About this role

ABOUT THE ROLE A fast-moving, early-stage startup building an enterprise-grade AI platform for industrial energy procurement and cost optimization is looking for a Founding Product Engineer to join as one of the first engineers on the team. This is a high-ownership, high-impact role where you'll work directly with founders and customers to shape the product from the ground up. The platform is data-intensive and technically deep — spanning time-series forecasting, linear optimization, real-time market data, and complex decision-support UIs for industrial energy buyers.

You'll have meaningful input into the tech stack and product direction from day one. WHAT YOU'LL DO - Own the full product lifecycle from design through deployment. - Translate product objectives into concrete requirements through close collaboration with customers. - Design simple, iterative solutions to complex energy procurement and optimization problems. - Build performant backend services for a data-intensive application.

- Develop intuitive, elegant frontend UIs for complex decision-support workflows. - Train time-series forecasting models for power consumption and renewables production. - Develop linear optimization algorithms that reduce customer energy costs. - Help choose and evolve the core tech stack (PostgreSQL, TypeScript, React, Python). WHAT WE'RE LOOKING FOR Required: - 2+ years of software engineering experience delivering scalable web applications, ideally in an early-stage startup environment.

- Proven ability to deliver full product features independently in close collaboration with customers. - Strong fundamentals for building robust, maintainable, and scalable full-stack web applications. - Experience building backend services for data-intensive applications. - Experience building frontend UIs for complex, data-rich decision-support systems. - A genuine product mindset — you think about outcomes, not just output.

- Comfort with ambiguity and a high-ownership, fast-paced startup culture. Nice to Have: - Hands-on experience with time-series forecasting and/or linear optimization. - Familiarity with PostgreSQL, TypeScript, React, Python, FastAPI, or Supabase. - Background as a startup CTO, founding engineer, or technical co-founder. - Interest in or knowledge of energy markets, industrial operations, or sustainability tech. - Experience at companies in the industrial technology, energy management, or AI/data space.

LOCATION & WORK ARRANGEMENT This role is based in Munich, Bavaria, Germany. You'll be expected to work on-site the majority of the week, with flexibility for occasional remote days. Visa sponsorship is not available — candidates must have an existing right to work in Germany. COMPENSATION & BENEFITS - Salary: €85,000 – €140,000 annually, depending on experience. - Early-stage equity opportunity. - Direct influence over product, architecture, and company direction.

- Work closely with an experienced founding team at the intersection of AI and the energy transition.
