Job Description

400M+ downloads. 75M+ monthly users. A decade of building - and we're still accelerating.

Flo is the world's #1 health app on a mission to build a better future for female health. Backed by a $200M investment led by General Atlantic, we became the first product of our kind to reach a $1B valuation in 2024 - and we're not slowing down.



With 6M paid subscribers and the highest-rated experience in the App Store's health category, we've spent 10 years earning trust at scale. Now, we're building the next generation of digital health - AI-powered, privacy-first, clinically backed - to help our users know their body better.

The job

We're looking for a talented ASO Specialist to join our team and play a pivotal role in driving Flo's organic growth. If you're passionate about mobile app discovery, data-driven optimization, and creating impactful user experiences, we want to hear from you.

Using a mix of data points and sources, your insights will directly inform and adjust our ASO plans and priorities. Executing ASO Initiatives: You'll lead the day-to-day operational efforts in ASO's ongoing optimization. This includes discussing action plans with the team, uploading assets to developer consoles, and configuring various store listings and experiments.
