Job description

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

How we started:

Founded in 2013 by Dwayne D’Souza,HeliosXwas 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. What started as a challenger idea has become one of the most significant healthcare platforms operating globally today.

Where we are now:

We’ve earned the trust of millions of people worldwide through our top-selling products and well-known brands: MedExpress, Dermatica, ZipHealth, RocketRX, and Levity. A lot of our success is down to having our own pharmacies, manufacturers and products – spearheaded by leading in-house medical teams, researchers and pharmacists.

In 2025, HeliosX helped treat over 1.7 million patients worldwide. We reached £781m in revenue, delivering +337% year-on-year growth and cementing our position as the clear market leader in the UK. In 2025 our weight‑loss treatments helped our patients lose 8.5 million kilograms of excess weight; contributing to an estimated 1,300 fewer cardiac events. That’s not just growth; that’s measurable, life‑changing impact at scale.

We’re operating across four markets, with successful launches in Germany and Canada, and growing our reach in the US.

Where we’re going:

2026 is a step-change year. Our ambition is to reach £1.6bn in revenue, expand from four to eight global markets and significantly broaden our condition and treatment portfolio. Over the coming years, you’ll help shape HeliosX into a truly world‑leading healthcare partner; one that combines scale, speed, and clinical rigour to redefine how personalised care is delivered.

• 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.

At HeliosX, we want to improve healthcare for everyone, and to do this we need a team of brilliant people who share that ambition.
