Job Details:

HeliosX is one of the world’s fastest growing HealthTech companies. We’re committed to improving the quality, accessibility, and affordability of healthcare for everyone. In 2013, our Founder Dwayne D’Souza recognised the need for prescription healthcare to catch up with other industries by taking advantage of technological innovations – to enable rapid delivery of medications and improved customer convenience. Since our founding, we’ve been entirely bootstrapped – we achieved product-market fit and profitability without ANY external funding whatsoever.

Our mission is to help people across the world get the medications they need, faster. Through our sites and platforms, customers can conveniently access prescription medications and treatments to treat a range of health problems, as well as purchase clinical-grade, personalised skincare. We have dedicated in-house clinical teams authorised to prescribe medications, and we own a pharma business capable of manufacturing many of the medicines and skincare products we provide. We’re an in-house, Direct-To-Consumer (D2C) proposition all the way down – and we’re passionate about that approach.

Our revenue reached a record $76 million USD last year, with unprecedented 32% year-on-year growth. With a 40% year-on-year growth target for 2024, it’s an exciting time to be part of the HeliosX journey. Come and help in making access to medication quicker and easier than ever before in human history!
