En Voltmasters nuestro Energy Management System (EMS) conecta miles de dispositivos: baterías, inversores, contadores y puntos de carga. Esto genera un flujo continuo de datos de energía en tiempo real. Como Data Engineer construyes los pipelines que convierten ese flujo en una base fiable y utilizable para toda la plataforma.
Trabajas en la intersección del hardware, la nube y la IA, sentando las bases sobre las que funcionan nuestros algoritmos y dashboards.
Qué harás
- Construir y mantener pipelines de datos que procesan los datos de sensores y contadores mediante MQTT, InfluxDB y AWS.
- Modelar datos de series temporales y velar por la calidad, la fiabilidad y la escalabilidad.
- Poner los datos a disposición de nuestros modelos de ML, dashboards e informes.
- Optimizar el almacenamiento y el rendimiento de las consultas para grandes volúmenes de series temporales.
- Colaborar estrechamente con backend, ML y producto para convertir los datos brutos en información concreta.
Qué esperamos
- Tienes experiencia construyendo pipelines de datos en Python y SQL.
- Conocimientos de series temporales o streaming (Kafka, MQTT) y de bases de datos (InfluxDB, PostgreSQL).
- La experiencia con la nube (AWS) e infrastructure-as-code es un gran plus.
- Escribes código limpio, testeado y bien documentado.
- Un interés por la energía, el IoT o la sostenibilidad es un plus.

Personal development
At Voltmasters there is a strong mindset of continuous growth. Standing still is moving backwards. We encourage everyone to keep learning, experimenting and sharing knowledge.
- Stay current: every week we set aside time to explore or experiment with new technologies.
- Learning budget: each year you get an extra budget of €2,000 to invest in personal growth, for books, training or conferences.
- A healthy balance: we aim for a good work-life balance. No overtime, but flexibility and room to recharge.
- Learning together: we share knowledge through internal sessions, reviews and team lunches.
- Autonomy and trust: you get the freedom to learn and grow at your own pace, within a team that strengthens each other.
Extras that will quickly feel familiar
- Hybrid working: work from home or from our office space in Gistel.
- Freedom and trust: few rules, lots of responsibility.
- Small teams, big impact: direct influence on product decisions.
- Flat structure: no layers of management, just people working together.
- Daily lunches together and the occasional afterwork.
- Unlimited drinks and fruit at the office.
We are still small enough to be flexible, but big enough to make an impact.
