Job Description

Want to make a difference in this world and work on something meaningful? At Chronomics we enable people to quantify how their environment and lifestyle is affecting their health to live healthier and happier lives… all from their DNA. Right now we are also focusing our efforts on COVID-19 and have developed an innovative saliva based test and online platform.

Chronomics is an ambitious health tech start-up that believes people should be in charge of their own health. Health management should be proactive, not reactive and it should be personalised. We are using longitudinal biological data to bring about this revolution. A revolution where not only will people be in control of their own future but also in control of how they contribute to the future of humanity through the use of their data.

This product is just the first step towards a platform technology that will serve as the interface between the biological and digital world. It's an incredibly exciting time to come on board where you can really make a difference.

Engineering is at the heart of what we do at Chronomics and our API first approach drives everything. We are using technology to disrupt science and empower people with their health data.
