A leading manufacturer in South Wales is looking for 2 contract Process Engineers to join their site engineering team on a 12-month basis. You will be part of a growing site undergoing significant investment, where your expertise will directly contribute to world-class manufacturing performance. The positions will be outside IR35 and offering an estimated hourly rate of £40 - £50 p/h, however this may be negotiable depending on the applicant's experience.

Commissioning:

• Plan and execute process aspects of commissioning, qualification, and validation activities such as pre-start checks, functional testing, water runs, chemical commissioning trials, and engineering batches according to the phased start-up timeline.
• Attend FAT and SAT, meticulously capturing reports and evidence for system turnover packs to ensure seamless transition between project phases.
• Support system-by-system turnover processes including walkdowns; define and close snag or punch lists as well as open-ends registers to meet agreed acceptance criteria.
• Drive closure of PSSR actions so that each Readiness Gate is achieved on schedule without compromising safety or quality standards.
• Develop and maintain isolation registers along with confirmed isolation schedules ahead of mechanical completion to ensure process safety during commissioning.
• Assist with dangerous substances inventory management and COMAH threshold assessment while maintaining pressure relief device registers with set-pressures, sizing basis, and certification documentation.
• Coordinate SIMOPS management during construction, commissioning, and operations windows by facilitating permits, isolations, and stop-work authority.
• Participate actively in Process Hazard Assessments (HAZOP, What-If, LOPA) while ensuring compliance with DSEAR, ATEX, COMAH requirements; support site MoC processes.
• Develop PFDs, P&IDs, mass/energy balances, safe operating envelopes; own process design basis ensuring accurate technical documentation is maintained within EQMS.
• Author SOPs and SSOW required for safe start-up; provide day-to-day process engineering support during start-up including troubleshooting issues and driving corrective actions to closure.

CAPEX:

• Lead and support capital expenditure projects from concept through commissioning, ensuring all deliverables meet design intent, are completed on time, and stay within budget.
• Own technical project definition including FEED, equipment sizing, specification development, RFQs, and participation in design reviews.
• Manage technical interactions with suppliers, contractors, and equipment vendors by building trusted business-partner relationships that facilitate successful project outcomes.
• Plan and execute commissioning, qualification, and validation activities such as pre-start checks, functional testing, water trials, and production trials to ensure seamless handover for beneficial use.
• Escalate project risks, budget deviations, or programme slippage promptly through established governance processes to maintain transparency and accountability.
• Provide day-to-day technical process engineering support to manufacturing operations by troubleshooting process issues and driving corrective actions through to closure.
• Develop and maintain PFDs, P&IDs, mass and energy balances, as well as safe operating envelopes for optimal plant performance.
• Support root cause investigations using data-driven analysis of process performance to ensure effective action close-out and continuous improvement.
• Participate in process hazard assessments (HAZOP, What-If, LOPA) as a subject-matter expert while driving resulting actions to completion for enhanced safety compliance.
• Collaborate closely with Operations, Engineering, Quality Assurance, EHS, R&D, Supply Chain, Commercial teams, and external partners to achieve site objectives.

The ideal Engineers will bring substantial experience from an industrial manufacturing setting, such as chemical, oil & gas, Petrochem or a similar process engineering industry, with demonstrable experience on their application delivering previous relevant projects:

• Degree in Chemical or Process Engineering or equivalent experience demonstrating comprehensive knowledge of chemical engineering principles.
• Minimum of five years' proven experience in process engineering within an industrial manufacturing environment where you have delivered relevant commissioning or CAPEX projects.
• Demonstrable understanding of process safety standards including DSEAR/ATEX legislation.
• Strong analytical capability paired with a data-driven mindset that enables effective troubleshooting and root cause analysis for process optimisation.
• Excellent communication skills, both written and oral, that allow you to convey complex technical information clearly across multidisciplinary teams.
• High competency with MS Office suite for technical documentation management and reporting purposes.
• Ability to take ownership of tasks by delivering activities through to completion while maintaining accuracy in controlled technical documentation.
• Proactive approach focused on continuous improvement initiatives that drive operational excellence within the manufacturing environment.
• Awareness of GMP manufacturing practices as well as ISO management systems is advantageous.

This organisation stands out as a global leader in their field, and both roles have the potential to extend or even become permanent positions in the future. These contract requirements are fairly urgent and the business are able to onboard the successful applicants at short notice - if you are interested in either of these roles please get in touch or apply using the link provided.
