At Voltmasters we are building the future of energy management. Our Energy Management System (EMS) helps companies intelligently control their battery systems, solar energy and consumption. We connect industrial hardware, real-time data and AI to make sustainable energy genuinely efficient.
We are a young and ambitious tech company with solid growth plans. As a software engineer you work across the full stack on a product that accelerates the energy transition.
What you will do
- You build features that control and monitor our smart devices, from backend to interface.
- You work with real-time data streams via MQTT, InfluxDB and AWS.
- You translate complex energy processes into reliable, scalable software.
- You help shape architecture, user experience and performance.
- You work closely with our embedded, backend and frontend engineers.
What we expect
- You have experience with modern web technology and feel at home in a full-stack environment.
- Knowledge of PHP (Laravel), JavaScript or a comparable stack.
- You write readable, structured and well-tested code.
- You enjoy thinking about product decisions and technical strategy.
- You communicate clearly and collaborate well in a team.
Extra points if you have experience with IoT, energy projects or cloud infrastructure, but enthusiasm and a willingness to learn matter just as much.
What we offer
At Voltmasters we believe that strong people make the difference. That is why we offer an environment in which you can grow, build and learn.
- A full-time role in a stimulating environment.
- A competitive salary package with tailored benefits (such as an internet allowance, meal and eco vouchers).
- Health insurance.
- An Apple laptop with a second screen, and a recent iPhone or Android smartphone.
- A noise-cancelling headset to stay in your flow.
- All the software you need to do your job well.
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.
Interested?
We do not have a long application process: show us your code. To get a good picture of what you can do, we would love to see some of your work. We do not expect your code to be perfect, but we do expect you to be honest about your experience and skills.
When you apply, send us:
- A link to your GitHub profile or open-source contributions.
- No public code? Then send a small project that shows what you can do: a hobby project or a simple app that fetches data from an API and stores it in a database.
