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.

About the role:

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.

The core squad helps deliver the underlying systems and APIs that power our business, from registration flows to ingesting results from labs. You will take ownership of projects and work closely with other internal teams as well as designing and building public APIs. With a can-do attitude and a strong product mentality, you are happy to get stuck in designing, building and maintaining scalable, reliable and performant systems.


  • Build functionality that delivers value
  • Automate tasks
  • Build beautiful user interfaces
You will be set up for success if you have:
  • Strong experience in Node.JS and React JS
  • Strong knowledge of databases (SQL, GraphQL, NoSql etc.)
  • Experience working with and designing APIs
  • Agile development product mindset. Ability to create rapid prototypes and understand how these differ from production level code
  • Test automation
  • Ability to work in a changing environment
Ideal behaviours:
  • You're not married to one technology and choose the right tool for the job
  • You like to move fast and make an impact
  • And most of all you're enthusiastic and get shit done
What would make you amazing:
  • Experience in another language (Typescript, PHP or Python)
  • Any mobile experience (react native)
  • Experience with AWS services (S3, Aurora, ECS, SQS, API Gateway etc.)
  • Messaging systems like RabbitMq, AWS SQS or Kafka
  • Microservices experience
Our Tech Stack:
  • We believe in the right tool for the job but we are moving towards a full Typescript stack deployed via CI/CD to AWS
  • React JS/Native on the front end
  • Node on the backend (moving away from PHP monolithic to more event driven microservice architecture) with some Python sprinkled on for the more data science parts
  • On the database side MySql/Postgres and GraphQL
