Job Description
Head of EPC
Reports to: CEO | Location: United Kingdom (Hybrid) | Type: Full-time, Permanent
About the Company
Tyler Hill Consulting (now part of Zenexa Group) is a renewable energy developer who specialise end to end development of onshore renewable energy assets across the UK, from origination all the way through to RTB.
Tyler Hill Consulting recently received platform-level funding to develop, build and operate our
5GW pipeline of onshore renewable energy assets. Zenexa Renewables Limited has been set up to own these projects long-term to become a leading IPP platform to support the UK's transition towards net zero.
About the Role
Tyler Hill Consulting is seeking a driven and experienced Head of EPC to take ownership of the full Engineering, Procurement, and Construction process across our renewable energy project portfolio. This is a senior leadership role with dual responsibility for both grid connection EPC and power plant (balance of plant) EPC, spanning solar, wind, and battery energy storage projects across the UK and international markets.
The successful candidate will be responsible for delivering projects from design through to energisation, ensuring all phases of construction – including civil, electrical, and mechanical
works are executed safely, on time, within budget, and to the highest quality standards. You will build and lead a high-performing team of project managers, engineers, and construction professionals, and act as the primary interface between engineering, procurement, commercial, and client-facing functions.
We are looking for a candidate with deep expertise across both the grid connection process
(ICP/IDNO, DNO/TO interface) and plant-side EPC delivery, with a proven track record on utility-scale renewable energy projects. Strong commercial acumen, excellent stakeholder management, and the ability to operate across complex, multi-disciplinary environments are essential. The successful candidate will act as a bridge between engineering, project management, and client stakeholders, guaranteeing that design and technical objectives align with project requirements.
