About BlueHeart Energy

BlueHeart Energy was founded in 2016 as a deep-tech company that has developed a new sustainable thermoacoustics technology to radically improve the performance of heat pumps, enabling them to evolve from being the best solution in the market to becoming the perfect solution. Our technology is a disruptive approach to generate heat and cold, with potential to revolutionize the whole industry.

With our so called 'Blue Heart' inside, heat pumps turn into affordable, silent and flexible devices, capable of working with wide temperature ranges suitable for both new and existing houses. Importantly, BlueHeart doesn't require any refrigerants and doesn't generate any CO2e emissions.

About the Role

As a R&D Electrical Technician at Blue Heart Energy, you support the Testing Team by maintaining and improving our laboratory test infrastructure. You work across several laboratories, each dedicated to testing different machines and configurations, as our heat pump system is composed of multiple components, each with its own specific test setup.

As we are in an active development phase, test benches and experimental systems are frequently modified, improved, and adapted. The Lab Technician plays a key role in assembling, repairing, and troubleshooting these systems to ensure reliable and safe operation. This role requires a strong hands-on mindset and the ability to work efficiently in a fast-changing R&D environment.

You will work with a wide range of technical systems, including plumbing and hydraulic circuits (pipes, valves, pumps, water/glycol loops, flow and pressure sensors) as well as electrical and electronic systems (PCBs, wiring, cables, connectors, and sensors).

In addition, you will contribute to the design, construction, and commissioning of new test benches, including mechanical assembly, plumbing, electronics, and sensor integration.

Testing activities involve pressurized systems, so the Lab Technician is responsible for ensuring safe laboratory operations and strictly following safety procedures and instructions. The Testing Team is at the heart of research and development and works in close collaboration with the R&D, Engineering, and Controls teams to continuously improve our testing capabilities.

What You'll Do

• Your day-to-day will typically include: 40% of troubleshooting the test benches and the units; 50% of building new test benches; 10% of documentation report & bug tracking.

• Support the daily operation of laboratory test benches and experimental machines.

• Assemble, modify, and maintain plumbing and hydraulic systems (pipes, valves, pumps, water/glycol circuits).

• Build, wire, and troubleshoot electrical and electronic systems (PCBs, sensors, cables, connectors) on the test bench side.

• Perform troubleshooting and repairs on test benches and machines to minimize downtime.

• Participate in the design, construction, and commissioning of new test benches.

• Install, calibrate, and replace sensors and instrumentation (flow, pressure, temperature, etc.).

• Work closely with engineers to adapt and improve test setups as development evolves.

• Ensure safe and reliable lab operations, following internal procedures and best practices.

• Document modifications, issues, and improvements to test systems when required.

• Solving issues with the team, conducting root cause analyses, and implementing sustainable solutions.

• Collaborate with internal teams to ensure all stakeholder needs are met and that solutions align with defined requirements.

What We're Looking For

• At least 3 years of working experience is required.

• Good communication skills and ability to work independently while collaborating closely with engineers and technicians.

• Hands-on experience with plumbing and hydraulic systems (pipes, valves, pumps, water/glycol circuits) or strong motivation to learn and develop these skills.

• Experience with electrical and electronic systems (basic electronics, PCBs, wiring, cabling, connectors).

• Capable of understanding, interpreting, and producing technical documentation, including electrical/electronic schematics and mechanical drawings, and updating them to reflect hardware modifications.

• Ability to assemble, modify, and repair test benches and experimental setups.

• Strong troubleshooting skills for mechanical, hydraulic, and electrical systems.

• Experience working with sensors and instrumentation (flow rate, pressure, temperature, etc.).

• Comfortable working in a fast-paced R&D environment.

• Practical, solution-oriented mindset with a "hands-on" approach.

• Good organizational skills and attention to detail to ensure safe and reliable lab operations.

• Startup mentality: ownership, adaptability, and initiative.

• A passion for sustainability, clean tech, or environmental innovation is important to us! We are revolutionizing the industry and are eager to have other passionate colleagues join us in this mission.

What We Offer

• Salary range between € 3.5000 - € 4.300 monthly gross depending on experience.

• Opportunity to participate in the company's ESOP, directly linked to company value creation and individual performance.

• 25 vacation days.

• Hybrid work arrangement supporting autonomy and work-life balance.

• Tailored learning and development opportunities to support your continued growth.

• Access to OpenUp, because we prioritize mental well-being.

• Participation in our pension scheme with employer contribution.

• Commuting allowance, in line with our travel policy.

• A strategic role in a purpose-driven scale-up, contributing to a greener world and shaping the future of sustainable thermal technology. Learn more about our mission here .
