Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Backend Engineer (Infrastructure & Platform) - **Company:** Zeit Gmbh - **Location:** München, Germany - **Salary:** €95,000.0 - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Cloud Computing, Virtual Private Networks (VPN), PostgreSQL, Online Analytical Processing, Online Transaction Processing, TypeScript, Data Processing, ReactJS, Large Language Models, Backend, Data Management, Front End Software Development, Docker - **Published:** July 11, 2026 - **Apply:** https://de.indeed.com/viewjob?jk=d4bf53080fe59848 ## About the Role * You've been a lead architect or equivalent: built many systems yourself, and seen how large systems fail and evolve. You're here to learn from customers and take bets on a product that doesn't exist yet, not to learn how to write software. * Strong TypeScript and cloud infrastructure experience * English C1 or above; German a plus ## Description * Build the sync layer: millions of rows from ERP, CRM, and homegrown systems, ingested incrementally and reliably, without an engineer babysitting the pipeline * Cut onboarding time: connecting a new customer's data sources should take hours, not weeks. You abstract sources so our agents work with any of them the same way * Make the agent fast where it counts: speed comes from tool design that parallelizes, sub-agents, and branching, not tokens per second. You design tools so work can run concurrently and safely * Route data safely between customer networks and ours: security and reliability are features our customers pay for * Build the guardrails for correctness: automatic checks and integrated validation tooling so the agent's output can be trusted, and so it flags what a human should verify * Keep the platform simple: choose boring technology where boring wins, and be able to say why every system we run earns its place You will thrive here if you * have built or scaled data platforms before and think clearly about data processing architectures * have a deep understanding of OLAP and OLTP systems and when to reach for each * bring strong backend experience with TypeScript and are at home in cloud infrastructure * get foundations right without overengineering them; you build for the scale we will hit next year, not for a hypothetical one * take full ownership from idea to production to impact, and are comfortable working without predefined specs * want to build foundations early rather than optimize mature systems * are genuinely interested in the data and agentic space and how LLMs enable new workflows for non-technical users, * Regular San Francisco offsites for product sprints and staying close to the frontier. * Zeit AI package: daily lunch allowance, free in-office dinner, wellpass membership, best tech & tools * You know someone? €5k referral bonus for every successful hire. Tech stack TypeScript end to end. Backend on Bun with Postgres and Supabase. React frontend (Mantine, TRPC, TanStack Query). Job/Process management, Docker, VPN/routing and Agentic frameworks: harness, tool calls, sandboxed tools, branching of data and specs. About the interview process * First call with Elisa * Tech screening * Tech interview with Jonas * Decomposition interview * Second technical interview * Behavioural interview * Take-home case + Meet the team * References, offer ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Empowering Thousands of Developers: Our Journey to an Internal Developer Platform](https://www.wearedevelopers.com/videos/1519-empowering-thousands-of-developers-our-journey-to-an-internal-developer-platform) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [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) ## Related Articles - [Backend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/196-backend-developer-salary-in-germany-2023) - [Frontend Developer Salary in Germany [2023]](https://www.wearedevelopers.com/magazine/195-frontend-developer-salary-in-germany-2023) - [The Biggest German Tech Companies](https://www.wearedevelopers.com/magazine/424-the-biggest-german-tech-companies) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Finding Jobs in Germany](https://www.wearedevelopers.com/magazine/375-finding-jobs-in-germany) - [Where to Find German Tech Jobs](https://www.wearedevelopers.com/magazine/366-where-to-find-german-tech-jobs)
