Do you have expertise with power trading?

You could be progressing your career in an impactful Lead Quantitative Trader at a fast-growing energy technology company, backed by major investors, that is transforming the way renewable energy is managed across Europe. Operating large scale battery energy storage assets the business helps balance electricity grids while driving the transition to a cleaner, more resilient energy network. With ambitious plans to expand into hydrogen storage and establish an in-house energy trading desk, it's at the forefront of energy innovation.

As the Lead Quantitative Trader you'll have a rare opportunity to help build and lead a new renewable energy trading quant desk, taking ownership of quantitative trading decisions and commercial priorities within an agreed mandate.

Collaborating with the CEO, you'll identify trading opportunities, investigate strategy performance and challenge the assumptions behind forecasts, optimisation models, backtesting and execution to ensure decisions are grounded in robust commercial evidence.

You'll set the research agenda, encouraging new ideas and hypotheses across the team and prioritising development based on potential value, risk and evidence. Partnering with the Quant Development Lead, you'll translate trading priorities into a clear delivery roadmap, evaluating new strategies through shadow testing and controlled live deployment. You'll also work closely with Trading Operations to oversee live trading behaviour, address exceptions and ensure activity remains within agreed limits and obligations.

Alongside shaping the desk's trading strategy, you'll lead and develop the quantitative trading team, establish high standards and help build the commercial case for further internalisation of trading capabilities. With the opportunity to influence the desk's direction, priorities and future structure, this is a significant leadership role at an early stage of an ambitious energy trading operation with the opportunity to progress to Head of Trading.

About you:

• You have experience of owning live quantitative trading strategies or asset optimisation decisions, with responsibility for performance and risk
• You have experience of identifying commercial opportunity, translating it into a quantitative hypothesis, working with research and engineering to deploy it, and have used live results to improve or stop the approach
• You have a practical knowledge of UK short-term power markets and physical asset constraints, you can demonstrate how uncertainty, forecasts, future asset value and execution mechanics affected decisions made
• You can be hands‑on with models, code and data; you can diagnose gaps between a backtest and live performance and distinguish genuine strategy improvement from favorable market conditions or measurement choices
• You have experience of setting direction, influencing technical colleagues and raising expectations through personal contribution and follow-through
• You're comfortable using modern analytical and AI assisted tools with disciplined assessment of their output

What's in it for you:

• Salary to £200k
