Head of Service Management - Senior Manager in Watford

Whatever stage you’re at in your career, with us you’ll have an opportunity to grow and develop. Delivering essential infrastructure services for life, while being safety first, and client and customer centric in a friendly, fun and respectful environment where you are encouraged to thrive.

Our Group Support roles are vital in making sure we can help over 11,000 people deliver essential infrastructure seamlessly across water, energy, transport and telecom. We’re looking for a Head of Service Design & Transition who can bring clarity, structure, and strong leadership to how technology services are introduced and supported across M Group Services. In this role, you’ll help shape how our services are designed, prepared, and delivered, ensuring they are stable, supportable, and aligned with the needs of the business.

You’ll influence decision-making at senior levels, guiding teams through a period of major transformation as we move toward more standardised and mature ways of working. You’ll balance rapid delivery with operational reliability, helping the organisation make smarter choices about how services are introduced and supported. If you’re someone who enjoys creating order, improving processes, and building confidence in how change is delivered, this role offers the opportunity to make a meaningful and lasting impact.

In this role, you’ll take ownership of how services move from concept to reality, guiding every stage so that what we deliver is robust, supportable, and fit for long-term use. You’ll bring teams together early in the lifecycle, helping them shape service designs that are clear, consistent, and fully aligned with operational needs. As services progress through delivery, you will be the anchor point that ensures nothing is left to chance—overseeing readiness activities, coordinating testing and validation, and making sure operational teams receive the knowledge and clarity they need to support the service from day one.

You’ll act as the steward of our standards, strengthening our design and transition practices through thoughtful governance, insight, and continuous improvement. You’ll work closely with partners across architecture, cyber, engineering, the SPMO, and our MSPs to keep service integrity at the centre of every project decision. And through strong, visible leadership, you’ll build a team that operates with confidence, accountability, and pride—one that becomes a trusted advisor across the business and a key enabler of stable, high-quality technology services.

Key Responsibilities:

• Proven experience building or leading a Service Design & Transition function in a similarly complex organisation.
• Strong stakeholder management skills, balancing delivery pace with operational readiness and risk.
• Excellent communication skills, able to explain the impact of change on live services with clarity and confidence.
• Solid project planning and delivery discipline—able to establish structure, milestones, and dependencies across multiple teams.
• Hands-on experience owning service readiness and acceptance processes for major changes or project go-lives.
• Experience establishing and governing a scalable release management framework.
