We're putting together a talented team to build the #1 training platform for Runners

We help everyday runners become outstanding by building an incredible app providing world-class training, coaching and community for everyone, whether you're improving your 5k time or training for your first marathon.

We’re growing extremely fast! In November 2023 we closed a $6.5M funding round led by JamJar with participation from Eka Ventures, Venrex and Creator Ventures. In 2024, we were selected by Apple as one of three global finalists for the 2024 iPhone App of the Year, reflecting the innovation and impact of what we’ve built & in 2025 we were acquired by Strava! 🤯 🎉

Our ambition is huge: to become the go-to global leading training platform for millions of runners everywhere. We’re growing with purpose and looking for people who want to build something meaningful with lasting impact. With the recent acquisition by Strava accelerating our journey, now is a really magical time to join 🚀

The team you’ll join

We’re looking for a Staff Full Stack Engineer to play a pivotal role in driving the technical success of the Runna app. This is a hands-on role, within our App Team, where you’ll work across multiple squads, 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). We have a jam packed roadmap, with countless opportunities to champion new technologies, work on meaningful problems that impact millions of runners, and improve existing architecture to elevate the whole of our engineering team.

What you’ll be doing

You’ll be a multiplier for the engineering team—mentoring developers, improving processes, and guiding the evolution of our systems as we scale. We’re looking for someone who is not only technically excellent, but also a creative problem solver and collaborative leader who brings energy and clarity to fast-paced environments.ca

• 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).
• Coach and support engineers by providing technical guidance, mentorship, and code reviews without creating bottlenecks.
• Collaborate with Product, Design, and Engineering Leads to define the best solutions for user experience, balancing speed, quality, and long-term technical goals.
• 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.
• Maintain and grow a high-performing engineering culture based on ownership, knowledge-sharing, and continuous improvement.

What you’ll bring to the team:

• 5+ years of professional experience in software engineering, with a focus on technical leadership and driving projects end-to-end.
• Deep expertise in TypeScript/JavaScript, with a strong foundation across the full stack.
• Proven track record of leading the architecture and successful delivery of large-scale React-Native mobile applications in a production environment.
