🐍 Senior Backend Engineer

About Interloom

Interloom is building the first navigation system for work.

For thirty years, enterprise software has forced fluid, human work into rigid forms, tickets, and CRMs. Yet most of what actually happens inside a company, the decisions, the escalations, the problem-solving, happens outside those systems. Roughly 70% of operational knowledge is never written down. It lives in inbox threads, support tickets, and the heads of experienced people. Interloom changes that. We capture how expert teams actually resolve work and turn it into a living context graph, a permanent memory layer that lets AI agents act on your company's real, proven decisions instead of generic training data.

We put subject-matter experts, not developers, in control. Everything in Interloom is built from natural language: a procedure is written the way you would explain it to a new colleague, and an agent is briefed the way you would brief a contractor. We are already deployed at enterprises like Zurich Insurance, JLL, and Fiege, across facility management, insurance, banking, logistics, energy, and ITSM.

We are a team of engineers, operators, and researchers across Munich and Berlin. In March 2026 we raised a $16.5M seed round led by DN Capital, with participation from Bek Ventures and Air Street Capital, to expand across enterprise customers and accelerate our go-to-market. If you want to do the best work of your life on a hard, real problem, we want to hear from you.

How we work

• Experts in control. The people closest to the work design it. We build for the operator, not the developer, and we work the same way internally.
• Describe, then automate. If it can be described clearly, it can be built. We value precise thinking and plain language over jargon and ceremony.
• Context compounds. We do not let knowledge disappear. We write things down, learn from every case, and make the next decision better than the last.
• Humans make the call. Agents handle the routine so people can focus on the highest-value work and the decisions that matter.
• Small teams, real ownership. Lean, autonomous teams with minimal bureaucracy. You own outcomes, not tasks.
• Ship to learn. We put working software in front of real users early and let evidence, not opinion, decide what comes next.

About the role

We are looking for an experienced Python engineer to help build the scalable backend behind Interloom’s context graph, the memory layer that lets AI agents act on a company’s real, proven decisions. You will shape and optimize our APIs, architecture, and workflows as we expand across enterprise customers, working with a small, senior team that ships fast and owns outcomes end to end.

What you’ll do

• Own and drive the backend tech stack.
• Design and build scalable systems that power the context graph and agent runtime.
• Set up and maintain testing best practices.
• Ensure system reliability and performance as we grow.
• Collaborate across engineering, product, and go-to-market teams.
• Stay current with backend innovations and bring the best ideas in.

What we’re looking for

• 5+ years of professional experience in backend development with Python.
• Deep understanding of Python internals, including memory management, garbage collection, and the Global Interpreter Lock (GIL).
• Proven experience with Python frameworks like FastAPI, Django, or Flask.
• Proven experience setting up and maintaining testing frameworks (unit, integration, and performance) and ensuring code quality with tools like ruff and mypy.
• Technically fluent. Comfortable with APIs, building automations, and thinking in systems.
• Familiar with CI/CD practices, performance monitoring, and profiling.
• Effective communicator and collaborator across cross-functional teams.
• Fluent in English.
• Nice to have: knowledge of Docker, Kubernetes, and Terraform.

Compensation and benefits

• 💰 Salary: €70,000 to €95,000. Final offer depends on experience.
• 📈 VSOP: Virtual stock options, so you share in the upside you help build.
• 💻 Pick your own workstation and hardware. We give you the tools you need so nothing slows you down.
• 🏢 Cozy, comfortable offices in Munich and Berlin.
• 🔄 Hybrid work mode, so you can work in the way that gets your best performance.
• 🌍 Annual company retreats to spend real time with the team.
• 🤖 Groundbreaking work in AI and ML, pushing the boundaries of what agents can do.
• 👥 A collaborative, high-trust environment built for high performance.
• 🚀 Professional growth with clear pathways to leadership as we scale.

Location

This role is based in Berlin, with a hybrid setup out of our office (Leuschnerdamm 13, Berlin). Working hours aligned to Central European Time, with occasional travel between offices and to team offsites.
