Role description

As our new Process Engineer, you will play a key role in designing and developing the process equipment for our electrolysers. You will work to improve product performance and ensure safe, reliable, and efficient electrolyser systems. This is a broad and hands-on role, ideal for someone who enjoys working closely with engineering in a small company where you can make an impact.

You will be based at our Gothenburg office.

Key Responsibilities

• Generate process flow diagrams (PFDs) and piping and instrumentation diagrams (P&IDs), as well as perform mass and energy balance calculations and prepare equipment specifications
• Create, maintain and update process documentation, including cause-and-effect matrices, process description and operating manuals
• Ensure compliance with applicable safety standards, regulatory requirements and quality requirements
• Perform dimensioning and sizing of process systems, including piping, pressure safety valves (PSVs) and control valves
• Design and develop water and gas purification systems for electrolysers
• Support equipment selection such as instruments, valves and filters
• Participate in commissioning and validation activities, including Factory Acceptance Tests (FAT) and Site Acceptance Tests (SAT)

Your profile

You have a Bachelor’s degree in process engineering, chemical engineering, mechanical engineering, industrial engineering or another relevant technical field together with 5+ years of relevant experience in a process engineering role. Your background includes:

• Experience with pressurized equipment
• Experience working with flammable gases
• Strong understanding of process optimization, quality tools, root-cause analysis and risk assessments (e.g., FMEA, HAZOP, HAZID, 5 Whys)
• Familiarity with pressure equipment codes/standards (e.g., PED, ASME, ATEX, IEC 61511, IEC 62061, ISO 12100)
• Experience working with technical documentation
• Fluent English is a must

You are a team player who promotes an environment of respect, transparency and tolerance ensuring strong and positive relationships with colleagues. Being a young and innovative company, we believe that curiosity, drive and being self-motivated are important qualities.

You enjoy solving problems independently and feel comfortable with quick decision-making and changing priorities.

We are looking for a practical person with strong analytical skills and the ability to work effectively in a small, cross-functional team.
