Job Description

8fit understands the obstacles people face on their fitness journey. It often isn’t easy, and there’s no one-size-fits-all way to find lifelong health. That’s why we’ve set out to build the best way for people to achieve their personal fitness goals. 8fit makes healthy living fun and simple by providing tailored workouts, meal plans and guidance in one easy-to-use app.

Engineering at 8fit

We’re organized into cross-functional delivery teams with clear goals and lots of autonomy. We’re constantly looking to improve our tooling and working process.

We believe working culture is not a list of platitudes. It's defined by the behaviours of the team.

That being said, here are a few of the ideas we feel strongly about:

Great communication — The ability to exchange ideas efficiently is an important part of your skillset.

Take ownership — Operate with autonomy, mastery, and purpose. Do your own research, talk with others on the team and don’t let anything stand between you and the results you want.

Venture outside your comfort zone — Ask questions. Be critical. Suggest ways of improving internal process. Be humble, admit mistakes readily, and never stop learning.

Bias towards action — Assume your first iteration will need improvement. The sooner you launch the sooner you can improve. Instead of speculating come back next week with real data.


- Scaling rails applications, code organisation patterns, architecture

- Heroku, AWS, Docker

- PostgreSQL


In this role you'll be responsible for the main backend application that powers the API used by the mobile clients, as well as the internal administration pages used for content creation.

You'll work with the product managers to plan and implement new features. You should be very good at capturing business concepts and processes in code. You'll be responsible for uptime and performance.

This role requires a balance of technical chops, and strong communication and organisation skills. You'd have a small team of rails / devops engineers reporting to you.

We're using Rails for the main application, so experience with Rails at some degree of scale would be required.

This role is ideal for someone with lots of experience working as a Senior Engineer, who's looking to improve their soft skills and gain some leadership experience.

It’s quiet, bright, well-stocked with healthy snacks, and every Friday, we get together for a healthy lunch.

Other perks of being an 8fitter:

  • Flexible office hours, to ensure you have plenty of time to enjoy life (and fit in a workout)
