Delivery Interface Manager
THE TEAM
Join JSM’s Power division — a high-performing team delivering complex HV infrastructure projects across the UK.
We operate in a fast-paced environment where technical credibility, structured delivery, and commercial awareness are critical to success. This role sits at the centre of our most significant projects, strengthening the interface between estimating, design, procurement, and delivery.
SCOPE OF ROLE
Reporting to the Associate Director- Electrical, this role exists to bring structure, leadership, and technical authority to the critical design-to-delivery transition across high-value HV infrastructure projects (typically £5m+).
You will lead the coordination of the electrical design lifecycle (11kV–132kV minimum), manage DNO/IDNO and client interfaces, accelerate procurement of long-lead equipment, and provide technical leadership to a team of Project Managers.
This is not a pure design role — and not a purely commercial role.
It is a delivery leadership role requiring immediate operational credibility.
HOW YOU’LL SUCCEED
Design & Approval Process Leadership
Lead structured handover from Estimating to Delivery following project award
Oversee the full HV design lifecycle from grid application to IFC (Issued for Construction)
Manage DNO/IDNO approvals and client-side signoffs
Identify and mitigate design risk early to protect programme and cost
Translate technical issues into commercial and programme impact
Commercial & Procurement Enablement
Understand procurement cycles for major OEMs (e.g. switchgear manufacturers)
Recognise and manage 9–12-month lead time risks
Drive early supplier engagement and order placement
Support NEC/JCT commercial strategy at a high level
Think in terms of programme risk and cash flow impact — not just drawings

Programme, Cost & Risk Oversight
Provide senior oversight of design programmes, ensuring alignment with overall project and portfolio milestones.
Identify systemic design risks, constraints, or capacity issues and implement effective mitigation strategies.
Support commercial teams with design-related change management, claims, and variations.
