You'll be responsible for the technical backbone of our product—shaping architecture decisions, evolving production systems, and setting the engineering standard as our team grows:
-
Define and evolve our backend architecture—making strategic decisions on service boundaries, data flows, and scaling patterns.
-
Design and build high-throughput content ingestion and transformation pipelines that reliably process thousands of articles daily.
-
Own the full lifecycle of our core API services (FastAPI)—from design through deployment to operational excellence.
-
Establish backend engineering standards: code quality, testing strategies, documentation practices, and review processes.
-
Drive infrastructure decisions—evaluate trade-offs between cloud services, optimize costs, and ensure our systems are observable and resilient.
-
Mentor and guide future engineering hires as the team scales.
-
5+ years of professional Python development, with significant experience designing and operating production backend systems
-
Deep knowledge of async frameworks (FastAPI or equivalent) and RESTful API design
-
Strong data modeling skills—MongoDB or other document/NoSQL databases at scale
-
Solid understanding of distributed systems patterns: queues, event-driven architectures, idempotency, graceful degradation
-
Hands-on experience integrating and orchestrating LLM APIs (OpenAI, Anthropic, or similar) in production
-
Familiarity with LangSmith, LangChain, or comparable orchestration/observability tooling
-
Ability to reason about prompt engineering trade-offs, token economics, and model selection
-
Up to date and clear on pros and cons of agent-assisted software developement
-
Production AWS experience (ECS, Lambda, S3, SQS, or similar services)
-
Docker, CI/CD pipelines (GitHub Actions), infrastructure-as-code
-
Hands-on with monitoring, logging, and alerting—you've been on-call and know what matters when things break
-
You think in systems, not just features—anticipating failure modes and scaling bottlenecks before they hit
-
You make pragmatic trade-offs between moving fast and building for durability
-
You communicate technical decisions clearly, both in writing and in conversation
-
You've operated in environments where you had to define process, not just follow it
-
You love to deploy as often as you can and to test in production
Experience in early-stage or high-growth startups is a strong plus. You excel at taking ownership, handling ambiguity, and understand that sometimes you have to throw away your own code.
-
You've established architectural patterns and engineering practices that the team builds on confidently.
-
The systems you own run reliably in production with clear observability—issues are caught before users notice.
-
Your technical judgment earns trust across the team, and your decisions hold up as we scale.
-
Editors and internal users experience a noticeably more stable, faster product.
-
Shape the technical foundation of a product used by major German publishers.
-
Be the senior engineering voice in a small, high-impact team with direct influence on product and architecture.
-
Support trustworthy journalism in the age of AI.
-
Berlin-based hybrid setup with genuine home office flexibility.
-
Early-stage equity opportunity—your work directly drives company value.
