In most cases, a degree in a relevant field such as electrical, mechanical, or civil engineering is needed. Additionally, industry/ on-site experience such as an internship or apprenticeship — is highly valuable, helping to develop technical and practical skills.
Career progression in commissioning engineering can take many routes, including:
- Senior Commissioning Engineer – Handling more complex projects and leadership responsibilities.
- Commissioning Manager – Overseeing commissioning teams and projects.
-
Project Engineer/Manager– Managing broader engineering projects, including design and implementation.

Key Responsibilities of a Commissioning Engineer
Unlike traditional office-based roles, Commissioning Engineers in life sciences and data centres work on-site, whether in biotech research facilities, pharmaceutical production plants, or high-performance computing environments. This hands-on role involves testing, validating, and optimising critical systems—ensuring laboratory equipment, bioprocessing machinery, or data centre infrastructure functions precisely and reliably.
Beyond practical implementation, engineers must review complex technical documentation, conduct system performance evaluations, and generate reports to ensure compliance with industry standards and regulatory requirements. A deep understanding of life sciences protocols, high-throughput computing, and environmental controls is essential for interpreting technical diagrams and project specifications accurately.
Success in this role requires a balance of independent problem-solving and collaboration with cross-disciplinary teams, including researchers, facility managers, and data specialists. Effective communication is crucial—whether explaining system diagnostics, implementing safety measures, or updating stakeholders on commissioning progress.
As with most field-based engineering roles, challenges arise that demand innovative, real-time solutions, often in high-stakes, regulated environments. This career calls for technical expertise, adaptability, and a precision-driven, solution-oriented mindset to ensure seamless operation of critical infrastructure in life sciences and data centres.
How to Prepare for a Commissioning Engineer Role
Given the mix of technical and practical skills required for this role, thorough preparation is essential. Before an interview, ensure you have:
- Researched the company and its projects – Understanding their focus will provide insight into the role's requirements.
- Prepared to discuss your experience – Be ready to explain previous projects that demonstrate transferable skills.
