• You will 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.
• You will 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.
• You will define and maintain group‑wide technical standards, ensuring projects are optimised for safety, constructability, operational reliability, performance, and lifecycle cost efficiency.
• You will 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.
• You will oversee portfolio‑level project delivery performance, reviewing readiness, schedules, cost‑risk profiles, mitigation plans, and execution quality across multiple concurrent projects.
• You will define principles and standards for civil and structural works, ensuring scalability, constructability, and cost efficiency are embedded early within project designs.
• You will 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.
• You will work closely with the CEO, CFO, investors, and executive leadership team to support strategic growth initiatives, project financing discussions, and long‑term platform expansion.

• Degree in Engineering, Electrical Engineering, Power Systems, Energy Infrastructure, or a related discipline.

  • or equivalent.
• Strong experience leading utility‑scale BESS projects from development through construction and commissioning.
• Deep technical expertise across:
  • BESS technologies,

  • 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.
