Full time FTC (8-14 months)

London (W1) based with regular travel

WHO ARE WE?

The MISSION Group Plc delivers measurable, results-driven campaigns as the preferred creative partner for real business growth. We offer top-tier agencies, strategic specialisms and global reach delivering outstanding performance for brands.

With over 800 people across three continents, our agencies span five key specialisms: Integrated B2B/B2C, Sports & Events, Property, Healthcare, and Public Relations. We are ambitious in delivering our growth agenda. We call it Work That Counts™.

THE PEOPLE TEAM

Our People Team is a collaborative, forward-thinking function operating across the UK, both onsite and remotely. We combine expertise across Strategic HR, Business Partnering, Talent Acquisition, Learning & Development, and People Operations, supported by best-in-class technology.

At our core is a principle of care, alongside a strong focus on continuous improvement and delivering real value to our agencies.

THE ROLE

We are looking for a Senior People Business Partner to join our People Leadership Team on an 8-14 month fixed term contract, reporting into the Group Head of People.

This is a high-impact, primarily London-based role embedded within one of our larger agencies:

Bray Leino, krow or Mongoose.

You will sit at the heart of the Agency leadership, shaping and delivering on people strategies that drive performance, growth and transformation. This is a fantastic opportunity to truly partner with Agency CEOs and senior business leaders across the Agencies, helping them to develop and deliver their people plans.

Leading a small team of one to two People Business Partners, you will bring curiosity and pragmatism along with a commercial, outcomes-focused mindset and real pace to how you operate. This is not traditional HR. You will influence decisions at the top of the Agency, challenge thinking and turn strategy into action.

You will be visible, connected and plugged into the day-to-day of the agency, building strong relationships and a deep understanding of what makes the business tick. Using insight, instinct and experience, you will provide clear, confident guidance that delivers real impact.

RESPONSIBILITIES

• Partner with Agency CEOs and senior leaders to shape business strategy through a people lens

• Develop and deliver commercially aligned people plans that drive growth and performance

• Build strong, trusted relationships with leadership teams

• Lead organisational design, change and integration initiatives

• Use data and insight to inform decision-making and challenge thinking

• Strengthen leadership capability and embed a high-performance culture

• Lead complex employee relations matters with a pragmatic, commercial approach

• Champion culture, engagement and ED&I initiatives

• Collaborate with People Operations to ensure consistent, scalable practices

• Contribute to group-wide transformation and strategic projects

This role is highly visible and relationship-driven, with a strong emphasis on in-person collaboration. You will spend a minimum of three days per week onsite; mainly in our central London office, alongside regular travel to other UK locations, including occasional overnight stays. Flexibility is essential, with travel aligned to business needs.

WHAT ARE WE LOOKING FOR?

You are a highly credible and commercially astute People leader who thrives in a fast-paced, multi-stakeholder environment.

You will bring:

• Significant experience as a Senior HR or People Business Partner in complex or multi-entity organisations

• Strong ability to influence, support and challenge senior stakeholders at Agency CEO or MD level

• Proven track record of embedding within businesses and delivering measurable impact

• A commercial mindset, linking people strategy to business outcomes

• Expertise in organisational design, change management and integration

• Confidence operating at both strategic and hands-on levels

• Strong employee relations knowledge and understanding of UK employment law

• Resilience, adaptability and comfort navigating ambiguity

• Flexibility to travel regularly and work in a highly visible, London-based role

• CIPD qualification or equivalent experience

• Agency experience is a great-to-have, but not essential

AND IN RETURN…

• Holiday Allowance –25 days of annual leave (plus Bank Holidays)

• Future-Proof Pension – Enjoy peace of mind with our company pension scheme, boosted by enhanced employer contributions after your first year.
