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

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.

• →

  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

• 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

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

• 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

• React Native (Expo)

• TypeScript

• Native iOS modules (Swift)

• AI tools (Cursor, Claude, custom agents)

• 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

• Urgency: High (rolling process)

• Candidate submission deadline: ASAP

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

G2i connects top-tier engineers with high-growth companies through a rigorous, developer-first hiring process. We focus on long-term fit, technical excellence, and impactful roles.
