Intro

Every carbon number carbmee produces for a customer starts as someone else's mess: a dozen ERP exports, mismatched supplier spreadsheets, transactional data that doesn't line up with product data, emissions factors that don't map cleanly to anything. As a Sustainability Data Engineer, you build the pipelines that turn that mess into carbmee EIS™'s single source of truth: the foundation of every Corporate, Supply Chain, and Product carbon footprint (CCF, SCF, PCF) we calculate is built on.

This is an infrastructure-and-integration role first, sustainability domain role second, but the two aren't separable here. You'll be the person who decides how a customer's SAP data actually maps into our schema, what happens when a required field is missing, and how a pipeline scales from one pilot customer to twenty enterprise deployments without falling over.

Your tasks

Design and build the ETL pipelines that ingest customer data: PLM/product data and transactional data - from ERP systems (especially SAP), procurement platforms, and flat files, and transform it into carbmee's data model.
Own data quality logic: field validation, deduplication, handling missing values, and encoding the judgment calls (e.g., when missing weight data forces a fallback from activity-based to spend-based emissions estimation) that keep a pipeline from silently producing wrong numbers.
Build and maintain the integrations connecting carbmee EIS™ to customer systems via APIs, custom scripts (Python, SQL), and batch/streaming data pipelines.
Work with LLM-assisted mapping tools (we use Claude extensively) to accelerate transformation work, while building the guardrails that catch when a model would mismap a column it doesn't have context for.
Partner with customer IT and data teams directly to understand system architecture and resolve integration blockers.
Feed recurring data-quality patterns back to carbmee's product and engineering teams so the platform gets smarter with every deployment, not just more scripts.
Contribute to the internal tooling and templates that let the next Sustainability Data Engineer or Forward Deployed Engineer onboard a new customer faster than you did.

Your profile

Who you are

Associate: you have relevant experience (internships, working student roles, or 1-2 years full-time) in data engineering, backend development, or a technical consulting environment, with strong fundamentals in Python and SQL and genuine curiosity about the sustainability domain.

Senior: you have a proven track record building and scaling production data pipelines (ideally including ERP integrations - SAP a strong plus) and are comfortable owning architecture decisions with minimal oversight. Prior exposure to carbon accounting, ESG data, or regulatory reporting (CBAM, CSRD) is a strong plus but not required if your data engineering fundamentals are excellent.

Strong command of Python and SQL; experience with cloud platforms (AWS, GCP, or Azure) and ETL/data pipeline tooling.
Comfort with genuinely messy, real-world enterprise data, and the skepticism to validate rather than assume it's clean.
Ability to work directly with customer technical stakeholders, not just internal teams.
Degree in Computer Science, Data Engineering, or a related field, or equivalent practical experience.
Fluent in English and German.
Based in Munich.
