Founding Mobile Engineer (React Native / iOS)

Onsite – San Francisco (Pac Heights) · Full-time · $180K–$220K + Equity

About the Opportunity

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.

What You’ll Do

  • 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

What We’re Looking For

  • 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

AI-Native Engineering

We’re looking for engineers who are already operating in an AI-native workflow:

  • 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 Have

  • 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

Tech Stack

  • React Native (Expo)

  • TypeScript

  • Native iOS modules (Swift)

  • AI tools (Cursor, Claude, custom agents)

Location & Compensation

  • Onsite: San Francisco (Pacific Heights)

  • Work authorization: Open to H1B transfer only (no new sponsorship)

  • Compensation: $180K – $220K base + ~0.5% – 2% equity
    (flexible for exceptional candidates)

Interview Process

  • G2i video screening (4–5 technical questions)

  • 1-hour live coding/build session

  • (Optional) Founder interview (culture & fit)

  • 4-hour onsite build in San Francisco (travel covered if needed)

  • Offer

Timeline

  • Urgency: High (rolling process)

  • Candidate submission deadline: ASAP

  • Target hire date: As soon as the right founding-level candidate is identified
