Senior Software Engineer (Backend)(f/m/x) _metrify

Our goal is to have a solar system on every roof, a storage unit in every house, and an electric car in every garage. Enpal makes this possible with an integrated total solution for decentralized energy—from solar systems and battery storage to wall boxes, smart meters, and heat pumps. At the heart of it all is our AI-powered platform Enpal.One+, which intelligently connects thousands of systems and efficiently optimizes electricity procurement and feed-in on the energy market.

metrify is Enpal’s smart metering unit and the digital infrastructure for a smart energy ecosystem. With tens of thousands of iMSys units installed and scalable processes, we make energy measurable, controllable, and economically viable—and, together with our partners, we are laying the groundwork for new business models for the energy transition.

About the Team

You’ll be joining a brand-new 1.5 pizza team of engineers, working on projects from scratch. You will collaborate closely with non-technical stakeholders and the tech team. This role is hybrid in Berlin.

We are looking for a Senior Software Engineer (f/m/d) to join Metrify Smart Metering and take end-to-end ownership of building and scaling our core product systems. You’ll design and implement reliable backend services, integrate with key external platforms, and contribute to intuitive frontend experiences. You’ll collaborate with the team and stakeholders, helping drive product growth by shaping architecture and delivering product-ready solutions, owning the full lifecycle from idea to deployment.

What you’ll do

1. End-to-End Product Ownership: You'll build, implement, and own solutions end-to-end, collaborating closely with the team and directly with stakeholders to design, deliver, and iterate product features.

2. Fullstack Architecture: You’ll design and build reliable backend systems, integrating and synchronizing external systems (CRM, WFM, Wilken) with our internal data. You'll also contribute to frontend development to ensure seamless integration across the stack.

3. Workflow & Business Rules: You’ll partner with data engineers and platform engineers to develop or integrate rule engines and automation scripts that support device or data-driven operations (e.g., self-healing, auto-escalation).

4. Code Quality & Testing: You’ll maintain best practices in unit testing, code review, and continuous integration.

5. Performance & Reliability: You’ll monitor and optimize service performance and troubleshoot complex issues across multiple environments.

6. Mentorship & Knowledge Sharing: You’ll coach junior developers, foster a culture of clean code and innovation, and lead by example in technical discussions.

1. You gained solid experience in software development with a focus on backend systems, building distributed and high-availability services.

2. You are experienced in TypeScript/Node.js, Python, or C#, or you're a tech-agnostic, coming from a different background. Ideally, you have worked with RESTful API design, service-oriented architecture, and database interactions (SQL & NoSQL).

3. Familiarity with containers (Docker), cloud platforms (AWS, Azure, GCP), CI/CD pipelines, external APIs, or event-driven architectures is nice to have.

4. You communicate clearly in English. Knowledge of German is a plus.

5. You embody agile values and take ownership of identifying the problem, defining what needs to be built, and shaping the solution as it evolves. You're comfortable with ambiguity, move fast with MVPs, and keep a long-term architectural view in mind.
