What you will do

Exciting opportunity

You are a key member of Solhyd’s product development team, working closely with hardware engineers and the automation engineer to build and maintain the software and firmware that powers Solhyd’s products and setups.Your key responsibilities are:

• You are the responsible engineer for this domain and work directly with the product development team to shape functionality and safety from concept to field deployment.
• You design and implement firmware for embedded systems including OS-level configuration and adaptation.
• You communicate with external parties when needed for hardware development.
• You develop and maintain process control software: setting up control loops, sensor integration, actuator interfaces, and safety interlocks.
• You implement and maintain finite state machines (FSMs) to manage operational modes, startup sequences, error handling, and shutdown procedures of Solhyd’s products.
• You develop communication protocols and data pipelines between hardware components, gateway devices, and backend systems (e.g. MQTT and Modbus).
• You write clean, maintainable, and well-documented code; you set up version control practices and contribute to a professional software development workflow.
• You perform software testing, debugging, and validation to ensure reliable performance in both lab and field conditions.

Maintenance and development of the online monitoring platform

• You ensure continuous availability and reliability of the Grafana monitoring page used by the team and clients.
• You update and extend the backend : adding new data sources, building new reporting views, or adapting dashboards to evolving needs.

Maintenance of equipment and test setups in research, product development, and commercial panels in the field.

• You support troubleshooting and software-related interventions on lab setups and field-deployed panels, working hands-on alongside the automation engineer.
• You keep setups running reliably, identifying software or firmware issues, and implementing fixes in a timely manner.

Who you are

• You hold at least a bachelor’s degree in computer science, electrical engineering, mechatronics, embedded systems, or an equivalent field.
• You have at least 5 years of experience in software and/or firmware development. Given that you will be the sole engineer responsible for this domain, you must be able to operate independently and make well-founded technical decisions without day-to-day supervision from a senior firmware engineer.
• Python experience is a must
• Proficiency in C and/or C++ is highly valued
• Fluency in Dutch & Englishis required
• You have experience with embedded systems, real-time control, process automation, or industrial IoT.
• Familiarity with monitoring and visualization tools such as Grafana, InfluxDB, or similar data backends is a plus.
• Knowledge of or interest in AI and machine learning techniques is a plus.

What we do for you

We offer an exciting position at the forefront of technology development. You will join an amazing team, start every day with a smile, and contribute to the growth of this new hydrogen module technology

We are looking forward to welcoming you to our unique office, situated in a farm complex that has been transformed into a center for circular bio- economy (Bijzondereweg 12, 3360 Bierbeek, Belgium). We're expecting to move to our new site in Kortenberg in summer 2027.

At Solhyd we give everyone a fair chance. We are looking for skilled and motivated people. We’re looking for people who enjoy building things together. People who speak openly, listen to each other, and care about making a difference.
