Jobs in Duisburg, Germany

RemoteSolar enables anyone (including renters) to benefit from solar energy without installing anything at home. Our customers get access to clean power from large-scale solar parks and gain more stability and independence from volatile energy prices. We take care of all the complexity so the experience stays simple, transparent, and intuitive.

We’re a small, committed team with big plans, building a product that lets people participate directly in the upside of solar in just a few steps.

We’re looking for a Senior Software Developer who likes to work close to real customer problems and build practical, well‑crafted solutions. You’ll work directly with the founder and early team, shaping how our product works, how our system grows, and how customers experience RemoteSolar from day one.

There’s significant ownership, and as we grow, the path toward a tech‑lead or engineering leadership role is open if you want it.

• Build and improve core features of our Ruby on Rails platform
• Work end‑to‑end: understand the problem, design, implement, iterate
• Turn customer needs and business priorities into clear technical decisions
• Collaborate closely with team members across product, operations, and marketing
• Ensure stability, performance, and reliability of our system
• Contribute to architecture, tooling, and development practices
• Keep a practical mindset: ship, learn, adjust
• Focus on delivering real value to customers

• 5+ years of professional software development
• Strong experience with Ruby on Rails
• Comfortable in a fast‑moving, early‑stage environment
• Practical, solution‑oriented mindset
• Ability to understand the “why,” not just the “what”
• Clear communication and cross‑team collaboration
• Located within ±2 hours of CET
• English proficiency; basic German understanding
• Interest in growing with the company (leadership optional)

• High impact
  • You directly shape the product, customer experience, and engineering approach.
• Fast learning and real ownership
  • Work closely with the founder, take responsibility, and influence decisions beyond engineering.
• Meaningful mission
  • Your work helps people gain more independence from rising energy costs and take part in Europe’s transition to clean energy.
• Flexibility and trust
  • Remote‑first, outcome‑focused culture with freedom in how you work.

• Up to €90,000 salary (experience/location dependent)
• 28 vacation days
• Your birthday off
• Indefinite contract after 3‑month probation
• Remote‑first culture with optional meetups

If you enjoy creating products that deliver real value, care about customer experience, and want meaningful impact, we’d love to talk.
