HeliosX is a group of HealthTech start-ups, with fast-growing operations in the UK and USA. We are dedicated to improving the quality, accessibility, and affordability of healthcare for all, and we’re doing this through a market-disrupting combination of technology, science and excellent clinical care.

Our brands include Dermatica (personalised prescription skincare), MedExpress, ZipHealth and RocketRx.

We are looking for talented and experienced software engineers to work on our range of successful e-commerce sites and help sustain our trajectory of rapid growth. Our front-end stack is based on React and Vue.js, and we are adding Typescript as we go. The rest of our stack is Java-based and runs in AWS.

We operate in an agile way and encourage innovative thinking in everything we do. Every member of our development team has a significant impact on our products. We are constantly looking for ways to improve our systems and architecture to ensure we have a system that is reliable, performant and flexible for future change.

Below is an example of what you’ll be doing in your role:

  • Design, implement and test new features, experiments, or flows.
  • Partner with our product and design teams. Help them explore and prototype new product ideas, clarify requirements, and understand the technical options available for achieving our business objectives and delighting our users.
  • Act as a subject matter expert regarding build tools, code, unit tests, and Java frameworks.
  • Maintain and improve the codebase; recognise duplication, apply SOLID principles, and pragmatically address technical debt as the opportunity or need arises.
  • Mentor other engineers in your areas of expertise.
  • Help to continuously improve our processes, practices and architecture.
  • Help build a great engineering culture with your engineering colleagues across the company.


This is what you’ll need to be successful in this role:

  • Excellent knowledge of Java, Spring context and JPA.
  • A good understanding of how to design and architect a back end system.
  • A pragmatic mindset with a bias to action- you know both what good looks like, and that working is better than perfect, and can walk a line between the two.
  • Interpersonal and communication skills that enable you to explain complex topics to people and audiences from different backgrounds.
  • Comfortable with the amount of change, delivery focus, and ambiguity associated with a company that is rapidly scaling and disrupting existing markets.

If you also have some of the below, that would be fantastic:

  • Bachelor’s degree or higher in computer science or a related subject.
  • Capable with Selenium or other end-to-end testing frameworks.
  • Knowledge and understanding of AWS
  • Experience and skill with Terraform.
  • Working knowledge of Javascript, HTML, CSS, Webpack, HTTP and REST.
  • Experience with React or Vue.


  • Generous equity options for every employee
  • 25 days holiday
  • Private health insurance
  • Contributory pension scheme
  • 40% gym discount
  • Deep discounts on all HeliosX group products (Dermatica etc)
  • Training and development budget
  • Fruit and snacks in the office
  • Free Kindle, books and HeadSpace account
  • Monthly social events (recent trips have included Junkyard Golf, Flight Club and London Shuffle)
  • An awesome team of bright and motivated people to work with!
