Job Summary
We are seeking an experienced C&Q / Shakedown Engineer to support commissioning activities on a large-scale, high-profile biopharma project. This role will focus on the hands-on execution, optimisation, and stabilisation of upstream and downstream bioprocessing systems, working closely with C&Q Leads, Automation, and cross-functional project teams.
The project centres on the commissioning and qualification of bioreactor systems, ranging from small-scale development units to large commercial-scale operations, alongside supporting process equipment including CIP/SIP, chromatography, filtration, and buffer systems. The role will involve system setup, shakedown, and performance tuning to ensure equipment operates reliably and meets Good Engineering Practice (GEP) standards prior to qualification.
This is a technically demanding, site-based role requiring strong troubleshooting, coordination, and problem-solving capabilities. It is ideally suited to senior-level engineers with proven experience in commissioning complex biopharma systems and driving systems from mechanical completion through to stable operation and handover.

- Troubleshoot and resolve complex technical issues, including misalignments, leaks, control instabilities, and equipment or instrumentation faults.
- Ensure all shakedown and commissioning activities are executed in accordance with GEP requirements and site safety procedures, including COHE/LOTO where applicable.
- Coordinate closely with Automation Engineers (e.g. DeltaV/PLC) to support interlock testing, I/O verification, and alarm functionality during system start-up.
- Interface with Utilities, HVAC, vendors, and construction teams to ensure effective integration and issue resolution across system boundaries.
- Support commissioning documentation, including test records, punch list management, and system turnover packages to C&Q teams.
- Provide technical support and guidance to junior engineers and technicians during commissioning and shakedown activities.
- Support deviation resolution, field changes, and issue tracking to ensure systems are delivered in line with project timelines and quality expectations.
Qualifications
- Degree in Engineering, Biotechnology, Pharmaceutical Sciences, or related discipline
