes are built through hardware and software. Currently, they are developing the next generation fleet of their platform. Construction is one of the least digitised industries globally, facing major challenges across cost, labour, and delivery. This team is solving that by combining robotics, mechanical engineering, and automation to enable faster, more efficient, and scalable production environments. Responsibilities • Partner with the existing team to meet their launch date of September., • Develop robotics software, utilising a deep understanding of C++ and Python., • Operate in a ROS based architecture to build new features and enhance reliability., • Help identify and handle edge cases before the system ships to clients., • Test and validate software changes on physical hardware in the workshop., • Collaborate closely with the engineering team on priorities as they shift. Requirements • Background in Mechanical Engineering, Mechatronics, or Robotics., • Exposure to robotics, automation, or electromechanical systems., • Direct experience in mechanical engineering and real-world hardware., • Comfortable working hands-on with tools, systems, and physical components. What Stands Out • Internships or placements completed during university, • Experience working with mechanical, electrical, or pneumatic systems, • Hands-on exposure to robotics systems, • CAD experience and ability to work from or produce technical designs, • Personal projects, builds, or engineering work outside of formal environments, • Startup experience or evidence of working in fast-paced, ambiguous settings

About Our Client We're representing a company on a mission to redefine how modern distributed systems are tested and released. Their platform is trusted by engineering teams who demand rock-solid reliability, scalable performance, and deep technical visibility — and it exists because developers deserve something better than what's out there. If you've ever lived through a production outage, had a brutal on-call week, or watched a release slip by weeks because of one killer bug — you'll understand exactly why our client built what they built. If you're passionate about developer-first products, system resilience, and correctness, keep reading. The Role Our client isn't looking for a typical SE. They want an unconventional thinker — someone who gets genuinely energized by breaking things, thrives on chaos, and has the technical chops to deploy a sophisticated testing platform against real-world software and make it sing. You'll split your time between hands-on POC work, customer-facing technical conversations, and thought leadership around a testing paradigm that most engineering teams haven't encountered yet. You'll be the person in the room who actually understands what's happening under the hood — and can make a skeptical senior engineer a believer. What you'll do: • Execute POC engagements that demonstrate real product value to prospective customers, • Lead customer workshops on Property-Based Testing (PBT) and related methodologies, • Support the sales team with technical qualification and consultation, • Find bugs. Break open source software. Make a point of it., • Build, maintain, and deliver product demos that land with technical audiences, • Guide customers and prospects on platform adoption and testing best practices, • Participate in new customer onboarding and early-stage success, • Highly technical — and more importantly, technically curious, • Easily bored; you need new problems to stay engaged, • A natural communicator who can translate complexity for both engineers and executives, • Comfortable under pressure and in tight timelines, • Professional enough for enterprise clients, flexible enough for a fast-moving startup, • Hands-on experience building and running automated tests (integration, end-to-end), • Containerization: Docker, Kubernetes, • Object-oriented programming fundamentals, • Linux-based operating systems, • Scripting: Bash/Shell, Python, or JavaScript, • Data querying: SQL, NoSQL, or equivalent This role requires some travel — client sites, conferences, and occasional visits to our client's HQ. If that's your thing, all the better. Why It's Worth a Look Most SE roles are demo-and-support. This one is different. Our client is building a new category, and the SE who joins now will have outsized influence on how that story gets told technically — and how customers succeed with a platform that genuinely does something new.

You’re a senior engineer who gets restless when your work feels abstract. You want to see your code in the real world, nudging health outcomes, not just engagement metrics. You’re happiest when you own problems end-to-end, from fuzzy product idea to shipped feature, and you don’t need a 20-page spec to get moving. You care about system design and code quality, but you care just as much about whether what you’re building actually helps people. You’re product-minded: you ask “what problem are we solving for the patient?” before you ask “what stack are we using?”. You’re comfortable in TypeScript and at home in React / React Native / Node (or similar), and you like working across the stack rather than being boxed into a narrow layer. You enjoy fast feedback loops, shipping in days, not weeks, and iterating based on data and real-world usage. You’re AI‑curious (or AI‑obsessed), already using LLMs in your workflow, and itching to push them deeper into the product itself. You thrive in senior, flat teams where responsibility is the default, not the reward. You’re comfortable making decisions with imperfect information, debating trade-offs with peers, and owning production systems when it really matters. You don’t want to just advise; you want to build. If that sounds like you, there’s a London‑based healthtech scale‑up you’ll probably love. They’re building a single React Native/TypeScript platform that powers GLP‑1 weight loss journeys across the UK and US markets, aiming to reduce the burden of obesity, diabetes, and cardiovascular disease at scale. You’d lead complex feature work on a high-traffic app, integrate AI/LLM capabilities (including conversational experiences) to support behaviour change alongside medication, and help shape the engineering culture in a senior-heavy, high-agency team. FAQ's Salary: Up to £130 000 Location: 4 days a week in a Warren Street office If you’re a senior engineer who wants to ship serious software with real-world health impact, drop me an email () with “Tipping The Scales” in the subject line. Include your CV if you have it ready or just your LinkedIn profile and a couple of lines that you wrote yourself as to why you think this could be your next role. All applications received as above will be reviewed by a human (me) and will get feedback. LinkedIn applications may not all be reviewed due to volume and lack of relevance.
