Founding Mobile Engineer (React Native / iOS) - On site in San Francisco!

G2i Inc. • San Francisco, CA

28d • Onsite

About The Position

G2i is partnering with a fast-growing, early-stage startup to hire a Founding Mobile Engineer. This is a rare opportunity to join as the first mobile engineer, working directly with the founders to build and scale a consumer-facing product from the ground up. You won’t be joining a team — you’ll be defining it. This role is ideal for someone who thrives in 0→1 environments and wants full ownership over the mobile experience.

Requirements

• Proven experience building and shipping mobile apps end-to-end (0→1)
• Strong expertise in React Native (Expo) and TypeScript
• Experience working with or integrating native iOS modules
• Deep focus on UI/UX quality, interaction design, and performance
• Strong product intuition — you think beyond implementation
• Ability to move fast without compromising quality
• High ownership mindset — you proactively identify and solve problems
• Strong communication skills and ability to work closely with founders
• Actively use tools like Cursor, Claude, or similar in daily development
• Understand tradeoffs of AI-assisted coding
• Can clearly articulate when and how to leverage AI effectively
• Continuously explore ways to increase output and quality using AI

Nice To Haves

• Experience building consumer (B2C) products
• Strong mobile design intuition and attention to detail
• Background in high-performance mobile applications
• Side projects or products you’ve built independently

Responsibilities

• Own the mobile app end-to-end — from concept to production
• Build high-quality, intuitive, and performant user experiences
• Ship features rapidly and iterate based on real user feedback
• Collaborate directly with founders on product direction and priorities
• Optimize performance across animations, rendering, and interactions
• Debug and resolve issues across the stack when needed
• Leverage AI tools to accelerate development and improve output quality

Benefits

• Equity
• Travel covered if needed for onsite build
