We’re bringing the energy transition to apartment buildings — roof by roof!

Solar energy is booming - but so far, it’s mostly single-family homes that benefit from affordable, green electricity. Apartment buildings? Not so much. Only about 1% currently have solar panels in Germany. We want to change that - and we need you to help bring affordable solar power to thousands of people!

Your mission

You’re a builder. As a founding engineer, you will build our tech team and software platform for tenant electricity from the ground up. You have deep technical expertise, work lean, ship fast, and take on versatile tasks with full ownership.

You know exactly when it’s time to create a scalable product and when “vibe coding” is perfectly fine. You’re not just shaping the codebase but also defining the technical vision of our product. That way you are actively contributing to the energy transition. ☀️

Who we are

Dach für Dach is revolutionizing Mieterstrom for small apartment buildings - simple, digital, and hassle-free. We support property owners and installers throughout the entire journey, from planning and implementation to operations. Our innovative software ensures transparency across all stages, visualizes energy data, and automates billing.

We’re Jasper and Leo, the founders of Dach für Dach. With our backgrounds in software startups, venture capital, and industry, we share a mission: to provide even more people with sustainable and affordable energy.

Build products from scratch
Take full technical ownership of our software platform
Develop and ship new features together with us, e.g., energy data visualization or automated billing

Requirements

Hands-on mindset: You proactively tackle challenges and push our product forward with ownership
You solve problems quickly and pragmatically without overengineering
You know when to use no-/low-code solutions and AI tools - and when “vibe coding” becomes an issue
Full-stack expertise: Strong skills in both frontend and backend technologies
Self-leadership & curiosity: You organize yourself independently and dive fearlessly into new topics
Languages: English, basic German
Passion for the energy transition and a drive to turn ideas into reality
Bonus: Experience with energy or billing software

Benefits

Direct collaboration with the founders & fast track to ownership
Fair salary: depending on experience level + equity (VSOP)
The opportunity to actively shape the energy transition and build a new company from the ground up
This is not a remote position: We’re in our office in the heart of Berlin 3–5 days a week and look forward to building a great team with you here.

⚠️ Important: We know no one ticks every box. If our mission resonates with you and you’re excited to make an impact - definitely apply!

We don’t care about a “perfect” résumé but about your drive to get things done. Have a project you’re particularly proud of? Tell us about it in your application! :)
