Role: Sales Engineering Manager (Mechanical Bias)
Location: Central London
Employment Type: Full-time, permanent, on-site
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
