Senior People Operations Manager

About the Role

We're looking for a People Operations Specialist to provide day-to-day People Ops support for our US team — currently our second-largest hub and growing quickly. Reporting to our London-based Head of People Ops & Data, you'll be the main point of contact for everything from onboarding and offboarding to benefits and compliance for our North America colleagues. You'll work alongside a colleague from our People Partnership team who previously held this role, so you won't be starting from scratch.

This is a hands-on, high-autonomy role. You'll run US People Ops day-to-day, plug into broader People Ops projects as our team scales, and have support from the wider global People team whenever you need it — we operate as one team, not in regional silos. We're a fast-growing company, not yet a large, fully specialised corporate People function — which means this role, and the way it's scoped, will evolve as our needs change. You should be genuinely comfortable with ambiguity, happy to build process as you go rather than inherit a finished playbook, and energised by the idea of taking on new areas of ownership as the company grows. If something isn't working as well as it could — a process, a system, a workflow — we want someone who takes the time to understand what's already there and why, then brings solutions rather than just flagging the problem.

Performance Cycles & Projects

• Support our bi-annual performance review cycles
• Get involved in broader People Ops projects as we continue to scale

A couple of things are must-haves given the seniority of this role

• Solid, hands-on experience with an HRIS platform (we use HiBob)
• Several years of experience in People Operations or HR, ideally with exposure to US employment law

Beyond that, a few things would be especially useful to bring with you:

• Experience with US benefits administration, particularly healthcare plans and 401(k)s
• Experience with US visa and immigration processes is useful
• Good organisation and communication skills, and confidence working autonomously across time zones
• Comfortable handling sensitive and confidential information with discretion
• Genuine comfort with ambiguity — this role, like our company, is evolving, and we're looking for someone who's energised by that
• Solution-oriented when gaps are identified — you take the time to understand what's already in place and why, then bring practical ideas for how to improve it, rather than just raising the problem

If you're not sure you tick every box in that second list, we'd still love to hear from you.

Benefits

• Own the US benefits programme end to end — enrolment, renewals, open enrolment, and broker relationships
• Be the go-to person for benefits questions, and help keep our offering best-in-class as we grow

What we offer
