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 Type Script

* 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)

* Type Script

* 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
