Job description

Harrison Clarke is partnering with one of the fastest-growing AI companies in San Francisco to hire exceptional Software Engineers.

This company is building the platform that replaces traditional workflow automation with AI agents that actually do the work. Describe what you need in plain English and the agent figures out how to execute it across your tools, systems, and data, running 24/7 in the cloud.

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

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.

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: $220K – $400K base + meaningful equity
