Coordinador Senior de Personas

This role is based in London, Bristol or Edinburgh and requires an existing right to work in the UK.

At this time, we are not able to offer visa sponsorship for this role. We are committed to building a diverse, global team and our sponsorship policy is evaluated on a role-by-role basis. We encourage you to keep an eye on our careers site to stay informed about future opportunities where we are able to offer visa sponsorship.

What will I be doing?

• Own the People service desk queue day-to-day: triaging, responding to, and resolving employee queries, and keeping response times and queue health on track.
• Continuously improve our Jira Service Desk itself - refining triage, workflows, and automations - and feed recurring ticket themes back into our People Bot's knowledge base, so the answers people get before they ever need a human just keep getting better.
• Be the main point of contact for new joiners between offer and day one, partnering with Talent Acquisition to make pre-boarding seamless and ensuring nothing falls through the cracks.
• Own and continuously improve the onboarding experience end-to-end - from offer acceptance to day one and beyond - so every new hire feels genuinely welcomed and set up for success.
• Support payroll inputs, benefits administration, and compliance activities, making sure our processes hold up against internal policy and employment law requirements.
• As you grow into the role: help audit and redesign People processes, identifying where automation, AI, or self-service can reduce manual effort and put information directly in employees' hands.
• Roll up your sleeves on cross-functional People projects as they come up - whether that's a Reward cycle, a hiring initiative, or an experience improvement.

About You

Ideally, you'll have/be:

• Some experience in a People Operations or HR administrative role, with a genuine interest in how operational rigour underpins the employee lifecycle.
• Hands-on comfort with a HRIS, ideally Workday - confident entering and updating records accurately as part of onboarding and lifecycle admin, even if deeper reporting and analysis isn't your focus.
• A naturally curious, detail-oriented approach to data - happy to flag something that looks off, even while you're still building the experience to know exactly why.
• Some exposure to payroll input processes, or strong eagerness to learn them, with the attention to detail accurate processing demands.
• Some experience administering employee benefits (enrolment, changes, queries), and comfortable being a point of contact when something needs sorting.
• A habit of noticing when a process is clunky and saying so - you don't need to have led a full redesign yet, but you think about why something works the way it does.
• Experience using a service desk tool (Jira or similar) to manage and triage a queue, with a good instinct for keeping things moving and knowing what needs escalating.
• Awareness of compliance and employment law basics, and the judgment to flag rather than guess when something feels off.
• Clear, warm communication - equally comfortable writing to a nervous new joiner as flagging something to a manager.

What will set you apart:

• You're curious about what AI and automation can do for People Operations, and you're already poking at tools and forming opinions rather than waiting to be told to explore what's next.
• You hold yourself to a high bar, and you'll say so if you think something could be better - even if you're not yet the one leading the fix.
• You share what you know and keep people in the loop - a new joiner never feels like they're chasing you for answers.
