Role: Sales Engineering Manager (Mechanical Bias)

Location: Central London

Employment Type: Full-time, permanent, on-site

Salary: £95,000 - £100,000

We’re working with a specialist contractor operating within critical environments, delivering full-scope design, build and infrastructure solutions across complex projects.

They’re now looking to bring in a Sales Engineering Manager to lead the front-end engineering function - someone who can take ownership of technical solutioning, pre-construction, and commercial input across bids and client engagements.

This role leans heavily toward mechanical systems, so a strong background in cooling and associated infrastructure is key. That said, you’ll still need to understand how everything ties together across the wider M&E and data centre ecosystem.

What you’ll be doing:

Leading the technical and engineering input across bids, tenders, and early-stage opportunities
Translating client requirements into robust, deliverable technical solutions
Owning the pre-construction phase - including design input, estimation, and bid strategy
Producing and reviewing proposals, technical submissions, and supporting documentation
Carrying out take-offs, BOQs, and labour build-ups to support accurate pricing
Driving value engineering and alternative solutions to improve both cost and deliverability
Acting as the technical lead in client meetings, design reviews, and bid presentations
Managing supplier and subcontractor engagement during tender stages
Supporting handover into delivery teams, ensuring scope and design intent are clear

Technical focus:

This role is mechanically led, with a strong emphasis on:

Cooling systems (CRAC/CRAH, chilled water, DX, free cooling)
HVAC and thermal management within critical environments
Integration with electrical systems (LV distribution, UPS, generators)
Coordination with wider infrastructure including containment, cabling, and white space fit-out

What they’re looking for:

Strong background in mechanical engineering, ideally within critical or complex environments
Proven experience across design, estimation, and pre-construction
Experience in a sales engineering, bid, or solutions role
Ability to take ownership of technical proposals from concept through to submission
Solid commercial awareness - understanding pricing, risk, and margins
Experience engaging with clients, consultants, and internal delivery teams
Comfortable reviewing drawings and producing technical documentation

Ideal background:

Mechanical bias within M&E contracting or building services
Experience working on large-scale commercial, industrial, or mission-critical projects
Data centre experience is beneficial, but not essential
Candidates from sectors such as pharma, industrial, manufacturing, or other complex environments will also be considered
