Senior Data Analyst

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

How we started:

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. 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. Joining HeliosX now means building systems, teams, and products that will define the next decade of digital healthcare, and doing work that genuinely improves lives, at global scale.

There’s never been a more exciting time to join HeliosX. Come be a part of making our dream of easier and faster healthcare a reality!
