Senior/Staff Full Stack Engineer

Full Stack Engineer | San Francisco

Harrison Clarke is partnering with one of the fastest-growing AI companies in San Francisco. They are building the cloud agent operating system for knowledge work — one AI that replaces an entire stack of SaaS tools, and they're scaling the engineering team in SF right now to build it.

The role: This is a broad engineering role. Engineers follow important problems wherever they lead: interaction design, client architecture, APIs, data models, agent runtimes, and production operations.

The traction speaks for itself:

• 1,200%+ growth in 2026, $10M+ ARR and accelerating
• $42M+ raised, valued at $500M
• Founded by a repeat founder who previously built and exited incredibly successfully
• 12-person team in SF with engineers from Google, Amazon, and OpenAI

Requirements

• Bachelors in Computer Science
• Engineers who reason from first principles, ship with urgency, and care as much about why they're building something as how .

Intelligence, judgment, and product taste matter far more than stack matching. Open from mid-level to Staff+, but every role is hands-on IC — everyone builds and ships.

Compensation: $300K – $425K base + meaningful equity
