People Team

Our People team sits at the heart of Marshmallow, partnering with leaders across the business to build high-performing, inclusive, and engaged teams. We focus on creating a consistent, high-quality People experience at every stage of the employee lifecycle, enabling our people to do their best work while staying true to our values.

As a Senior People Partner, you'll work as a trusted strategic partner to senior leaders and leadership teams across Marshmallow, shaping the people agenda for your leadership groups and driving meaningful impact on business performance.

You'll bring a confident, independent approach to complex employee relations, organisational change, and people strategy, operating with a high degree of autonomy and sound commercial judgement. Where you engage with other members of the People team, it will be to collaborate and share expertise, not for day-to-day guidance.

This role goes beyond execution. You'll proactively identify people risks and opportunities within your client groups, influence leaders to make better people decisions, and contribute to the broader development of our people practices at Marshmallow. You'll bring data and insight to the table, helping leaders connect their people strategy to business outcomes.

You'll be someone who thrives in a fast-moving, scaling environment — comfortable with ambiguity, skilled at building trust quickly with senior stakeholders, and able to balance the strategic with the hands-on when the moment calls for it.

What you'll be doing

• Partner with technology and other leaders across the business to navigate people challenges with confidence, from day-to-day guidance through complex employee relations matters
• Provide strategic guidance on organisational design, workforce planning, and team effectiveness across the organisation
• Support the full employee lifecycle from onboarding, performance management, development and exits – enabling people to thrive
• Lead on frontline employee relations support for multiple UK business areas, ensuring fair, consistent, and legally compliant outcomes
