## Job description

## About CarbonChain

Want to work on the most pressing challenge of our generation? If you have experience building exceptional products, know how to execute at scale, and want to help build a company for the long term, we'd love to hear from you.

CarbonChain helps the world’s biggest supply chains measure and reduce their carbon emissions, using verified primary data where possible, and robust defaults where it isn’t. We build software that turns messy, real-world operational and supplier information into decision-grade carbon and compliance insights, so teams can act: improve sourcing, meet regulations like CBAM, and deliver credible reporting to customers, investors, and regulators.

We’re a product-led company operating in a high-stakes domain. Data quality, auditability, reliability, and trust matter as much as speed. If you enjoy building systems that customers rely on, and shipping improvements that measurably change behaviour across a network, you’ll feel at home here.

Our Product

Our platform combines real-world emissions data with our customers' supply chain information to create actionable insights. We help sustainability teams answer critical questions: Where are the emissions hotspots in our supply chain? Which suppliers should we prioritize? What's the carbon impact of switching vendors or routes?

A major focus of what we’re building right now is supplier engagement and CBAM data management:

- enabling installations (goods producers) to prepare, manage, and share CBAM datasets through guided product carbon accounting workflows;
- improving our supplier database and connection management to support sharing across supply chains;
- and building ingestion pipelines that turn messy customer files into structured, provenance-tracked, insights-ready data.

Beyond CBAM, our platform supports product and corporate carbon footprinting used by some of the world’s largest commodities producers and traders, helping teams move from data collection to credible reporting and decision-making

## About the Role

We're looking for a Staff Software Engineer to help shape the direction of our technology and product. This is a high-impact role for someone who thrives on ownership and autonomy. You'll define problems as much as solve them, working across teams to ship solutions that matter.

As a startup, we move fast and make pragmatic decisions. You'll need to balance speed with quality, navigate ambiguity, and be comfortable with the fact that your role will evolve as our customer base grows.

## What You'll Do

- Partner with our Head of Engineering to design architecture and implement the most challenging parts of our system
- Take full ownership of projects from conception to delivery - you'll drive initiatives forward without waiting to be told what to do
- Collaborate with Product Managers to define new projects, plan work, and advise on technical feasibility
- Work across teams - whether that's Sales, Customer Success, or Carbon Team - to understand needs and deliver solutions that work in the real world
- Mentor engineers and help level up the team through code review, technical discussions, and setting engineering standards
- Be comfortable with ambiguity and changing priorities - startup life means adapting quickly while keeping the big picture in mind

## What We're Looking For

- 8+ years delivering complex software systems and getting large scale user adoption
- Deep expertise in modern web applications and distributed systems
- Strong collaboration skills - you work closely with Product to ideate features, advise on trade-offs, and iterate on what we've built
- Experience with Python and TypeScript (we value versatility and broad knowledge over memorizing PEPs)
- Proven ability to design and implement cloud-based system architectures
- Knowledge of IaC/Terraform and modern CI/CD practices
- Bonus: experience with data-intensive systems
- Bonus: experience building SaaS and enterprise applications

## What We Offer

Meaningful impact and accelerated growth

This is a rare opportunity to work on technology that directly addresses the climate crisis while shaping the future of a fast-growing company. You'll have significant influence over our technical direction and product strategy - the kind of impact that typically takes decades to achieve elsewhere.

You'll tackle diverse challenges, work across the full stack of problems (technical and otherwise), and own meaningful projects from start to finish. If you want to learn quickly, take on real responsibility, and see the direct results of your work, this is the place to do it.

Competitive salary and benefits:

- 28 days annual leave
- £500 home office setup allowance
- £2,000 annual learning allowance
- Private healthcare
- Generous parental leave policy
- Weekly team lunches in the office
- Office gym, and cycle to work scheme

CarbonChain values diversity and inclusion and welcomes applications from candidates with diverse backgrounds.

If you think your skills and experience match what we’re looking for and you’d like to join the next Climate Tech industry unicorn, please get in touch!
