Senior Mobile Engineer (React Native)

Receipts is creating a new economy around fitness and wellness—one that rewards people for consistent physical activity while giving brands a proper channel to engage with core customers.

Today, 1 in 4 adults fail to meet the minimum physical activity guidelines set by the World Health Organization, making inactivity the fourth leading risk factor for global mortality. Simultaneously, fitness and wellness brands collectively invest ~$280 billion annually to attract and retain customers. However, most of these brands struggle to gain meaningful insights, establish targeted and engaged communication channels, or connect with their most active (literally) and high value customers.

We authenticate heart rate data through wearables and smartwatches (proof of workout). Based on the minutes spent at an elevated heart rate each week, users earn points that may be redeemed for exclusive perks and experiences, both within our app and through our partners.

We’ve been described as “Strava with points”, “Duolingo for fitness” and “credit card points for health and wellness”.

While our product is still in its early stages, we've already partnered with leading brands like Garmin and On Running, and are primed for significant growth 📈.

Our team is small but highly capable: we are a group of passionate athletes, every engineer on our team is a senior or staff-level Swiss army knife.

Receipts is well-funded and backed by top-tier funds and influential angel investors in crypto/blockchain.
