Project
The project is
a cloud-based SaaS platform hosted in Microsoft Azure that supports the management and optimization of district heating networks, heating substations, and other components of heating infrastructure. The application collects and processes data from meters, sensors, network measurements, and controllers, enabling remote monitoring, configuration, and control of connected devices. It
provides real-time and historical analysis of energy consumption and operational parameters, along with reporting, alerting, dashboards, maps, and data visualizations that help operators efficiently oversee entire heating networks. The platform also integrates with external data sources, such as weather forecasts and optimization systems, to improve operational efficiency and decision-making. The successful candidate will initially focus on modernizing and improving internal tools before moving into feature development and platform-related initiatives. The role
involves broad full-stack development across Node.js backend services and React-based frontend applications, working within a large, established codebase and contributing to solutions used in a distributed, cloud-native environment.
Expected competences and knowledge
- Understanding of safe data operations, including idempotency, handling partial failures, and minimizing operational risks
