Senior Software Engineer (Backend & Integrations) (f/m/d) - Metrify Smart Metering

Company Description

We are Metrify Smart Metering, Germany’s 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. That’s 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. 

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. You will be reporting directly to the CTO. This role is hybrid in Berlin. 

Job Description

We are looking for a Senior Software Engineer (f/m/d) to join Metrify Smart Metering and take end-to-end ownership to develop mission-critical services, data workflows, and third-party integrations. You will work closely with the team to deliver highly available APIs, custom logic for data transformations, and seamless integrations with key systems like CRMs, WFM, and more that will be the foundation for further product development. You will drive both what needs to be built and how to build it, turning shared ideas into working solutions, with full ownership from idea to deployment.  

Responsibilities 

1. Backend Architecture: You’ll design and implement scalable APIs and services using languages like Python (Flask, FastAPI, DAF), TypeScript (Node.js), or C#.
2. Integration Development: You’ll connect and synchronize external systems (CRM, WFM, Wilken) with our internal data and business logic. 
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.

Qualifications

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 Python, Node.js, 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.
