About Carbon Chain

Want to work on the most pressing challenge of our generation If you want to build exceptional products execute at scale and want to help build a company for the long termwedlove to hear from you.

Carbon Chain helps the worlds biggest supply chains measure and reduce their carbon emissions using verified primary data where possible and robust defaults where itisnt. We build software that turns messy real-world operational and supplier information into decision-grade carbon and compliance insights so teams canact:improve sourcing meet regulations like CBAM and deliver credible reporting to customers investors and regulators.

Werea product-led companyoperatingin 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 changebehaviouracross a networkyoullfeel 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

Whatsthe carbon impact of switching vendors or routes

A major focus of whatwerebuilding 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 carbonfootprintingused by some of the worlds largest commodities producers and traders helping teams move from data collection to credible reporting and decision-making.

Decarbonizing the economy requires a granular real-time view of where emissions come from and how they might be reduced. Weve built software to automate the carbon foot printing of supply chains. Banks traders and manufacturers use our product to tame the complexity of international supply networks identify the most carbon-intensive parts and find lower-carbon alternatives.

About the Role

We're looking for a Junior Data Engineer to join the team thatmaintainsour trades & emissions dataset and the ingestion pipeline that feeds it. This is the data at the heart of our product: every customer brings their own trade and supply chain data in their own formats and with their own quirks and turning it into reliable carbon-accounted insight is what this team does.

This is an early-career role with a strong emphasis on on well-defined tasks with supervision ingesting customers data writing SQL to investigate andvalidateit and making fixes and improvements to the pipeline while building fluency with our data our tooling and modern engineering deep domainexpertisein supply chain and commodity trade data that very few engineers in the industry have.

What Youll Do

• Ingest customers trade and supply chain data under guidance:analyse map and transform it into our data models

• Write SQL against our dataset to answer questions investigate data issues andvalidatethat customer data behaves as expected

• Apply validation and sanity checks and learn to spot the usual suspects: nulls duplicates late-arriving data

• Build simple ingestion and transformation steps and make well-scoped fixes and config changes to the pipeline

• Contribute to dashboards and internal tooling following existing patterns

• Learn our monitoring: what a healthy pipeline looks like how to triage alerts using runbooks and how to escalate with useful context

• Build domain knowledge of how trade and supply chain data maps to carbon accounting asking questions and documenting assumptions as you go

What Were Looking For

• Some hands-on experience with Python and SQL professional academic or personal projects all count

• A rigorous detail-oriented approach to working with messy real-world data

• Comfort asking questions seeking feedback and learning fast

• Ownership mindset: you see your tasks through rather than handing them off

• Strong communication skills youllwork with customer data and alongside customer-facing teams

• Passionate about climate and sustainability

• Bonus: exposure to data tooling such asBigQuerydbt or BI tools like Metabase

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 influence over our technical direction and product strategy - the kind of impact that typically takes decades to achieve elsewhere.

• Youlltackle 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 thisis the place to…
