About the Role
A fast-growing, pre-seed-funded energy tech startup based in Munich is looking for a Founding Product Engineer to join its early team. The company builds an enterprise-grade, AI-powered SaaS platform that helps industrial companies strategically manage their energy procurement — covering everything from consumption forecasting and flexible procurement to flexibility monetisation.
As one of the first engineers on the team, you will have a decisive say in how the product is built, what the tech stack looks like, and how customers experience the platform. This is a high-ownership, high-impact role for a generalist engineer who thrives at the intersection of product, engineering, and customer collaboration.
No visa sponsorship is available for this position.
What You'll Do
-
Own the full product lifecycle — from design and scoping 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 optimisation problems.
-
Develop performant backend services for a data-intensive application.
-
Build intuitive, elegant user interfaces for a complex decision-support system.
-
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 (currently centred on 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, in direct collaboration with customers.
-
Strong software engineering fundamentals — you build things that are robust, maintainable, and scalable.
-
Hands-on experience building backend services for data-intensive applications.
-
Experience building frontend UIs for complex decision-support or analytical tools.
-
A product mindset: you think about user impact, not just code quality.
-
Comfort with ambiguity and a genuine appetite for fast-paced, early-stage environments.
Strongly preferred:
-
Hands-on experience with time-series forecasting and/or linear optimisation.
-
Familiarity with PostgreSQL, TypeScript, React, and/or Python.
-
Previous experience as a founding engineer, CTO, or technical co-founder at a startup.
Nice to have:
-
Experience with FastAPI and/or Supabase.
-
Interest in or knowledge of energy markets and energy-intensive industrial operations.
-
Corporate engineering background is acceptable if paired with a demonstrated startup mindset and grit.
Compensation & Benefits
-
Salary: €85,000 – €140,000 per year, depending on experience.
-
Meaningful early-stage equity participation (details shared during the process).
-
Direct influence over product direction, tech stack, and team culture from day one.
-
Work alongside an experienced founding team in a well-backed, mission-driven company.
