Location: Hybrid (London)
Reports to: Director of Operations for the UK and Europe

We are looking for a highly motivated and capable candidate to join our UK and EU operations team. This role is ideal for someone with strong analytical skills who can break down complex operational processes, ensure compliance with energy regulatory frameworks, and drive process optimisation and synergy across operational teams.

You will work closely with the wider operations team to deliver operational improvements, analyse performance data, and support regulatory and commercial reporting across our energy and flexibility portfolios.

Oak Tree Power is a leading London-based climate-tech start-up that works closely with global grid operators to support the ongoing transition towards a fully sustainable electricity system. We partner with commercial and industrial clients to integrate advanced technologies to reduce energy consumption and CO₂ emissions. Our mission is to empower clients to achieve long-term sustainability by fully embracing net-zero opportunities.

Oak Tree Power is seeking a candidate with a strong interest in the energy and renewable sector, particularly in sustainability and net-zero goals. With a minimum of three to five years’ experience in operational support, data analysis, or energy-related roles—including exposure to flexibility markets, DSO tenders, or balancing services—the role will support the execution of Oak Tree Power’s energy strategy through data-driven insights, operational analysis, and cross-functional collaboration.

Strong communication skills are essential, as the role will work closely with internal teams, clients, and external stakeholders to translate complex data and market requirements into clear, actionable outcomes.
