About The Team

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. At Enpal MSB, we are performing the fastest roll-out in the German market at unprecedented scale, shaping the way this digitally transformed grid will operate.

Join our energetic and driven team as we turn our internal solutions into backbone infrastructure products to enable utilities, grid operators, and emerging energy providers to install and operate smart meters at scale. We achieve this by being a fast and independent unit built on interdisciplinary collaboration, where we work cross-functionally across technical and non-technical roles, putting a passion for the problems above traditional role boundaries.

Job Description

We are looking for a Senior Software Engineer to drive backend development for mission-critical services, data workflows, and third-party integrations. You will collaborate directly with non-technical stakeholders and the tech 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

• Backend Architecture: You’ll design and implement scalable APIs and services using languages like Python (Flask, FastAPI, DAF) or TypeScript (Node.js).
• Integration Development: You’ll connect and synchronize external systems (CRM, WFM, Wilken) with our internal data and business logic.
• 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).
• Code Quality & Testing: You’ll maintain best practices in unit testing, code review, and continuous integration.
• Performance & Reliability: You’ll monitor and optimize service performance and troubleshoot complex issues across multiple environments.
• Mentorship & Knowledge Sharing: You’ll coach junior developers, foster a culture of clean code and innovation, and lead by example in technical discussions.
  
  
  

Qualifications

• You gained solid experience in software development with a focus on backend systems, building distributed and high-availability services.
• You are experienced in Python or Node.js, and 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 are 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. You're comfortable with ambiguity, move fast with MVPs, and keep a long-term architectural view in mind.
