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.

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).

Benefits

What We Offer

Compensations & Benefits:

£45,000 - £65,000 base pay dependent on your skills, qualifications and experience.
25 days annual leave.
Year-end performance bonus.
Meaningful equity stake. We want you to think and benefit like an owner as the company grows.
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 for personal travel, in addition to regular holiday policy (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, and more).

Culture & Growth:

A 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 here and a cover letter 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.
