Founding Engineer

This is a rare, high-impact founding engineer position at an early-stage consumer AI startup building a real-time, AI-enabled platform to digitize human connection. You'll work directly alongside the founder — a Thiel Fellow — as one of the first engineers, shaping both the product and the engineering culture from the ground up. This is a fully on-site role in San Francisco.

You'll take on broad technical ownership across a bold consumer product focused on scalable, meaningful human interactions — integrating cutting-edge real-time video, audio, and memory systems.

What You'll DO

• Work across all aspects of the application alongside the founder, designers, and other engineers.

• Build new systems for memory, retrieval, proactivity, and AI responsiveness.

• Integrate the latest internal and external real-time video generation and audio synthesis models.

• Set the bar for engineering quality and help recruit world-class talent to the team.

• Dogfood the product extensively — you genuinely care about real user value and quality.

What We're Looking FOR

• Required:

• 2–7 years of software engineering experience (not a new grad — some professional engineering experience is required).

• Computer Science degree from a top-tier university.

• Strong CS fundamentals.

• High energy, exceptionally bright, and driven to build fast.

• Proven entrepreneurial spirit — startup exposure or experience in fast-moving, ambiguous environments.

• Track record of technically complex side projects or independent builds.

• Comfortable with — and excited by — early-stage chaos and the demands of a founding team environment.

• Nice to Have:

• Experience with real-time media, vision or video models, audio synthesis, or voice systems.

• Experience with memory and retrieval systems or agentic AI architectures.

• Proficiency in Python, including typed scientific Python.

• Familiarity with AI-assisted or agentic development tooling.

Compensation & Benefits

• Salary: $175,000 – $225,000 per year

• Equity as a founding team member

• Visa sponsorship available
