Data Scientist (Marketing)

We help everyday runners become outstanding by providing world-class training, coaching, and community for everyone, whether you're improving your 5k time or training for your first marathon. To date we have built iOS, Android, and Apple watch apps that help people achieve their goals by coaching them through the full journey and syncing to their favourite fitness devices.

We’re growing extremely fast and in November 2023 closed a new $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. We want to grow as fast as we can into the future and are looking for individuals who will help us get there. For more about our background and growth check out our Careers Page!

We’re now looking ahead to the future and the people who want to help us build and scale Runna. Our aim is to reach millions of subscribers in the next 5 years and be the go-to training platform for any runner. Now is a magical time to join, we're still small, and everyone makes a foundational difference.

Who we’re looking for

We are looking for a talented, hands-on, and experienced problem solver to join our highly skilled cross-functional engineering team as our first Data Scientist focusing on Marketing Analytics.

3. Data Analytics: Analyse large datasets to extract actionable insights on user behaviour, marketing campaign performance, and customer segmentation.
4. Marketing Optimisation: Collaborate with the performance marketing team to design and evaluate A/B tests, Lift Studies, and Incrementality testing that will optimise customer acquisition channels and improve conversion rates. Provide data-driven recommendations to enhance marketing ROI.
