ITM Power Systems Engineer interview questions & guide 2026

Our interview process is designed to evaluate both your deep technical proficiency and your ability to thrive within the collaborative culture of ITM Power. The following questions represent common themes observed in our selection process.

Technical and Process Engineering

These questions assess your foundational knowledge of process design, system integration, and your ability to apply engineering principles to real-world hydrogen electrolysis scenarios.

• How do you approach the scaling of a pilot-level process to a commercial-scale system?
• Can you explain your experience with P&ID development and process safety management?

Preparation for ITM Power requires a shift from theoretical knowledge toward practical application. You should prepare to articulate not just what you know, but how you have applied that knowledge to deliver tangible results in previous projects.

Role-related knowledge – We look for a deep understanding of process engineering, specifically within the context of electrochemical or high-pressure gas systems. Be prepared to discuss specific technologies, materials, and safety protocols you have worked with in your career.

Problem-solving ability – You will be evaluated on your ability to break down complex, multi-faceted engineering challenges into manageable steps. Success here involves showing your work—explain your logic, the assumptions you made, and how you validated your design choices.

Collaboration and Communication – As a Systems Engineer, you will act as a hub between various departments. We look for candidates who can explain highly technical concepts to non-technical stakeholders and who can effectively manage cross-functional relationships to keep projects on track.

The interview process at ITM Power is structured to be rigorous yet transparent. It typically begins with an initial screening to gauge your technical background and alignment with our mission. This is followed by a series of deeper technical discussions and, where appropriate, a final round involving team leads or management.

We prioritize a balanced assessment of your technical depth and your cultural fit. Our interviewers look for a "hands-on" mindset, curiosity, and a commitment to safety and quality. The pace is generally brisk, reflecting the fast-moving nature of the green energy sector, and you can expect a high level of engagement from your future colleagues throughout the process.

This visual timeline tracks your progression from the initial contact to the final decision. Candidates should use this as a roadmap to pace their preparation, ensuring they are ready for technical deep-dives early in the process while keeping their behavioral examples refined for later stages. Note that the specific number of rounds can vary based on the seniority of the role and the specific team location.

Process Optimization and Safety

This area is critical because the reliability of our hydrogen systems is non-negotiable. We look for engineers who integrate safety into the design phase rather than treating it as an afterthought.

Be ready to go over:

• P&ID and Process Flow: Your ability to draft and interpret complex system schematics.
• Safety Standards: Familiarity with HAZOP, SIL, or equivalent safety assessment methodologies.

As a Process and Systems Engineer, your primary objective is to drive the integration of our electrolysis systems. You will lead the development of system architectures, ensuring that every component—from fluid handling to control interfaces—is optimized for performance.

You will work closely with the R&D, production, and field engineering teams to translate innovative concepts into robust, repeatable systems. This includes driving technical documentation, overseeing system testing, and participating in the commissioning phases of our projects. Your ability to anticipate technical risks and mitigate them early in the design cycle is a key driver of your success.

A successful candidate at ITM Power brings a blend of specialized engineering expertise and a proactive, problem-solving mindset.

• Must-have skills:
  • Degree in Chemical Engineering, Mechanical Engineering, or a related field.
  • Demonstrated experience in process design and system integration.
  • Proficiency with industry-standard engineering software for modeling and design.
  • Strong understanding of process safety and quality control standards.
• Nice-to-have skills:
  • Experience in the hydrogen, energy, or electrochemical sectors.
  • Knowledge of automation and control systems (PLC/SCADA).
  • Proven track record of managing projects from design through to commissioning.

Q: How long does the hiring process typically take? A: While timelines vary by project urgency and candidate availability, we strive to move efficiently. Most candidates complete the process within four to six weeks.

Q: What is the company culture like? A: ITM Power is a fast-paced, mission-driven environment. We value innovation, collaboration, and a "can-do" attitude toward solving the world’s most pressing energy challenges.

Q: Is there flexibility in work location? A: Our positions are generally site-based or hybrid depending on the specific team needs in Berlin or Linden. We prioritize being close to the hardware and the teams building it.

• Show your work: When answering technical questions, don't just give the answer; explain the "why" and "how" behind your logic.
• Understand the mission: Research our specific technology stack and the role of green hydrogen in the energy transition. Enthusiasm for our mission is highly valued.
• Prepare for ambiguity: In the clean energy sector, you will face new challenges. Demonstrate how you navigate uncertainty by leveraging data and logical frameworks.
• Ask meaningful questions: Use your time at the end of the interview to ask about the specific engineering challenges the team is currently facing.

The role of Systems Engineer at ITM Power is an opportunity to contribute directly to a more sustainable future. By focusing on your technical proficiency, your ability to integrate complex systems, and your commitment to safety, you will position yourself as a strong candidate.
