Senior Backend Engineer

About the Role

This is a senior backend engineering role at an early-stage, Y Combinator–backed AI supply chain startup focused on the Consumer Packaged Goods (CPG) sector. You'll join a small, fast-moving engineering team in Munich to own the backend systems that power an AI-driven supply chain manager — turning the messy, real-world flow of physical goods into programmable, reliable, and scalable software.

What You'll Do

• Design and implement backend systems that drive AI-powered supply chain planning and execution decisions.

• Architect data models and pipelines to ingest and organize complex, unstructured real-world data.

• Ensure user requests and supply chain plans are processed in real time with high reliability.

• Build scalable, high-performance SQL queries and data access patterns across large datasets.

• Ship production-grade services using modern backend frameworks and testing best practices.

• Collaborate closely with the core product and engineering team to translate logistics operations into software.

• Operate and improve deployment and runbook processes to maintain 24/7 system uptime.

What We're Looking For

• 5+ years of experience as a Backend Engineer with a strong track record of shipping real products.

• Hands-on proficiency with Python and modern backend frameworks such as FastAPI, and testing tools like pytest.

• Strong SQL skills, including writing high-performance queries over millions of data points.

• Experience designing scalable data architectures and owning backend systems end-to-end, including real-time request processing.

• Comfort managing and organizing messy, unstructured real-world data at scale.

• Experience with AI-assisted code generation and management tools (e.g., Claude Code, Codex), including parallelizing instances for continuous operation.

• Solid system design instincts with the ability to work autonomously and make sound engineering trade-offs.

• Familiarity with unstructured data ingestion systems, DevOps practices, and AWS.

• Exposure to frontend frameworks and their testing is a plus.
