This is a rare opportunity to join as a Founding Product Engineer within a small, high-trust team where engineering quality, product instinct, and design taste matter deeply.

• Clear understanding of high-quality UI and product experience
• Portfolio or prior work demonstrating strong engineering and product taste
• Based in San Francisco or willing to relocate immediately
• Comfortable working onsite 5 days per week
• Existing US work authorisation (no sponsorship available)

Nice-to-Have

• Previous startup, founding engineer, or YC-stage experience
• Experience within:
• GTM platforms
