Senior FrontEnd Developer

About us

Helicon builds software for energy companies and startups with energy-related products (e.g ABB, Polarium, Stockholm Exergi, Hitachi Energy). Our experienced software engineers and data scientists specialize in product development, data engineering, and cloud infrastructure.

A typical project includes some kind of data infrastructure (where we use tools like: Kubernetes, Airflow, PostgreSQL, TimescaleDB, InfluxDB, Kafka), a machine learning component (typically built around Spark and Tensorflow), APIs and software to facilitate communication between services (e.g. Python, FastAPI, Django, Kafka, RabbitMQ), and UIs where end-users can operate the system and visualize data and analyses (e.g. React, ThreeJS, WebGL). The front-end components of our systems vary from administration panels and analytical dashboards, to complex 3d-based digital twins.

Bonus
