Senior Full Stack Software Engineer

Climate change is the defining business challenge of our time, and we're here to solve it. Most decarbonisation solutions count emissions but do nothing to reduce them. We've changed that.

We’re Neutreeno, an emissions-to-performance platform, born out of the University of Cambridge's Department of Engineering. We help companies with supply chains and production processes turn emissions data into operational insight, the kind that cuts costs, sharpens decisions, and unlocks genuine competitive advantage. For operations and finance, it's margin they can measure. For sustainability teams, it's progress they can prove. Same data, two audiences, one engine.

We’re a fast-moving team that values EQ just as much as IQ. Autonomy, high-ownership, speed and no-ego collaboration are at our core. We seek people who care deeply and are eager to work on solving problems bigger than themselves.

As a Senior Full Stack Software Engineer and key member of the Neutreeno team, you’ll be shipping great software, bringing strong engineering judgment, and making the team better through craft and collaboration.

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.

You also use AI coding tools and agentic workflows as a force-multiplier, and you’re actively curious about how they change what a small engineering team can achieve.

This position operates on a hybrid work model with 3 days per week in our Cambridge office. Fully remote arrangements may be considered for outstanding international candidates, provided there is sufficient overlap with UK working hours.

Build responsive, modular UIs in React and TypeScript that make complex emissions data feel simple and intuitive
