Senior Software Engineer (Fullstack) (f/m/x) - Metrify Smart Metering

We are Metrify Smart Metering, Germanys largest competitive smart metering operator, and a new strategic spin-off initiative by Enpal.

Are you ready for one of the great infrastructure challenges of the 2100s? To truly transform into a decentralized power grid that can support a fully electrified, renewable future, millions of homes need to be equipped with smart meters and control systems. Thats why we are performing the fastest smart meter roll-out in the German market at unprecedented scale, shaping the way this digitally transformed grid will operate. Our mission is to enable utilities, grid operators, and energy providers to install and operate smart meters. Our service portfolio covers all aspects of metering operations: from electricity meter installation and market communication to data management and clearing.

While Metrify emerged from Enpal, we now operate independently in the market, serving a broad range of commercial customers, energy suppliers, and municipal utilities.

Job Description

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. Youll design and implement reliable backend services, integrate with key external platforms, and contribute to intuitive frontend experiences.

Responsibilities

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

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

Workflow & Business Rules: Youll 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).

Code Quality & Testing: Youll maintain best practices in unit testing, code review, and continuous integration.

Performance & Reliability: Youll monitor and optimize service performance and troubleshoot complex issues across multiple environments.

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

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

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

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

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

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