Senior Manager- Affairs

We set out to build the world’s most trusted consulting firm – creating lasting impact for clients and pioneering a positive, people-first way of working. We work with everyone from FTSE 100 names to bright new start-ups, in every sector.

You’ll find us collaborating shoulder-to-shoulder with our clients, from the big picture right down to the detail: helping them define their strategy, deliver complex change, spot the right commercial opportunities, manage risk, or bring their purpose and sustainability goals to life. Our clients love how we get to know what makes their organisations tick – slotting seamlessly into their teams and being proudly geeky about solving their challenges.

We have hubs in Europe, the US, Asia and Australia, and we work all around the world - from a wind farm in Wyoming to a boardroom in Berlin. Find us wherever there's a challenge to be tackled and an impact to be made.

We collaborate across the criminal justice system and champion the work of Arm’s Length Bodies, helping our clients realise diverse ambitions and better serve citizens throughout the UK. Our Home Affairs team works at the heart of UK Government, partnering with Policing, Defence, Justice and Home Office clients to deliver lasting change.

You will typically lead work streams or engagements, combining structured problem-solving with hands‑on delivery. Alongside delivering impact for clients, you will contribute to developing our people, strengthening client relationships, and supporting the growth of our Home Affairs practice.

You will lead the design and delivery of complex transformation and improvement work, typically owning work streams or defined engagements. This may include:

• Leading multi‑disciplinary teams to deliver transformation programmes that improve citizen outcomes, public safety and operational resilience
• Shaping and delivering business cases, funding strategies and investment decisions for major public sector initiatives
• Designing operating models, service blueprints and organisational solutions for new or transforming government functions
• Leading the assessment and implementation of policy, operational and service changes across policing, justice, defence and Home Office environments
• Establishing effective programme governance, performance tracking and risk management to ensure delivery confidence and measurable outcomes
