About Thriva

We’re building a personalised healthcare service that can change the way people approach their health.

We want to create a product that millions of people use to understand what’s going on inside their bodies — allowing them to improve their health today and catch any small issues before they become big issues.

We’re always working to make our product as personal as possible. So that people are getting the insights that they really want about their health — whether that’s trying to improve their sleep or live for longer. We’re also building a unique data set that will allow us to learn more than ever about people’s health and predict issues before they even occur.

What it's like to work here

You’ll be working alongside humble people who truly care about what we’re building and how it can help people.

We’re creating something entirely new and we’re aware that we don’t know everything. So we’re constantly trying new things to understand how we can improve peoples' lives. We set quarterly goals which means you’ll always know what you’re doing tomorrow is going to help grow the company over the next few months.

While we do have teams with different specialities and focus, most of our work spans across multiple areas. This means you’ll work with lots of different people on a range of challenging problems.

Startup life can be tough sometimes, so we like to bring as much fun as we can to the office!

What we are looking for

We’re looking for talented engineers who believe in what we’re doing as a company and understand how their skills can help us get there! We want people who are passionate about what they do and love to learn new things.

You should enjoy spending time thinking and reasoning with your team about the best approach to a problem. We’re a small team so while you might be more focussed on one area of the stack, you should relish the challenge of jumping into other areas to help out.
