Full Stack Software Engineer

About Neutreeno

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.

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.
