Mechanical Commissioning Lead – Client Side
Cardiff | 8-Month Contract | All-In Rate | Prestigious Client
We are working with a prestigious client on a major, high-profile project in Cardiff and are looking for an exceptional Mechanical Commissioning Lead to join the team for an 8-month assignment.
This is a client-side leadership role for an experienced commissioning professional who can take ownership of the mechanical commissioning strategy through the final and most critical stages of the project.
The project is currently approaching the tail end of Level 3 commissioning, so we are specifically looking for someone with a strong track record in L4, L5 and IST commissioning who can step in, provide leadership and drive the project through to successful completion.
The Role
As Mechanical Commissioning Lead, you will take a senior position within the client's commissioning team, working closely with the CXA Project Manager, Account Lead and General Contractor to ensure the remaining commissioning programme is delivered safely, effectively and to the required standards.
You will be responsible for providing strong technical and managerial oversight across the mechanical commissioning process, with a particular focus on L4/L5 testing and Integrated Systems Testing (IST).
This is a role where you will need to be comfortable operating at both strategic and delivery level — challenging the GC when required, coordinating multiple stakeholders and ensuring the commissioning programme remains on track.

- Identify commissioning risks, gaps and programme constraints and drive them through to resolution.
- Coordinate with the GC, specialist subcontractors, vendors and wider project stakeholders.
- Provide clear reporting on commissioning progress, risks, issues and readiness.
- Maintain a strong focus on quality, safety, documentation and handover.
- Ensure commissioning activities are delivered in line with the client's expectations and project requirements.
- Provide strong leadership and technical challenge throughout the final stages of the project.
About You

You will need to demonstrate:
- Strong mechanical commissioning background.
- Proven experience leading L4, L5 and IST commissioning.
- Previous experience operating in a client-side commissioning role or in a senior commissioning leadership position.

- Excellent communication and stakeholder management skills.
