About the Role 

We’re hiring a Mobile Engineering Lead to own the technical direction of our mobile applications. You’ll balance hands-on development with leadership—setting standards, mentoring engineers, and shipping polished experiences across iOS and Android. You approach mobile development as a craft, and you use every tool available—including AI—to elevate your team’s output. 

Our Stack 

• Mobile Framework: Expo (React Native) 

• Primary Database: Postgres

Responsibilities

• Integrate AI-assisted development practices into the team’s workflow 

• Collaborate closely with product, design, and backend teams to deliver cohesive experiences 

• Own mobile release processes, performance, and reliability

• *The company reserves the right to add or change duties at any time. 

Qualifications 

• 6+ years of mobile development experience with at least 2 years in a leadership capacity 

• Deep expertise with Expo and React Native - you know when to use managed workflow vs. dev builds, how to optimize bundle size, and how to debug native issues 

• Strong TypeScript proficiency 

• Experience integrating mobile apps with Postgres-backed APIs 

• Track record of shipping consumer-facing mobile applications at scale 

• Daily use of AI coding tools to accelerate development and code review 

• Familiarity with frontier LLMs and practical experience integrating them into your work

• Background in CI/CD for mobile, feature flagging, and phased rollouts (EAS Update, EAS Build) 

• Eye for design and user experience 

• Native iOS (Swift) or Android (Kotlin) experience for edge cases requiring native modules 

Skills 

• Relentlessly curious - you dig into new tools and technologies before they have comprehensive documentation 

• High agency - you don’t wait for permission or detailed instructions; you figure things out and drive forward 

• Comfortable with ambiguity - you can pick up bleeding-edge LLM tools and make them productive without hand-holding 

• Self-directed - you identify what needs to be done and do it
