Co-Founder and CTO

About the role

This is a true co-founder seat — not a senior hire executing a predetermined roadmap. As an equal co-founder and CTO, you will own the research agenda, shape the product vision, and build the technical team at an early-stage AI video advertising platform with real traction, a running flywheel, and several consequential technical decisions still deliberately open for you to make.

Responsibilities

• Define and drive the company's core research agenda and long-term technical strategy.
• Own product direction end-to-end, from architecture through to user-facing features.
• Make significant, open-ended technical and product decisions independently and with authority.
• Build and lead the engineering team as the company scales.
• Collaborate as an equal co-founder on overall company direction, culture, and strategy.

Requirements

• 4–16 years of experience in technical roles, with demonstrated leadership at a senior or founding level.
• Exceptional engineering ability and comfort operating at both a strategic and hands-on level.
• Background in AI, machine learning, or generative video/media systems is highly relevant.
• Track record of making high-stakes technical decisions with real ownership and accountability.
• Thrives in an ambiguous, fast-moving environment where key decisions remain open by design.
• Able to commit fully (full-time, 6–7 days per week) and work in person in San Francisco.

Benefits

• Equity: Equal co-founder equity (~28%).

Visa sponsorship is not available. On-site in San Francisco, CA; in-person presence is required.
