Role
Who you are
- Have 8+ years in software engineering with 3+ years in a senior IC role owning developer platform, developer experience, or data platform work
- Have straddled backend and data engineering deliberately. Fluent TypeScript / NestJS, comfortable in Python, experience with a data warehouse (Snowflake, BigQuery, Redshift, or equivalent)
- Have owned DevEx as a first-class product with measurable outcomes: build times, test flakiness, PR turnaround
- Have taken over a system from a single point of failure. You know how to do knowledge transfer well
- Have opinions about test infrastructure at scale and can defend the choices you made in a real codebase
- Have shipped data quality automation: Great Expectations, dbt tests, custom frameworks. You know invariants matter more than assertions
- Are AI-native in your engineering practice (Claude Code, Cursor, or equivalent) and have views on where AI helps and where it does not
- Communicate in writing first and are comfortable with an ambiguous, broad charter you will shape as much as inherit
What the job involves
- We are hiring a Senior Platform Engineer (m/f/d) to become the second senior voice in Platform, alongside our DevOps Lead, and to bridge two worlds he cannot cover alone: application-level developer experience and data engineering
- You will build the automation foundation for the manual data quality checks a single team member has held for years and is now transitioning out of
- You keep our analytics layer running while planning its successor
- You raise developer experience as a measurable discipline
- You are hands-on, you write code daily, and you set the standard for how the engineering group builds and ships
- Own Application & DevEx in the Platform group: developer frameworks, tooling, framework upgrades (NestJS, TypeScript ecosystem), test infrastructure, local dev flow, build pipelines
- Build the automation foundation for Anja's manual data quality checks, pairing with Ghaith and Ghassen who own the check logic
- Bridge DevOps and data engineering. Cover the data layer Hugo does not: Snowflake evolution, product data structures, data tooling landscape
- Keep CubeJS running while architecting the migration off it, in partnership with the Data team
- Raise developer experience as a discipline. Measure build times, test flakiness, PR turnaround. Reduce them
- Cover GDPR posture on the platform side, either directly or in close partnership with whoever the founders bring in for compliance
- Participate in the on-call rotation
- Mentor across squads through code and design reviews. Ship golden paths, templates, and docs that reduce dependence on you
Our take
Climate change and conflicts continue to challenge energy companies, leading to an unprecedented demand for more commitment to renewable raw materials from all stakeholders. For companies, this means it is now no longer a luxury to save CO2 emissions where possible.
Cozero is a software company that creates products to fit that need. The startup was founded to enable companies to effectively decarbonise. It differentiates itself from competitors by framing these CO2 savings in the language of business - each measure details CO2 saved per Euro invested.
With over 70 enterprise customers, the company's next steps will involve accelerating its international expansion and advancing its Climate ERP solution. Having already helped cut Vodafone's media carbon footprint by a third, the company is well set for even greater success as it continues to grow.
