Test Engineer

Role overview:
 

We're looking for an experienced and hands-on Stack Test Engineer to join our Stack Development team at Stargate Hydrogen. This role focuses on designing, building, assembling, and testing experimental systems and components to support the development of next-generation electrolyser stacks. 

You will work at the intersection of engineering and practical execution - turning concepts into 3D models and drawings that can be turned into physical prototypes. Additionally, you will be responsible for setting up test rigs and supporting experimental campaigns. While the work is highly hands-on, it requires an engineering mindset, attention to detail, and the ability to understand and improve technical systems. 

A significant part of the work is carried out within structured R&D and grant-funded projects, requiring disciplined documentation, reproducible results, and alignment with technical milestones and reporting requirements. The role combines hands-on execution with an understanding of how experimental work contributes to broader product development, validation, and research objectives. 

About the company:
 

At Stargate, you will be part of a team determined to change the world. We are passionate about climate, hydrogen and innovation

Our enthusiastic team and pioneering spirit offer the opportunity to work with real purpose. We encourage you to think big and outside the box to bring your ideas to life

Being in a scale-up phase, the company will enable you to shape its structure and processes and give you significant responsibility and freedom in your work. The environment is agile, and problems are solved in an unbureaucratic way.  

What does day-to-day look like in this role?
 

• Experimental Assembly & Prototyping 

Build, assemble, and modify experimental stack components, test rigs, and supporting systems. Work with mechanical parts, piping, fixtures, and custom setups in a workshop/production environment. 

• Testing & Validation Support 

Execute test procedures, prepare setups, and support test campaigns. Monitor equipment, collect data, and ensure tests are conducted safely and consistently. 

• Design in CAD 

Design stations, jigs for building/testing stacks, and serial/prototype stack components. 

• Drawings: Create drawings in CAD software for prototype manufacturing 

• Workshop & Equipment Operation 

Operate industrial tools and equipment (e.g. torque tools, presses, basic machining tools). Handle pressure-related components and hardware safely and carefully. 

• Continuous Improvement & Troubleshooting 

Identify issues during assembly or testing, propose improvements, and implement practical solutions together with engineers. Provide feedback from hands-on work to improve designs. 

• Basic System Integration 

Support the setup of simple control systems for test benches (sensors, actuators, wiring). Assist in integrating mechanical and basic electrical components. 

• Documentation & Reporting
  

Document assembly steps, test setups, and experimental results in a structured and traceable way, supporting R&D activities and technical reporting where required. 

Must-have qualifications:
 

• Technical education (vocational or higher) in mechanical engineering, industrial engineering, or similar 

• 3+ years of hands-on experience in industrial environments (e.g. manufacturing, assembly, testing, maintenance) 

• CAD skills (e.g. Inventor or similar) 

• Strong practical skills with tools, mechanical systems, and industrial equipment 

• Experience working with structured processes and safety standards 

• Ability to read technical drawings and follow engineering instructions 

• Engineering mindset with problem-solving attitude 

• Experience working with defined processes, timelines, and deliverables in industrial or R&D environments 

• Good communication skills in English 

Nice-to-have qualifications: 

• Experience with pressure equipment or piping systems 

• Forklift license 

• Experience with 3D printing, CNC, or workshop fabrication tools 

• Ability to assemble and troubleshoot simple electrical/control systems 

• Experience with test rigs or laboratory equipment 

• Familiarity with hydrogen, chemical, or process industry environments 

• Understanding of safety standards related to industrial or pressure system
  

• Experience working in grant-funded, research, or highly structured R&D environments (e.g. EU projects, IPCEI, Horizon Europe) 

Why us?
 

• You will join a world-class team of 65+ experienced and goal-driven professionals and hydrogen
  technology experts.
  

• We are an agile scale-up wishing to make a difference in a field typically dominated by large and
  slow behemoths.
  

• We have secured a €29m state aid via the Important Projects of Common European Interest (IPCEI) framework, and are backed by our existing investors such as UGI and Repsol.
  

• The performance of our ceramic electrode technology has been independently validated by Fraunhofer IFAM in Dresden, and the performance of our prototype stack by ZSW in Stuttgart.

What’s in it for you?
 

• You will be able to contribute to electrolysis technology and its novel applications, thereby participating in creating a net-zero world.
  

• You can accelerate your career and enjoy professional growth opportunities.
  

• While this is primarily a hands-on, onsite role, we offer flexibility where the nature of the work allows. 

• You can choose between employer health insurance or sports compensation.
  
• We organise regular team events and company Summer Days that foster camaraderie, collaboration, and fun outside of the workplace.
   

We are seeking candidates located in EU.

We aim to fill this position at the earliest opportunity and latest by the end of August 2026, so we encourage interested candidates to submit their applications promptly.
