About this role

ABOUT THE ROLE This is a founding-team engineering role at an early-stage B2B energy-tech startup building an AI-powered platform that helps industrial companies optimise their energy procurement and consumption. You'll have end-to-end ownership of the product — from architecture and backend services to customer-facing UI — and a direct hand in shaping the company's technical direction from the ground up. WHAT YOU'LL DO - Own the full product lifecycle from design through deployment.

- Translate product objectives into concrete requirements in close collaboration with customers. - Design simple, iterative solutions to complex energy procurement and data problems. - Build performant backend services for a data-intensive, real-time application. - Develop intuitive, elegant user interfaces for complex decision-support workflows. - Train time-series forecasting models for power consumption and renewables production.

- Develop linear optimisation algorithms aimed at reducing customer energy costs. - Help choose and evolve the core tech stack (PostgreSQL, TypeScript, React, Python). WHAT WE'RE LOOKING FOR - 2+ years of software engineering experience delivering scalable web applications in an early-stage or high-intensity startup environment. - Proven ability to own and ship full product features independently, working directly with customers.

- Strong fundamentals in building robust, maintainable, and scalable web applications across backend and frontend domains. - Experience with data-intensive backend services; familiarity with PostgreSQL, Python, TypeScript, and React is a strong plus. - Hands-on experience or genuine interest in time-series forecasting and/or linear optimisation. - Experience with FastAPI and/or Supabase is welcome but not required. - Generalist product-minded engineer; a background as a startup CTO or founder is a meaningful plus.

- Comfortable with ambiguity, rapid iteration, and direct customer collaboration. - Curiosity for energy markets and complex, data-driven business applications. - Willingness to work on-site in Munich the majority of the week. COMPENSATION & BENEFITS - Salary: €85,000 – €140,000 per year - Visa sponsorship: Not available LOCATION Hybrid — primarily on-site in Munich, Bavaria, Germany, with flexibility for occasional remote work.
