Lead Data Center Design Engineer for AI Infra

Radiant; Greater London; On-site; GBP 90,000 - 130,000; Full time

Job summary

Radiant is redefining AI infrastructure design. The role leads the creation of electrical, mechanical, civil and BIM design standards for live data center projects, with hands-on engineering in early stages.

You will review packages, set high-density GPU cooling and power topology standards, and collaborate with EPCs and consultants in workshops. You’ll build out senior technical resources across projects as the portfolio grows, while maintaining a practical, no-blueprint approach to problem

Qualifications

• Attitude matters more to us here than number of years of experience.
• Strong hands-on design experience in electrical or mechanical engineering for data centres or similar mission-critical facilities.
• Comfort producing or heavily marking up design output yourself, not just directing others.
• Working knowledge of high-density GPU cooling (air and liquid) and power distribution/redundancy topologies.
• Ability to set a standard from a blank page - you won't be handed one.
• Confidence pushing back on consultants and EPCs directly on technical substance.
• We care much more about how you think through a design problem than the number of years on your CV.
• Engineering degree (mechanical, electrical, or related discipline).

Responsibilities

• Write and maintain electrical, mechanical, civil and BIM design standards yourself — there isn’t an existing standard to inherit.
• Personally review and mark up design packages from consultants and contractors, not just sign them off.
• Get into the detail on switchgear, cooling strategy (air and liquid) and structural design for GPU-density loads.
• Sit in design workshops and RFI resolution directly with EPCs and consultants — you’re expected to be in the room, not one step removed.
• Write technical requirements and personally review technical responses from suppliers and contractors.
• Build out electrical, mechanical, civil and BIM leads as the portfolio grows — but expect to be the most senior technical resource on more than one project at a time in year one.
