What the job involves
- This is a hands-on leadership role where you’ll work across four cross-functional product teams, providing architectural direction, ensuring engineering excellence, and enabling the successful delivery of features across our iOS (React-Native), Android (React-Native), and Apple Watch apps, as well as third-party integrations (Garmin, Strava, Coros, Fitbit, Suunto, etc)

- Lead the architectural design and technical strategy across multiple product teams, ensuring scalable, secure, and maintainable solutions
- Drive the end-to-end delivery of key initiatives, working hands-on to build, test, and ship features across the full stack (mobile, backend, integrations)
- Collaborate with Product, Design, and Engineering Leads to define the best solutions for user experience, balancing speed, quality, and long-term technical goals
- Mentor and support engineers across teams, providing technical guidance, code reviews, and promoting engineering best practices
- Champion developer productivity by improving our CI/CD pipeline, tooling, and internal workflows to accelerate delivery and reduce friction
- Own the release process and support a culture of reliable, continuous deployment—while enabling teams to ship confidently and independently
Application process

- Getting to Know You + Live Coding (45-minute video call, first 25 mins will be an introductory chat followed by two live coding exercises from )
- Take home technical task (max 1-2 hours to complete, or if you have something interesting you recently built and would like to showcase then that's perfectly OK)
- 1.5-hour technical interview (the first half of the call will be used to discuss the take-home technical task from the previous stage and the second half will consist some general architecture/tech questions)
- Meet the team (in-person chat with founder(s) and rest of the team)
- Once the process is finished, we promise to let you know our decision as soon as possible

Our take
As a way to keep fit, running has shot up in popularity in recent years, partially due to accessibility, especially during the pandemic. But for those who want to take running to the next level – whether that be a 5K or a marathon – it can be difficult to know where to start in terms of a training plan. Runna supplies an app with personalised training plans for all types of runs, to help people achieve their running and fitness goals.
Runna was founded in 2020 by running enthusiasts for running enthusiasts, in response to the lack of tools – save paying a professional trainer – available to help runners train. Although there is a wealth of day-to-day running apps available, where Runna stands out is in providing training plans for specific races, which can be distinguished by distance and goal time. In addition, it does this whilst maintaining a sense of community, which has proven to be a popular feature amongst other running apps, and still caters to a range of experience levels.
Runna has since consistent subscriber growth since its launch, serving thousands of users globally. The company plans to build and scale into the future, reach more customers, and expand its team.
