Second Nature is hiring a

Senior Software Engineer

London, United Kingdom

Our mission:

Type 2 diabetes has become a global epidemic; in the UK, we spend £9 billion a year alone (that’s 10% of the NHS budget) on treating this. What’s shocking is most of this is preventable – through sustained lifestyle and behaviour change.

Enter Second Nature.

We’re here to help people take control of their health. By bringing together behavioural science, technology, and incredible people, our grand mission is to eradicate the global epidemic of chronic lifestyle diseases once and for all.

Our Stage:

We have just closed our Series A fundraising (Dec 2019). We have a team of 85 people (mostly UK based), which will continue to expand over the coming years.

We’re now looking for bright, impactful and empathetic engineers to join our team and engineer solutions to this epidemic.

The role:

You’ll architect and build features across our whole product. You’ll work closely with our health coaching and growth teams to fully understand our users. You’ll mentor junior engineers as the leader in your pod. You’ll leave your mark on our engineering culture with your technical leadership. You will keep growing yourself.

  • You want to build a product that changes people’s lives
  • You take ownership of product features from inception to release
