You'll ship features that directly help the employees of our enterprise clients find the right support at the right time.We're using Claude Code throughout the SDLC, exploring how we evolve our development practices to leverage AI where it meaningfully helps. This is a great opportunity for someone who wants to deepen AI-assisted development skills in a team that's investing in them.What you'll do You'll ship features end-to-end. Break initiatives into deliverable slices, design solutions, write the code, and see them through testing, deployment and monitoring in production. You'll own the design for what you deliver. Choose pragmatic approaches that fit our existing architecture, write RFCs where appropriate, and make sensible trade-offs without needing extensive guidance. You'll keep things reliable. Respond to incidents and bugs in your team’s domain, improve observability where it's lacking, and uphold the security and performance commitments we make to clients. You'll improve what you touch. Tackle tech debt, refactor and upgrade dependencies where it unblocks delivery or reduces risk. You'll embed AI into how you deliver. Use Claude Code throughout your workflow - scoping, designing, coding, reviewing, documenting - and contribute to our collective learning by sharing what's working back to the team. 🌟 About You In the spirit of equity and continuous growth, we invite you to remove education from your CV. Qualifications are not a factor in our decision-making. However, some experience in the following is important for this position: You're ready to get a lot done. You’re a backend leaning Engineer, but comfortable moving across the full stack and have experience with TypeScript, React, GraphQL, Node.js and SQL. You enjoy problem solving from first principles, pick up new context fast, and ship impactful changes to customers regularly. You know what good looks like. You understand what it takes to build reliable products for clients. You build with performance, security and observability at the forefront rather than as follow-ups, and your code is simple, well-tested and easy for others to change. You're comfortable with ambiguity. You're happy tackling problems without a clear definition or obvious solution, and find the leanest viable path forward. You make deliberate trade-offs. You understand the impact of trade-off decisions made today. You choose lean over perfect when it's the right call, and you're explicit about what's being deferred and why. You’re comfortable with AI-assisted development practices. You use Claude Code (or similar tools) as a core part of how you develop features - applying curiosity and judgement to know where it accelerates and where it doesn't. Tip for candidates: If you’re unsure whether to apply – do. We know great people don't always tick every box.💚 Life at Unmind We believe wellbeing and performance go hand-in-hand – and we build our environment to support both.A few highlights:✅ Private medical for you & your family✅ Equity in Unmind✅ Generous gender-neutral parental leave✅ 25 days holiday + birthday + celebration days✅ Revive & Thrive Days – company-wide Friday off monthly✅ Flexible working + early Friday summers✅ Remote-first within the UK, with monthly in-person meet-ups and access to a London co-working space✅ Annual learning budget + learning leave✅ Free weekly therapy or coaching sessions✅ Wellbeing support via WellHub & BippitSee all benefits on our Careers Page →
