We are seeking a Business Unit Director to lead and grow a strategically critical nuclear business unit within Expleo's UK operation. This role combines front-end market leadership and business winning with full accountability for operational delivery, financial performance and team leadership.
This is not a pure sales role - and not a delivery-only leadership position. You will own the full lifecycle: shaping market strategy, winning complex work, building trusted client partnerships, and ensuring programmes are delivered safely, profitably and to the highest nuclear standards.
You will operate as a senior leader within the nuclear leadership community, responsible for translating market opportunity into a scalable, high-performing business unit with strong culture, capability depth and repeatable growth.
The Role
As Business Unit Director, you hold end-to-end accountability for a defined nuclear portfolio, including:
* Business growth and market positioning
* Winning and securing major programmes and frameworks
* Operational delivery performance and client outcomes
* Financial results (revenue, margin, cost and risk)
* Leadership, development and engagement of multidisciplinary teams
You will work closely with executive leadership, delivery leaders, engineering authorities and commercial teams to ensure Expleo is positioned as a long-term strategic partner across the UK nuclear landscape.
This is a high-impact leadership role requiring credibility at board, programme and regulatory levels, and the ability to balance commercial ambition with nuclear safety, quality and delivery integrity.
