About the Job
About us
Decarbonizing the economy requires a granular, real-time view of where emissions come from and how they might be reduced. We’ve built software to automate the carbon footprinting 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.
As a Junior Python Developer on the Customer Engineering team, you will be the bridge between the data our customers provide and our platform. You’ll be responsible for initial customer data integration, then continue to partner with them to keep their supply chain data flowing into our platform smoothly. You’ll troubleshoot issues, fine-tune our ingestion pipelines, make improvements to data quality so that customers can derive maximum value from our platform.
Responsibilities
Use our existing codebase to map physical production and transportation routes for our customers into digital supply-chain representations
Onboarding of new customers’ data into our platform
Maintain and extend our Python-based ingestion pipelines and data processing utility functions
QA of data uploads to identify and resolve bugs, anomalies or other data quality issues
Ad-hoc data analysis to support requests from our customers and internal teams
Collaborate with our Product and Engineering team to scope and implement system improvements, our carbon accounting specialists to ensure robust emission factor coverage and correct application of methodologies, and our Customer Success Managers to demonstrate value and drive adoption of our product
What we are looking for
1 year working in a technical role, such as a data engineer or python developer, ideally in a commercial setting
Degree in Computer Science or a related field, or equivalent professional experience
Solid Python skills, familiarity with data-pipeline frameworks (e.g., Airflow, dbt or similar) and proficient querying SQL databases (we use PostgreSQL and BigQuery)
Strong ownership; someone who thrives on taking full responsibility for their work.
Curious mindset; thrives on diving into logs, API responses, and error traces to isolate root causes
Familiarity with carbon accounting standards and/or exposure to manufacturing, supply chain or sustainability domains is a plus
Your Growth at CarbonChain
You’ll be supported by experienced engineers who care about your development.
Through regular code reviews, 1:1s and other learning opportunities, you’ll deepen your understanding of data engineering.
As you grow, you’ll take ownership of features, mentor others, and help shape our engineering culture.
CarbonChainer’s receive a ton of great benefits, including:
28 days of annual leave
Home office set up allowance of £500
£2,000 annual learning allowance
Team lunches once a week in the office
£1,000 annual remote work allowance
Office gym and cycle to work scheme
Generous parental leave policy
Private healthcare
You will need to have the right to work in the UK and be willing to work in our central London office at least 3 days a week.
CarbonChain values diversity and inclusion and welcomes applications from candidates with diverse backgrounds.
