Flo is the world’s #1 health & fitness app worldwide 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 7M 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 Senior Frontend Engineer to help us build the next generation of Flo’s platform and user experiences.
You’ll work on the foundation that powers interactive surveys and dynamic content inside the Flo app — building SDKs, reusable components, and internal tooling that enable other product teams to deliver exceptional experiences quickly and reliably.
Our frontend stack is based on React, TypeScript, and Next.js, with a strong focus on performance, maintainability, and testing.
We care deeply about quality: we use TypeScript for type safety, Jest and Playwright for automated testing, and continuously evolve our design system and UI Kit.

How we work
We’re a mission-led, product-driven team. We move fast, stay focused and take ownership – from brief to build to impact. Debate is encouraged. Decisions are shared. We care about craft, ship with purpose, and always raise the bar.
You’ll be working with people who take their work seriously, not themselves. It takes commitment, resilience, and the drive to keep going when things get tough. Because better health outcomes are worth it.
What you'll get
We support impact with meaningful reward. Here’s what that looks like:
Diversity, equity and inclusion
Our strength is in our differences. At Flo, hiring is based on merit, skill and what you bring to the role – nothing else. We’re proud to be an equal opportunity employer, and we welcome applicants from all backgrounds, communities and identities. Read our privacy notice for job applicants.
