Payroll Officer in London

Ready to revolutionize healthcare, making it faster and more accessible than ever before?

Founded in 2013 by Dwayne D’Souza, HeliosX was built on a simple but powerful idea: healthcare should be easier to access, faster to receive, and centred around the individual. From day one, we’ve grown without external funding; scaling profitably through technology, disciplined execution, and deep medical expertise.

The Payroll Officer will play a critical role in delivering accurate, timely & compliant UK payroll for HeliosX employees as the business continues to scale rapidly. This role will own day-to-day payroll operations, supporting statutory compliance, payroll controls, reconciliations & employee query management.

Working closely with the People & Finance teams, the Payroll Officer will ensure high-quality payroll data, strong internal controls & a positive employee experience. As HeliosX expands into new markets, this role will also support the development & streamlining of payroll processes, whilst contributing to the evolution of our global payroll framework, including managing relationships with external payroll providers & helping transition certain payroll activities back in-house (such as pensions administration).

What you’ll be doing:

• Run end-to-end UK payroll accurately & on time, ensuring all pay elements, deductions & statutory payments are processed correctly.
• Maintain compliance with UK payroll legislation (PAYE, NI, auto-enrolment), keeping controls strong & processes audit-ready.
• Validate payroll inputs & complete monthly reconciliations using Excel, resolving discrepancies ahead of sign-off.
• Partner with People team & Finance to manage payroll changes (starters/leavers/changes) and provide reporting & month-end support.
• Act as the first point of contact for payroll queries, handling a high volume of requests with discretion & clarity.
• Coordinate with external payroll providers & support process improvements as we scale & expand into new markets.
• Contribute to the continuous improvement & documentation of payroll processes & controls, supporting scalability as HeliosX expands into new markets.

What you’ll bring to the role:

• 2–4 years’ experience in a payroll or payroll-focused role within a medium or large organisation.
• Hands-on experience processing end-to-end UK payroll.
• Experience supporting monthly payroll reconciliations and data validation.
• Exposure to pension administration and statutory payments.
• Experience working with payroll providers or in-house payroll systems.
• Experience operating in a scaling, deadline-driven environment (tech, services, or similar).
• Strong attention to detail with the ability to process high-volume, accurate payrolls.
