Role: Senior Sales Engineer – MEP (Mechanical Bias)
Location: London, UK
Role type: On-site / Full time / Permanent
Salary: £75,000 - £90,000
We’re working with a leading data centre specialist delivering full lifecycle solutions across design, build, and managed services.
They’re looking for a Senior Sales Engineer with a strong mechanical bias to sit between the client, commercial team, and delivery function, someone who can take complex requirements and turn them into technically sound, commercially viable solutions.
This is not a pure sales role. It’s a technical solutioning position, heavily focused on mechanical systems within MEP environments, supporting bids, shaping designs, and driving winning strategies.
What you’ll be doing
- Leading the technical solutioning of bids and proposals, with a strong focus on mechanical systems
- Interpreting client requirements and translating them into practical, buildable MEP solutions
- Supporting tenders from early engagement through to final submission
- Working closely with supply chain, design teams, and commercial leads to build accurate, competitive proposals
- Developing cost models, estimates, and technical submissions aligned to project scope
- Identifying risks, value engineering opportunities, and efficiencies within designs
- Acting as the technical authority during the bid phase, particularly across mechanical packages
- Contributing to bid-winning strategies, ensuring clear differentiation against competitors
- Leading technical reviews and supporting internal governance processes
- Managing handover into delivery teams, ensuring full understanding of design intent, scope, and assumptions
- Supporting project teams post-award as a Subject Matter Expert (SME) where required
- Building strong relationships with clients, partners, and internal stakeholders
What you’ll need
- Strong background in MEP environments with a clear mechanical bias
- Experience in data centres, mission-critical, or complex infrastructure projects
- Proven experience in a Sales Engineer, Bid Engineer, Estimator, or Pre-Construction role
- Strong understanding of mechanical systems such as HVAC (CRAC/CRAH, chilled water systems, DX cooling), cooling strategies for data centres (air-cooled, liquid, containment), pipework, pumps, and associated plant systems
- Ability to interpret technical specifications and produce solution-led proposals
- Commercial awareness, including costing, margins, and risk identification
- Experience working with contractors, integrators, or specialist providers
- Strong stakeholder management and communication skills
- Comfortable working across multiple bids and deadlines
Nice to have
- Experience working on hyperscale or colocation data centre projects
- HND or Degree in Mechanical Engineering (or similar/demonstrable experience)
- Exposure to both mechanical and electrical packages (mechanical lead preferred)
- Relevant qualifications in mechanical engineering or building services
- Knowledge of commissioning, IST, or project delivery phases
