Job description

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

Enter Second Nature.

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

Our habit-change programme – delivered digitally through mobile and web apps – helps people to transform their lifestyle, lose weight, and ultimately reduce their risk for serious conditions such as type 2 diabetes and heart disease.

About us:

• We've positively changed the lives of over 250,000 people
• We're rated 'Excellent' by over 7k of our members on Trustpilot
• We're growing extremely quickly & are now a profitable business
• We’re one of the few consumer health brands that are commissioned by the NHS and leading health insurer, Vitality Health
• We're a leading B2C provider of GLP-1 medication-assisted weight loss programmes, and 1 of 5 NICE-approved providers to deliver these services within the NHS in the future
• Our team members stay with us for an average of 4.3 years

You can find out more about working with us here and here.

The role:

We're looking for an exceptional Software Engineer to work in one of our cross-functional pods focused on building and enhancing features of our core company product that engage and excite users. The pod will be responsible for one of the core company goals (OKRs), deciding what needs to be done to meet that goal.

You will report into an Engineering Manager within the pod and you’ll work with that manager, the Product Manager, and whoever else is needed to achieve the pod's goals. This is a hands-on role and your heavy focus will be on 'writing code' and learning from those around you to improve your tech skills.

Alongside these goals you and your pod will be responsible for enhancements and monitoring of existing features as we strive for continuous improvement and accountability for our work.

You will predominantly work on our core tech stack, including our React Native app, our NextJS website and our NodeJS backend, but there will be opportunity to learn about other parts of our ecosystem such as how we use Terraform and how we set up our AWS infrastructure.

You'll be part of a team of incredibly talented engineers learning and solving problems together and will rapidly take on responsibility and ownership of the things you build.

• Adaptable: Thrive in a fast-changing startup environment
• Lifelong Learner: Continuously seeking knowledge

And, for your interest, this is our all-JavaScript tech stack:

• TypeScript for static typing
• React Native for iOS and Android apps
• NodeJS + Express API servers
• MongoDB our main database
• NextJS for our web frontend

• Quarterly company meet ups and socials
