  , 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

• Background in high-performance mobile applications
• Side projects or products you’ve built independently

• React Native (Expo)
• Type Script
• Native iOS modules (Swift)
• AI tools (Cursor, Claude, custom agents)

• 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)

• 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
