APIs You Won't Hate


Kandidate · Back-end Developer

🔙🔚 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. You will take ownership of projects and work closely with other internal teams as well as 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 by introducing simplicity, not complexity whilst solving real world problems.

🧬 Who we are:

Chronomics is a tech-bio company that builds bio-infrastructure to power the use of biomarkers in everyday life, improving outcomes across industries and society. We are on a mission to “make the unseen actionable”. And we are hiring - come and join the team!

We are at the dawn of a ‘bio revolution’ which will transform societies, economies and our lives over the coming century. Advances in biomarkers - quantifiable information about each of us derived from analysis of molecules - offer the possibility to change what it means to ‘personalize’ everyday products and services and, perhaps most importantly, our ability to measure their effectiveness.

At Chronomics, we are building the technology engine to power this revolution. Founded by scientists from the world’s leading research universities, we have brought together an expert team across science, technology, business and operations to create an end-to-end bio-infrastructure platform to radically simplify, speed-up and scale how organizations integrate biomarkers into their offerings.

By enabling access to biology at a software level for the very first time, our dynamic platform has reduced the cost, time and complexity of utilizing bio-science by several orders of magnitude. Chronomics has quickly become a trusted partner of some of the world’s leading organizations, spanning industries as diverse as health, wellness, nutrition, retail, travel, beauty, fertility and pet. Together with our clients, we are powering diagnostics for tele-health; creating scientific diet plans; transforming how people sleep, customizing skincare routines, tracking the biological impact of fitness programs and facilitating safe travel and work in the midst of COVID-19.

By integrating bio-science into their consumer and employee journeys, our clients are transforming their customer value propositions, improving real-life outcomes and building a significant and sustainable competitive advantage.

✔️ As one of our Software Engineers we will love you because:

  • You're not married to one technology and choose the right tool for the job.
  • You have a product mindset and understand creating value, not features.
  • And most of all you're enthusiastic and get the job done.

🔥 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.


🚀 What we need from you:

  • Strong experience in Node.JS and JavaScript
  • Strong knowledge of databases (SQL, GraphQL, NoSql etc).
  • Design, build and maintain scalable, reliable and performant systems.
  • Write secure, scalable, documented code with automated tests.
  • Experience working with and designing APIs.
  • Experience scaling products.
  • Agile development product mindset.
  • Ability to create rapid prototypes and understand how these differ from production level code.
  • Test automation.
  • Some DevOps knowledge.

☄️ Nice to have:

  • Typescript.
  • Experience in another language (PHP or Python).
  • Messaging systems like RabbitMq, AWS SQS or Kafka.
  • Experience with AWS services (ECS, Fargate etc).
  • Experience working on high scalability websites.
  • Microservices experience.


What you can expect from us:

💵 competitive salary

⏳ flexible hours and remote working

🏖 25 days of holiday (not including bank holidays)

I&D statement
Be your authentic self at work

As we go global, we want our team to reflect the diverse and multicultural world we live in.
So, we choose to talk about Inclusion and Diversity [in that specific order] because we believe Diversity won’t be successful without Inclusion first. We build teams, cultivate leaders and create a company that’s the right fit for every person in it.
We look forward to hearing from you!

Please note, we don't accept applications from recruitment agencies - thank you!
