Full Stack Software Engineer

## About the Role We're looking for a full stack engineer who can hit the ground running and make an immediate impact. Crucially, you're genuinely AI-native: you use AI coding tools and agentic workflows as a core part of how you work. You'll ship across the full stack, crafting clean React UIs, building reliable Node.js and Python services, and deploying to AWS. You'll own features end-to-end alongside a small, strong engineering team, and you'll have real influence over how the product evolves. This position operates on a hybrid work model with 3 days per week in our Cambridge office. ## The Work You'll Do - Build responsive, modular UIs in React and TypeScript that make complex emissions data feel simple and intuitive. - Develop and maintain backend services in Node.js, designing clean APIs and working with cloud-native AWS infrastructure. - Use AI coding tools and agentic coding workflows as core parts of your daily development practice. - Ship features end-to-end: from picking up a product brief to deploying to production via our CI/CD pipelines. - Contribute to architectural decisions, code reviews, and the kind of high-quality engineering culture that makes everyone better. ## Requirements ### The Minimum Qualifications You'll Need - 1 – 3 years of professional experience building full stack web applications. - Strong proficiency with React and TypeScript on the front end. - Solid Node.js skills for server-side development and API design. - Hands-on experience deploying and working with AWS infrastructure. - Real, daily use of AI coding assistants and agentic coding tools. - A project portfolio or examples you're proud of. - The ability to work independently, communicate clearly, and make good trade-offs under pressure. ### Preferred Qualifications - Experience with GraphQL, Terraform, or CI/CD tooling. - Background in early-stage startups or high-growth product teams. - Degree in Computer Science or a related field (not required, work speaks louder). ## What We Offer ### Compensations & Benefits - £45,000 - £65,000 base pay dependent on your skills, qualifications and experience. - Year-end performance bonus. - 25 days annual leave. - Competitive stock option plan so you can become a co-owner in the business. - Company pension with NEST. - Leading private health insurance with WPA (the only Which? Recommended Provider for Private Medical Insurance). - Cycle to work scheme. ### Work Environment - A hybrid work model that fosters both teamwork and individual flexibility. - Remote working allowance (2 weeks per year). - Work from Neutreeno HQ at the Cambridge Institute for Sustainability Leadership, recognised by the FT as one of Europe's leading startup hubs. - Great on-site amenities (unlimited free coffee, weekly events with global sustainability leaders...). ### Culture & Growth - A flat, fast-growing team (200%+ YoY growth) from diverse backgrounds that recently closed a $5M seed round. - An open-minded culture with a flat hierarchy and everyone vectoring in the same direction and where ideas and ownership matter. - The chance to work alongside world-class climate scientists and engineers on one of the most important problems of our time. ## How to Apply To apply, send your CV and a cover letter here covering two things: how AI tooling actually features in your day-to-day development work, and what's drawing you to Neutreeno specifically. Neutreeno is an equal opportunity employer committed to creating an inclusive workplace.
