Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Platform Engineering - Remote (DE, UK, PT, ES) - **Company:** Cozero - **Location:** Berlin, Germany (Remote available) - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, BigQuery, Information Engineering, Data Infrastructure, Data Warehousing, Cursor (Graphical User Interface Elements), DevOps, Python (Programming Language), Software Engineering, TypeScript, Delivery Pipeline, Snowflake, Backend, Data Layers, NestJS, Amazon Redshift - **Published:** August 7, 2026 - **Apply:** https://de.indeed.com/viewjob?jk=1e1c8e1a27ed7f9e ## About the Role * 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. ## Description 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., * Real technical challenge - You're joining a growing system with real complexity. Work directly reduces carbon emissions at scale. Not theoretical, actual tons of CO2. * Actual climate impact - Series A funded, growing fast, working with enterprise customers who trust us with their decarbonization journey. * Exceptional team - Work directly with our founders. And 10+ engineers across Germany, Portugal and the UK. Multicultural, senior-leaning, collaborative, and actually passionate about climate action. * You'll grow fast - Flat hierarchy. Your ideas ship. Direct impact on product and strategy. ## Related Videos - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Next, Nest, Nuxt… Nust?](https://www.wearedevelopers.com/videos/421-next-nest-nuxt-nust) - [Streaming AI Responses in Real-Time with SSE in Next.js & NestJS](https://www.wearedevelopers.com/videos/1630-streaming-ai-responses-in-real-time-with-sse-in-next-js-nestjs) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs)
