Mechanical Technical Lead – Hyperscale Data Centres Location adaptable / home-based, subject to confirmation
Salary open to discussion
Lead the technical development and assurance of complex airside and waterside cooling systems for hyperscale data centres.
This is a senior mechanical engineering role for someone who understands process cooling in detail, can challenge consultant designs and improve reliability, efficiency and standardisation across a major data centre programme.
About the role
You will strengthen the day-to-day capacity of the Mechanical Engineering team, reviewing and developing mechanical systems across new-build, live and evolving hyperscale data centre environments.
The role combines detailed technical review, consultant management, value engineering, reliability analysis and continuous improvement of standard designs.
Key responsibilities
Review and develop airside and waterside mechanical systems for hyperscale data centres
Assess evaporative and non-evaporative process cooling solutions
Review campus plans, general arrangements, CFD studies, noise models and climate data
Complete or review hydraulic analysis, pipe sizing and bin-hour evaluations
Provide technical direction to Architect/Engineer design consultants
Peer review drawings, specifications, calculations, models and sequences of operation
Identify value engineering opportunities without compromising resilience
Analyse redundancy, failure modes and single points of failure
Work with RAM specialists to verify reliability, availability and maintainability
Develop conceptual CAD or BIM sketches to communicate technical solutions
Support upgrades and improvements to critical operational infrastructure
Coordinate construction-originated engineering issues and feed lessons back into standard designs




Produce clear technical presentations using Google Slides
Use Excel and Google Sheets for engineering calculations and technical analysis
Record and close engineering issues through internal tracking systems
Requirements
Strong mechanical engineering experience within hyperscale data centres
Detailed design experience with evaporative and non-evaporative cooling systems
Strong understanding of data centre mechanical topology
Experience with hydraulic and stress-modelling tools
Detailed knowledge of both airside and waterside systems
Experience reviewing consultant designs and resolving technical comments
Strong understanding of redundancy, failure modes and single points of failure
Able to communicate complex engineering issues clearly to technical and non-technical stakeholders
Confident working across design, construction, operations and change-management teams
Water quality management
Corrosion or fouling prevention
CFD and acoustic modelling
CAD or BIM for conceptual design work
Experience improving repeatable or standardised data centre designs
Best-Fit Candidates / Useful Matching Context
Likely target titles include Mechanical Technical Lead, Lead Mechanical Engineer, Principal Mechanical Engineer, Mechanical Design Lead, Mechanical SME, Critical Cooling Lead, Data Centre Mechanical Engineer or Mechanical Technical Programme Manager.
Relevant backgrounds may include hyperscale and colocation data centres, semiconductor facilities, pharmaceutical plants, advanced manufacturing or other mission-critical environments with complex cooling and hydronic systems.
Strong candidates are likely to come from global engineering consultancies, data centre developers, major technology companies, specialist MEP contractors or client-side critical infrastructure teams.
