You're comfortable shipping into our web app end-to-end - front-end, backend service, API.\n\nStrong Python: You have 5+ years writing production-grade Python. You write clean, well-structured code.\n\nEnd-to-end product delivery: You've shipped AI-powered features into a production web app and owned the integration from research code to real users.\n\nLLM application depth: You have deep hands-on experience building and deploying LLM/agent systems - RAG, tool use, multi-step reasoning, evals.\n\nBackend engineering skills: You design APIs, data pipelines, and services.\n\nProduct mindset: You're comfortable with ambiguity and can judge when something is good enough to ship.\n\nSharp problem solver: You look at a complex system, quickly identify what matters, and decide what to do next.\n\nBias for action: When you're unsure something will work, your instinct is to find out with data rather than keep wondering.\n\nHow We Build: Our Engineering Culture\nWe believe in a calm, collaborative, and productive engineering environment. We trust our engineers and give them the autonomy to do their best work. Our approach includes:\nAgile & Fast-Paced: We practice trunk-based development with daily releases to get value into our users' hands quickly.\n\nQuality by Default: We maintain a comprehensive Cypress E2E test suite and enforce strict typing, linting, and formatting rules to keep our codebase clean and maintainable.\n\nDevOps Mindset: Our well-oiled CI/CD pipeline deploys to AWS via Kubernetes, with our entire infrastructure managed as code using Terraform.\n\nCollaboration & Transparency: We value open discussion, constructive code reviews, and a culture where the best idea wins, regardless of who it comes from.\n\nWhy us?\nCompetitive Compensation: A competitive salary above the market average.\n\nWork-Life Balance: Choose to work 100% remotely or from our modern office in Berlin. We offer flexible working hours to fit your life.\n\nTop-Notch Equipment: A new MacBook Pro to ensure you have the best tools for the job.\n\nA Great Team: Regular company off-sites and team events that connect us as people, not just colleagues.\n\nJob Security: A permanent contract in a stable, well-funded company.\n\nAbout us\nCosuno - Revolutionizing construction through technology.\nWe are Cosuno - a fast-growing tech startup that is making the construction industry more efficient and transparent with our digital platform for tenders and procurement processes.
