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.
