Java software engineer Jobs in Köln

We’re seeking an accomplished Staff Software Engineer (Django specialist) to serve as the go-to expert for one of Europe’s fastest-growing legal-tech scale-ups. Our AI-enabled products are already in the hands of thousands of law-firm and in-house customers; now we need the deepest Django expertise to harden and extend the platform’s core while we accelerate feature velocity and market expansion.

Reporting directly to the Head of Engineering , you will own our most complex services and architectural decisions, shaping everything from database schemas and asynchronous task flows to performance tuning and security hardening. Familiarity with Vue 3 or modern frontend tooling is required to enable you to work on features from end to end.

For a builder who thrives on untangling intricate code paths, crafting elegant abstractions, and elevating team capability through example and guidance, this role offers uncommon influence on a modern, cloud-native platform poised for rapid growth.

Your Challenge and Opportunity in This Role

This is a rare chance to define—at staff-engineer depth—how a rapidly expanding product is designed, shipped, and maintained. As our resident Django authority, you will translate nuanced product requirements into resilient, scalable software; establish service boundaries, migration strategies, and CI / CD guardrails; and ensure our Python stack is battle-tested in production. Expect genuine ownership of mission-critical code, a seat at the table for technical strategy, and the ability to shape how our engineering organisation solves its hardest problems as we scale across markets and use cases.

Tasks

• Design and evolve sophisticated systems that meet performance, security, and maintainability goals.
