Job description

Задачи:

You’ll design and build the parts of the platform that run Grundversorgung and the processes around it in Germany: contract and supply-status logic, billing and pricing rules, dunning and disconnection flows, and the market communication that ties it all to network operators and metering point operators. You’ll work in a small, autonomous team with product managers and domain experts, owning features from design to production. Build and evolve the German supply domain on the platform: implicit contracts on move-in, Ersatzversorgung and Grundversorgung states and transitions, supply start/end, move-out, termination and special termination rights. Implement billing and pricing logic — general tariffs and price changes with notification deadlines, Abschläge, periodic and final invoices, taxes, levies and Konzessionsabgabe — so it’s correct, auditable and easy to change when regulation does. Build market communication flows for GPKE / GeLi Gas, WiM and MaBiS: processing and generating EDIFACT messages (UTILMD, MSCONS, INVOIC, REMADV, APERAK, CONTRL), mapping Prüfidentifikatoren to domain events, and keeping up with BDEW format releases. Automate exceptions — rejected registrations, missing meter readings, switching conflicts, disconnection orders — so operations teams handle fewer cases by hand. Turn regulation into code together with domain experts: model the rules explicitly, write tests that encode them, and design for frequent change. Own your work in production — monitoring, debugging live issues with real customer impact, and improving reliability and performance at scale. Raise the bar through code review, pairing and sharing domain knowledge across teams.

Требования:

Hands‑on engineering experience on German Grundversorgung processes — you’ve built or maintained systems for a Grundversorger, an energy supplier or a utility platform, and can explain how Grundversorgung and Ersatzversorgung differ in data and logic. 3+ years of professional software development, with a strong backend focus. Working knowledge of German market communication (GPKE / GeLi Gas, WiM, MaBiS) and EDIFACT message handling. Experience with billing or contract systems in the energy sector. Solid fundamentals: clean domain modelling, relational databases, testing, and working in a collaborative codebase. Comfortable working in English; German is a strong advantage, since much of the domain material and client contact is German. Python and Django (the core of the platform’s backend), PostgreSQL, GraphQL, AWS. Experience migrating a German utility’s customer base between systems (e.g. from SAP IS-U, Schleupen or Wilken). Exposure to smart metering (iMSys, MsbG), §14a EnWG or dynamic tariffs. Experience with event‑driven or message‑based integration and high‑volume batch processing (billing runs, message processing).
