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 (45 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
