(Senior) Full Stack Developer (m/f/d) Heat Fleet

At Vamo, our mission is to bring about a new era of heating into homes. To achieve this, we connect modern, efficient, and environmentally friendly heat pumps across Germany with our Heat Fleet (our Fleet management platform for employee) and the Vamo App (our mobile App for end customers). Heat Fleet and the App are built by an interdisciplinary team of developers, and designers working as one scrum team. As our Senior Developer, you will be the technical heart of this team. ​

Tasks:

• Development & Implementation: You will participate in the conception, development, and implementation of new, complex features for our Heat Fleet. This encompasses everything from architectural design in the backend (Node.js) to driving the execution in the frontend (Vue.js), setting and ensuring adherence to technical guidelines and balancing the introduction of new features with careful management of any potential technical debt.
• API Design & Architecture: Together with our staff full stack engineer, you will be instrumental in the design, standardization, and implementation of robust, highly scalable, and future-proof APIs. These APIs serve as the central communication interface for thousands of heat pumps and our mobile application, demanding the highest standards for performance and reliability.
• Code Quality & Testing: You will establish and uphold high standards for code quality, maintainability, and test coverage (unit and integration tests) within the team. This involves defining and following code conventions, conducting code reviews, and mentoring other developers to continuously improve development quality.
• Team Collaboration & Stakeholder Engagement: You will be an integral part of an interdisciplinary development team, working closely with designers, and other stakeholders throughout the company. Everyone in the team is involved in (and responsible for) the technical analysis of ideas, new features and requirements and translating them into outstanding, actionable technical solutions. You will also get the chance to discuss and influence our roadmap and defend your ideas.

We are a young heat pump technology company from Cologne. With a great mix of young and old and a modern, open team culture, we make craftsmanship sexy and rely on the best and most ambitious talents! While others continue to ride the dead horses of gas and oil heating, or dream of hydrogen and district heating, we focus 100% on heat pump technology.

Our goal is to make green heating feasible & affordable for everyone. We offer our customers an all-round carefree package for their heating system change, from the application for funding to installation and subsequent support during operation. Best of all, our subscription model eliminates the purchase costs and risks of buying!

All Vamo heat pumps are digitally networked in real time. This allows us to respond to malfunctions before they occur. And: we can remotely control the systems so that our customers have minimal electricity costs. The intelligent interaction of all heat pumps in our fleet also helps to keep our electricity grid stable.

Together with you, we want to digitalize the trade and make it more attractive for young people and thus help the heat and energy transition in Germany to achieve a breakthrough.

Heat your home, not the planet!
