Chief Technical Officer

Location: United Kingdom – frequent travel expected to St. Helens / Liverpool if not locally based.

Our client is a fast-growing Battery Energy Storage System (BESS) platform backed by a leading infrastructure investment fund. With an ambitious pipeline of utility-scale energy storage projects across the UK, the platform is entering a key phase of technical scale‑up, delivery optimisation, and organisational growth and is seeking a Chief Technical Officer (CTO) to lead its technical, engineering, procurement, and construction strategy.

What will you be doing?

• Define and own the overall technical and delivery framework for BESS projects across the portfolio, ensuring projects are delivered safely, on time, within budget, and aligned with long-term performance and reliability objectives.
• Establish and oversee delivery models across EPC, multi-contracting, and hybrid structures, implementing clear governance frameworks, stage gates, escalation mechanisms, and decision‑making processes from Ready-to-Build (RtB) through to COD and operational handover.
• Act as the final technical authority across BESS and Balance of Plant (BoP) matters, including system architecture and design philosophies, technology selection and standardisation, and major engineering risks.
• Define and maintain group‑wide technical standards, ensuring projects are optimised for safety, constructability, operational reliability, performance, and lifecycle cost efficiency.
• Lead procurement strategy and supplier oversight across BESS systems, BoP, and EPC scopes, supporting major commercial negotiations and validating technical positioning around warranties, guarantees, interfaces, and supplier risk exposure.
• Oversee portfolio‑level project delivery performance, reviewing readiness, schedules, cost‑risk profiles, mitigation plans, and execution quality across multiple concurrent projects.
• Define principles and standards for civil and structural works, ensuring scalability, constructability, and cost efficiency are embedded early within project designs.
• Build and structure the technical and delivery organisation as the platform scales, developing engineering leadership capability and clear interfaces between internal teams, EPCs, OEMs, contractors, and advisors.
• Work closely with the CEO, CFO, investors, and executive leadership team to support strategic growth initiatives, project financing discussions, and long‑term platform expansion.

Are you the ideal candidate?

• Degree in Engineering, Electrical Engineering, Power Systems, Energy Infrastructure, or a related discipline.
• 15+ years of experience across energy, infrastructure, or capital‑intensive project environments with a strong engineering and project delivery background.
• Previous experience in senior technical leadership roles such as CTO, Head of Engineering, Head of Delivery, or equivalent.
• Strong experience leading utility‑scale BESS projects from development through construction and commissioning.
• Deep technical expertise across BESS technologies, Balance of Plant (BoP), grid integration, and large‑scale infrastructure execution.
• Experience building technical standards, governance frameworks, scalable delivery organisations, and engineering best practices.
• Strong understanding of supplier management, procurement strategy, technical risk allocation, warranties, and commercial interfaces.
• Comfortable operating within entrepreneurial, fast‑growing, or private equity‑backed environments where processes and teams are being built and scaled.
• Strong strategic mindset combined with a pragmatic and hands‑on approach when required.
• Commercially aware with sufficient financial acumen to engage in project financing and investment discussions.
• Project management certifications such as PMP, APM, IOSH, APMG, or equivalent would be advantageous.

• Performance‑based annual bonus
• Long‑term incentive potential
• Opportunity to join a high‑growth platform backed by a leading infrastructure investor
• Strategic leadership exposure with direct influence on the platform’s expansion
• Opportunity to shape the technical foundations and long‑term scalability of a rapidly growing BESS business
• Opportunity to play a key role in accelerating the energy transition
