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.
