Job Description

Apply now Apply now Alquion is looking for a Commissioning & Testing Engineer We are a Dutch cleantech scale-up based in Rotterdam’s port and Eindhoven’s Brainport, born from the merger of Battolyser Systems and VDL Hydrogen Systems. Our mission is to turn low-cost solar and wind energy into affordable hydrogen that powers industry sustainably. Our Flexolyser™ is the first fully flexible pressurized alkaline electrolyser for industrial use. It switches on and off with volatile power prices, producing hydrogen when electricity is cheap and supplying the grid when prices are high. By combining innovative design with decades of manufacturing experience, we help secure Europe’s energy independence and build a competitive, net-zero industry. Want to make a real impact at a fast-paced scale-up? Join our international team of bright colleagues from leading companies and institutes. About The Role As a Commissioning & Testing Engineer, you will be part of the Testing & Validation Team. Your base is our Eindhoven office, but you’ll spend much of your time at our client sites in Budel and Eindhoven. As we develop our Flexolyser for the market, we deploy increasingly bigger systems at customer locations. Your role is to get these systems running and prove that they work: from hands-on commissioning of the Balance of System (BoS) and electrolyser stacks to developing and running the experiments that follow. Commissioning is only the start; once a system is ready, the actual testing begins, and you will be at the heart of it. You will start with our 500 kW Demonstrator, working closely with your fellow Testing & Validation engineers, the engineering team and interface with the customer and suppliers. After start-up, you will take on the operation and upgrades of the systems. As our multi-MW industrial system further develops, your focus will shift towards its commissioning. What We Offer We work in an innovative environment with an international team of people coming from different industries, now all invested in making our technology work. We offer you a position in which you will have an important contribution to our mission to ‘Secure Europe’s Energy Future’, including the following: A competitive salary, ranging from € 4.000 - € 5.500 gross per month (medior position) 27 leave days Pension scheme, with a 15% contribution, 50-50 split by employer and employee Holiday allowance of 8%, paid out monthly Travel allowance of € 0,23 cm/km with green mobility (and € 0,16 cm/km for fuel based) Training budget Laptop and iPhone Contributing directly to the energy transition and help commercialize innovative technology Mentorship from experienced professionals A lot of autonomy and freedom to have ownership of your role. You will work with an international team of fun and bright colleagues with professional backgrounds in various top companies and institutes, check us out on LinkedIn.

Troubleshoot mechanical, electrical, instrumentation and control issues and drive them to a solution Support the Project Engineer with site coordination: punch lists, mechanical completion and handover Implement, commission and test system upgrades throughout the lifetime of our systems. As our multi-MW system is further developed and designed, shift your focus towards preparing and executing its commissioning Feed lessons from testing and operation back to engineering to improve performance and reduce cost of future systems About You You are a hands-on engineer who enjoys being in the field and getting equipment to work. A mechanical, chemical, electrical or process engineering (or similar) degree, HBO/WO. 2-5 years of relevant experience in commissioning, testing or operation of process installations in the chemical, oil and gas, metallurgical industries (or similar). Proven ability to work safely in a chemical or industrial environment, including working with hazardous substances, permit-to-work systems and safety procedures.
