Senior Backend Engineer | TypeScript | GreenTech Startup | Berlin / Hybrid | 90.000 EUR | 🌱 Code for a cleaner future

We’re a Berlin-based green energy startup on a mission to accelerate Europe’s transition to renewable power. Our platform helps households, cities, and companies understand, manage, and reduce their carbon footprint — and we need your TypeScript skills to make it happen.

Why Join Us?

• You’ll write software that genuinely matters: every feature you ship helps cut emissions and shape a more sustainable future.
• You’ll be part of a small, ambitious, multicultural team in Berlin that loves solving hard problems — minus the corporate nonsense.
• You’ll have real ownership: from architecture decisions to shipping features, your voice matters here.

What You’ll Do

• Build elegant, reliable TypeScript solutions across our stack (React/Next.js frontend + Node.js/NestJS backend).
• Translate complex energy data into simple, beautiful user experiences.
• Collaborate with product, design, and data teams to create tools that empower people and businesses to go green.
• Contribute ideas to our roadmap — whether that’s optimising solar energy forecasts, building new dashboards, or scaling APIs.
• Keep an eye on performance, testing, and code quality while helping us grow sustainably.

What We’re Looking For

• Strong professional experience with TypeScript (frontend, backend, or ideally both).
• Familiarity with modern frameworks (React, Next.js, Node.js, NestJS).
• A pragmatic engineer who values clean code, maintainability, and impact over perfection.
• Comfortable working in German (spoken and written) for team and partner communication.
• Based in Berlin (or planning to relocate) and happy with hybrid working (2x/week in our Berlin office).

What We Offer

💶 Salary: ~€90,000/year (flexible based on experience)

🏡 Hybrid work: 2 days office, 3 days remote

🌍 Extra paid "Green Days" off — volunteer with an NGO or work on your own sustainability project

🚲 Monthly allowance for a bike, public transport, or e-scooter

☀️ Subsidised solar panels / green energy package for your home

🍃 Carbon offset for your work travel, plus we plant trees for every new teammate

📚 Personal learning budget & conference trips

🎉 Regular eco-friendly team events (think hiking, urban gardening, kayaking, not just beers)

🚀 A chance to shape both our product and our engineering culture from the ground up
