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 Product Engineer who thrives at the intersection of engineering, product, and customers. This is a full-stack role with a frontend and product focus - you'll build features that users love and stick around to see how they're adopted.
You'll work closely with Product Managers, commercial team, and customers to ship solutions that solve real problems. We're looking for someone who's worked in a startup environment and knows how to move fast, iterate based on feedback, and build with the customer in mind.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You'll Do
- Build end-to-end features across the full stack, with a focus on creating polished, intuitive user experiences
- Own features from ideation through to user adoption - you'll help define what we build, ship it, and measure its impact well after go-live and show true customer obsession
- Work directly with customers to understand their needs, gather feedback, and validate solutions
- Collaborate closely with Product Managers and designers to turn ideas into shipped features, making trade-offs and iterating rapidly
- Partner with teams outside of Product & Engineering - like Sales, Customer Success, and Carbon Team - to understand how our product is used and what problems need solving
- Build with modern frontend technologies while being comfortable diving into backend work when needed
- Contribute to product thinking and help shape our roadmap based on what you're seeing and hearing from users
- Think critically and pragmatically - ship MVPs quickly to learn from REAL users, and iterate
What We're Looking For
- 3+ years building applications across the full development lifecycle
- Experience developing modern web applications, ideally in a startup environment
- Strong collaboration skills - you work closely with Product to ideate features, advise on trade-offs, and iterate on what we've built
- Passion for building customer-centric products and genuine curiosity about user problems
- Experience working on features from ideation through to driving user adoption
- Expertise in TypeScript and modern frontend development (experience with Angular is a plus)
- Full-stack capabilities - comfortable working with Python backends (Python expertise is not a strict requirement)
- Knowledge of relational databases, job queues, cloud infrastructure and how web applications work end-to-end
- Comfortable with the startup pace and pragmatic decision-making
- Bonus: SaaS or B2B product experience
- Bonus: experience in climate tech or sustainability
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.
Get help with your application
Your very own career expert that helps elevate your application to the next level.
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.
