- Produce and review coordinated project schedules, ensuring compliance with supply chain and clients’ expectations.
- Deliver persuasive presentations and demonstrations tailored to technical and executive audiences.
- Lead technical handover to delivery teams, ensuring scope clarity, quality standards, programme, and design intent are preserved.
- Support submittals, technical queries (RFI), and change control during early project phases.
- Capture lessons learned to feed back into sales engineering and standardisation.
- Manage and mentor the sales engineers/estimators; set standards, KPIs, and development plans.
- Implement best-practice go/no-go, bid stage gates, and quality reviews.
- Champion safety, compliance, and engineering excellence in all commercial activities.
- Represent the business, upholding our core values and behaviours with all internal and external customers, clients and third parties.s
- Maintain business and client confidentiality, adhering to applicable Data Protection regulations and Information Security Standards in line with company and group policies and procedures.

- Demonstrable pre-sales/sales engineering experience: scoping, solution design, estimates, proposals, and bid defence.
- Strong knowledge of LV electrical systems, UPS, generators, switchgear, earthing, and cooling technologies (DX, chilled water, free cooling), plus containment and cabling integration.
- Familiarity with applicable standards and regulations (e.g., BS7671, CIBSE Guides, CDM).
