Mechanical Commissioning Engineer — Onsite Role | £450-£500 per day | 4-Month Contract

We are seeking an experienced Commissioning Engineer to support a busy data centre project through a peak delivery phase. This is a boots-on-the-ground role — you'll be out in the field all day commissioning and tagging, with minimal office time.

Start: Beginning of October (potential to start earlier)

Duration: 4 months (project delivery through end of January)

Location: Onsite

Rate: £450-£500 per day (outside IR35)

Responsibilities

• Hands-on commissioning, tagging, and walkdowns (W2).
• QA/QC checks as part of walkdowns.
• Working closely with the Commissioning Manager (who will handle documentation and project push).
• Focused on systems including Generators, UPS, Busbars, and related critical infrastructure.

Requirements

• Proven commissioning experience across L1 to L3 stages.
• Strong background in mission-critical / data centre environments.
