You will own features end-to-end, from UI and backend services through to LLM prompt design, helping enterprise customers replace fragmented, manual processes with powerful AI agents. The work is high-stakes, highly visible, and shapes the product direction directly. ### What You'll Do * Prototype and ship full-stack product features rapidly across frontend, backend, and LLM integration layers. * Design and refine agent pipelines and prompt workflows that make complex AI behavior feel effortless to end users. * Sit close to enterprise customers, translating feedback and real-world usage into iterated, production-grade experiences. * Reason about system architecture and make pragmatic decisions on when to build, tune, or orchestrate AI components. * Use AI coding tools and agents as a natural part of your development workflow to accelerate delivery. * Contribute across the stack wherever the problem demands, without waiting to be pointed in a direction. ### What We're Looking For * Strong proficiency in full-stack TypeScript; Python experience is a plus. * Demonstrated ability to build with LLMs: prompting, tuning, and integrating them into real, shipped products, whether through professional work, side projects, or hackathons. * Clear evidence of exceptional engineering ability or trajectory, such as impressive shipped products, rapid career progression, notable open-source contributions, or hackathon wins. * Product instincts and creative drive to know what makes an AI-powered experience genuinely good for users. * High agency and entrepreneurial mindset; you find a way rather than waiting for permission. * Experience shipping product in a startup or similarly fast-moving environment. * Comfort working across frontend, backend services, and prompt workflows with full feature ownership. * Reliable, responsive communication and consistent follow-through on commitments. * Based in Berlin and willing to work in person or hybrid with the team. ### Compensation & Benefits * **Salary:** 90,000 to 140,000 EUR annually * **Visa sponsorship:** Not available ### Location Hybrid, based in Berlin, Germany.
