A major global colocation data centre provider is looking for a Senior Mechanical Engineer to join its growing technical and delivery team.

This is a key engineering position supporting the development and delivery of large-scale, mission-critical data centre facilities. The ideal candidate will come from a strong mechanical design engineering background, ideally within data centres, critical infrastructure, industrial facilities, or other complex mechanical environments.

The role will suit an engineer who is comfortable working across the full design lifecycle and wants to move into a major client-side / colocation workplace, taking ownership of mechanical engineering decisions from concept and design through to construction and commissioning.

Key Responsibilities

- Lead and manage mechanical engineering activities across major data centre developments.
- Review, develop and approve mechanical designs for critical cooling and mechanical infrastructure.
- Provide technical leadership across mechanical systems including chilled water systems, cooling towers, chillers, CRAH/CRAC units, pumps, heat exchangers, ventilation and associated infrastructure.
- Review mechanical design documentation, calculations, specifications, drawings and technical submissions.
- Work closely with external engineering consultants, contractors, equipment suppliers and internal project teams.
- Ensure designs meet project requirements, applicable standards, reliability objectives and operational requirements.
- Identify design risks, technical issues and opportunities for optimisation throughout the project lifecycle.
- Provide technical input into concept, detailed design and design development stages.




- Support procurement and technical evaluation of mechanical equipment and systems.
- Attend design reviews, technical workshops and project meetings with internal and external stakeholders.
- Provide engineering support during construction, testing and commissioning.
- Review and resolve technical RFIs, design changes and site issues.
- Ensure mechanical designs support the required data centre availability, resilience and maintainability standards.
- Contribute to standardisation and continuous improvement of mechanical engineering and design practices across the organisation.

Required Experience

- Bachelor's degree in Mechanical Engineering or a related discipline.
- Significant mechanical engineering design experience, ideally within data centres or other mission-critical infrastructure.
- Strong understanding of mechanical building services, HVAC and critical cooling systems.
- Experience producing, reviewing or managing mechanical engineering designs and documentation.
- Experience working with engineering consultants and multidisciplinary project teams.
- Strong knowledge of relevant mechanical, HVAC and building services standards, codes and industry practices.
- Experience working across complex capital projects from design through to construction and commissioning.




- Strong technical problem-solving and stakeholder management skills.
- Ability to take ownership of technical decisions and operate confidently in a client-side workplace.
- Data centre experience, particularly with hyperscale or colocation facilities.
- Experience with critical cooling and HVAC systems.
- Experience with chilled water systems, chillers, cooling towers, CRAH/CRAC units, pumps and heat rejection systems.
- Experience with computational fluid dynamics (CFD), thermal modelling or data centre cooling analysis.
- Exposure to mechanical design software and engineering calculation packages.
- Experience managing or reviewing the work of external design consultants.
- Chartered Professional Engineer (CPEng) or equivalent professional accreditation.
- Experience with large-scale developments involving significant mechanical capacity.

What I'm Looking For

The strongest candidates will be design-led mechanical engineers rather than purely project or construction-focused engineers.

You should have a strong technical foundation and be comfortable challenging designs, reviewing consultant deliverables and making engineering decisions. Experience working for a mechanical engineering consultancy, EPC, contractor or similar design environment would be highly relevant, particularly where you have progressed into a senior or lead engineering position.

This is an opportunity to move into a major colocation data centre provider and take ownership of mechanical engineering across some of the region's largest and most technically demanding data centre developments.
