Founding Product Engineer

About the Role This is a founding engineering hire at an early-stage, AI-powered platform built for industrial energy procurement and cost optimisation. You'll join a small, high-conviction team and take genuine ownership — from shaping the architecture to shipping features directly with customers. The platform handles real-time energy market data, forecasting, portfolio management, and optimisation at enterprise scale. If you're a generalist engineer with a strong product mindset, comfort with ambiguity, and a curiosity for data-intensive domains, this role is a rare opportunity to have outsized impact from day one. Note: Visa sponsorship is not available for this role. What You'll Do Own the full product lifecycle — from design and requirements through to deployment and iteration. Translate product objectives into clear, actionable requirements in close collaboration with customers. Design simple, iterative solutions to complex energy procurement and market problems. Build performant backend services for a highly data-intensive application. Develop intuitive, elegant user interfaces for a sophisticated decision-support system. Train time-series forecasting models for power consumption and renewables production. Develop and refine linear optimisation algorithms to reduce customer energy costs. Help define and evolve the core tech stack — including PostgreSQL, TypeScript, React, and Python . What We're Looking For Must-haves: 2+ years of software engineering experience delivering scalable web applications in an early-stage startup environment. Proven track record of delivering full product features independently, working directly with customers. Strong software engineering fundamentals — you write robust, maintainable, scalable code. Hands-on experience building backend services for data-intensive applications. Experience building frontend UIs for complex, data-rich decision-support tools. A genuine product mindset: you think about outcomes, not just outputs. Comfort thriving in a fast-paced, early-stage environment with high ambiguity and rapid change. Strong advantages: Experience with time-series forecasting and/or linear optimisation. Familiarity with PostgreSQL, React, Python ; exposure to FastAPI, TypeScript, or Supabase is a plus. Background as a CTO, founding engineer, or startup founder. Corporate background (e.g. industrials, energy, consulting) paired with a demonstrated startup mindset and grit. Curiosity for energy markets, industrial technology, or data-intensive B2B applications. Location This role is based in Munich, Germany . You'll work on-site the majority of the week, with flexibility for occasional remote days. Fully remote arrangements are not available for this position. Compensation & Benefits Salary: €85,000 – €140,000 per year, depending on experience. Meaningful early-stage equity participation. Direct influence over product direction, tech stack, and company culture. A lean, high-calibre team working on a complex, high-stakes problem in the European energy transition.
