Job summary

First Point Group is seeking a senior mechanical design engineer to lead the technical design for high-density data centres and AIcompute facilities in the UK. You will own the design and the numbers, not just the slides, and work directly with customers to define rack densities, cooling strategies, and secure building measures.

You will produce CAD layouts and M&E schematics, develop detailed costings in Excel, and defend complete solutions to senior stakeholders.

Qualifications

• Senior mechanical/building services design experience in data centres or critical infrastructure.
• Recent, practical experience with high-density and liquid cooling.
• Proven CAD drawing and Excel estimating skills.
• Confidence in front of customers.
• Secure building/NPSA experience, or the ability to pick it up quickly.

Responsibilities

• Lead technical discovery with customers: rack densities, liquid/air heat split, resilience, footprint, security and growth.
• Design cooling for AI workloads: direct liquid cooling, CDUs, rear-door heat exchangers, chilled/warm water systems, with calcs on flow and pipe sizing.
• Produce CAD layouts, sections and schematics, integrate M&E into prefabricated modules from factory to site.
• Build detailed Excel pricing, challenge supplier quotes and separate base scope from options.
• Present and defend complete solutions to engineers, customers and senior decision-makers.

Job description

AI is reshaping what a data centre needs to be, and the heat has to go somewhere. My client, a UK designer and manufacturer of prefabricated data centres and secure buildings, is hiring a senior engineer to lead the technical side of their bids for high-density and AI compute facilities, including work for a Tier 1 technology company.

This is a hands-on role. You’ll own the design and the number, not just the slide.

What you’ll do

• Lead technical discovery with customers: rack densities, liquid/air heat split, resilience, footprint, security and growth
• Personally design cooling for AI workloads: direct liquid cooling, CDUs, rear-door heat exchangers, chilled/warm water systems, with your own calcs on flow, pipe sizing and pump duties
• Produce CAD layouts, sections and schematics, and integrate M&E into prefabricated modules from factory to site
• Build detailed Excel pricing, challenge supplier quotes and separate base scope from options
• Present and defend complete solutions to engineers, end customers and senior decision-makers
• Coordinate secure-building measures and NPSA requirements with security specialists

What you’ll bring

• Senior mechanical/building services design experience in data centres or critical infrastructure
• Recent, practical experience with high-density and liquid cooling
• Proven personal CAD drawing and Excel estimating skills
• Confidence in front of customers
• Secure building/NPSA experience, or the ability to pick it up quickly

Nice to have: modular/prefab experience, defence or secure projects, existing UK clearance, CEng, Revit/BIM.

Candidates must be willing to undergo UK security vetting.

A rare chance to sit right where AI demand meets buildable engineering, with real influence on design and commercials.
