About the Role

Our client is hiring a Senior Founding Mobile Engineer to own and build their mobile product from the ground up. This is a true 0 → 1 role with real scale already in motion. You’ll define the mobile architecture, ship patient-facing features, and set the foundation for a world-class mobile engineering team.

This role is ideal for someone who has built and scaled consumer mobile apps, thrives with ownership, and wants to shape the technical direction of a mission-driven company at a pivotal growth stage.

What We’re Looking For

• 5+ years of mobile development experience for consumer apps

• Proven experience taking a mobile app from zero to one at a startup

• Experience scaling a consumer app to 10,000+ users

• Expert-level React Native + TypeScript

• Experience with native iOS (Swift) and/or Android (Kotlin)

• Strong understanding of mobile architecture and infrastructure

• Experience at a high-growth consumer tech company

• Ability to work independently with high ownership and accountability

• No visa sponsorship required (Canada/Mexico candidates may be considered case-by-case)

Nice to Have

• Prior founding-engineer or early-stage startup experience

• Experience working in regulated environments (healthcare, fintech, etc.)

• Interest in AI-powered consumer products

What We’re Not Looking For

• Candidates with only a pure Android or iOS background (no cross-platform experience)

• Background limited to large, slow-moving enterprise companies

• Engineers who prefer narrow scopes over ownership

Tech Stack

• React Native

• TypeScript

• iOS / Swift

• Android / Kotlin

• Expo (existing apps live on App Store & Google Play)

Why Join Our Client

• Founding Engineer Impact: Be the n=1 mobile engineer shaping the entire mobile platform

• Massive Scale: 100K+ members today, on track for 1M+ within 12 months

• Well-Funded: $35M raised from top-tier venture firms

• Mission-Driven: Build AI-enabled healthcare products that expand access to care

• Career Growth: Clear path to mobile team lead as the company scales

• Strong Leadership: Team includes senior clinical and technology leaders from top institutions
