About the role

Senior Software Engineer developing technical backend infrastructures for renewable energy solutions at Solarize. Focused on innovative system designs and performance for energy management applications.

Responsibilities

As a Senior Software Engineer (m/f/d), you won’t just develop software—you’ll build the technical backbone for a sustainable future, creating scalable architectures that deliver real solutions.
Take full ownership—from architecture to release: product-driven development here means building solutions that make a real difference for the energy transition, not just closing tickets.
You will develop innovative, AI-powered features that elevate energy management and create measurable impact.
You will design, develop, and maintain high-performance microservices that form the technical foundation of our product vision.
You are responsible for integrating, processing, and storing large volumes of measurement data as well as scaling our billing logic.
You evaluate and actively introduce modern backend technologies, tools, and deployment pipelines to continuously improve our platform.
You work within an experienced engineering team across the entire product lifecycle and ensure our software integrates seamlessly with existing systems.
You act as the technical interface to product management and stakeholders, translating requirements into clean code and ensuring clarity and focus during development.

You have at least 5 years of professional software development experience and are eager to take technological responsibility for the success of our solutions.
You are confident in the Node.js and TypeScript ecosystem and have solid knowledge of relational database systems, particularly PostgreSQL.
You love turning complex requirements into clean code. You are experienced in building and testing APIs and translating abstract business needs into performant technical features.
You have experience deploying to and using cloud infrastructures (e.g., Google Cloud) and know your tools (e.g., Git, NPM, Docker) inside out.
You don’t get lost in the details; you keep scalability and the architectural "big picture" in mind.
Agile development methodologies are not a buzzword to you, but practiced daily.
Excellent German and English skills.
