Project description:

You will join the development of an advanced digital twin platform for the energy transition, designed to unify energy and climate-related data into a single, comprehensive solution.

The platform supports stakeholders involved in energy transformation by providing data-driven insights and decision-making tools. It addresses key challenges such as CO₂ balancing, renewable energy expansion, power grid planning, and municipal heating strategies.

Built on a modular and scalable architecture, the solution enables complex analytics and supports real-time insights in a rapidly evolving energy sector.

Main responsibilities:

• Design, develop, and maintain scalable backend services using TypeScript/Node.js as the primary technology stack

• Build and optimize PostgreSQL data models and queries

• Develop and maintain APIs using gRPC and REST

• Containerize applications with Docker and manage deployments on Kubernetes (AWS)

• Ensure system scalability, performance, and reliability

• Collaborate with frontend (Angular) and backend (NestJS) teams

• Participate in agile ceremonies, code reviews, and continuous improvement initiatives
