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