Senior Mechanical Engineer | Data Centres | Global Engineering Firm | UK, EU, Multiple Locations

Our client is a well-established, multi-disciplinary Global Engineering Firm with a strong reputation across the UK and Mainland Europe. With a strong pipeline of complex builds and a massive focus on Data Centres, coupled with a growing international presence, they offer a collaborative and supportive environment where innovation is encouraged and career progression is genuinely prioritised.

Known for their hands-on, people-first culture, they blend the benefits of a family-feel organisation with the scale and impact of a major industry player. As a result of their growth and increase in projects, the firm is looking for skilled Mechanical Engineers to work on cutting-edge UK and EU projects.

You’ll be working closely with the Engineering Manager, overseeing the design, coordination, and successful delivery of HVAC, plant and clean utility systems – right through from design to commissioning. There’ll be cross-functional collaboration with design, construction, and supply chain teams – and plenty of scope for innovation. This role involves occasional travel across the UK, Ireland and wider Europe, depending on project phases, with a base in either London or Ireland.

What You’ll Be Doing:

• Lead and shape the design of HVAC, piping, plant, and clean utility systems — from concept through to peer review — ensuring every detail is engineered for success.
• Take ownership of multiple projects, overseeing technical design reviews, driving quality, and offering expert input that ensures seamless delivery.
• Think beyond the drawing board — assess commissionability early on and troubleshoot technical challenges with speed and precision.
• Procure smartly — manage equipment enquiries, requisitions, and manufacturing oversight right through to delivery, with a sharp eye on audit and traceability.
• Champion safety and risk management — contribute to design risk assessments and support the development of safe working practices and method statements.
• Collaborate cross-functionally with design, construction, and supply chain teams to ensure plant systems are installed correctly and fully operational at handover.
• Keep it compliant — ensure all Health, Safety, Environmental, and Quality standards are met, with thorough documentation to match.
• Own the finish line — work closely with the Project Manager to deliver a full project close-out report, capturing lessons learned and success milestones.

Your toolkit:

• Degree in Mechanical Engineering or similar
• 5+ years’ experience in design & build projects, including Data Centres
• Strong knowledge of HVAC, clean utilities, and process piping
• Experience with modular/prefab/commissioning is a plus
• Familiarity with 3D platforms and mechanical calculations
• Sharp eye for troubleshooting and technical detail
• A commercially aware mindset
• Great communication and leadership skills

What’s in it for you?

• Work with a respected, international MEP firm with opportunities to progress into European project work.
• A Collaborative, down-to-earth team culture with support for your career advancement.
• A proactive focus on employee wellbeing, including mental health support.
