Who we are

At GALVANY, we drive the energy transition through software. We’re building an AI-based Operating System for sales, planning, installation and operation of heat pumps and integrated energy systems – from single-family homes to multi-unit buildings, and across our Energy Community as a Virtual Power Plant. GALVANY is a profitable, fast-growing company backed by leading investors.

The role

As a Backend Engineer at GALVANY, you'll design, build, and optimize scalable backend systems that power our AI-based Operating System for heat pumps and energy management, ensuring seamless performance from sales to operations in single-family homes, multi-unit buildings, and our Virtual Power Plant.

  • Develop robust APIs, data integrations, and services to handle complex energy workflows, with a focus on stability, observability, and scalability to directly support end-users.
  • Collaborate with cross-functional teams to implement features that drive the energy transition.
  • Leverage AI and LLMs to enhance backend solutions and stay ahead in the Gen AI landscape.

Tech Stack: Backend with GoLang; ML with Python, PyTorch, and LLMs; Frontend with React, Tailwind, and Shadcn; Mobile with Flutter; General tools including Azure, GitHub, Linear, Notion, Kafka, Benthos (data pipeline), Kestra (workflow engine), and low-code process automation platforms.

What we value

  • Ownership. Take end-to-end responsibility. Fix systemic issues, not just symptoms; champion long-term health over short-term wins.
  • Product Thinking. Outcome over output. Build with user empathy, business context, and data – not just code. Validate assumptions early and measure whether features create real value.
  • Curiosity. Ask “why?” relentlessly. Seek new perspectives, challenge assumptions, and share learnings openly – both inside and outside the team.
  • Pragmatism. Choose the simplest effective path. Make smart trade-offs, consider low-code and AI tools, and prioritize reuse of libraries, services, and patterns over reinventing the wheel.
  • Team First. Team over ego: win and learn together. Elevate collective goals, communicate transparently and share successes and failures openly.

What We Require

  • Experience. 4+ years of experience in high-performance environments (e.g., top-tier consulting, fast-scaling startups, or similar).
  • Track Record. Proven end-to-end responsibility in software engineering. From ideation to release.
  • Background. Strong background in relevant fields, e.g., Computer Science, Software Engineering, or similar.
  • Technical Skills. Strong coding skills with proficiency in relevant languages such as Go, Python, or similar.
  • Mindset. Self-driven problem-solving mindset – no need for micromanagement or specific tickets.
  • Technical Aptitude. Technical mindset with a passion for understanding systems, data flows, and integrations, coupled with enthusiasm for continuous learning and problem solving.
  • Language. Fluent in English; German is a plus.

What we offer

  • Real-World Impact. Your work drives decarbonization – measurable in CO₂ savings, energy efficiency (kWh), and cost reductions (€).
  • Perks. Prime office location in Berlin Charlottenburg, high-quality subsidized lunch, regular company events and all-hands.
  • Compensation. Attractive package with VSOP opportunity.
  • Strong Growth & High Impact. A unique opportunity to join during a hypergrowth phase and actively contribute to company success.
  • Open Culture. Flat hierarchies, short decision-making paths, and a collaborative, dynamic environment.
