Most of what Go-to Market teams do all day isn't selling. It's research, list-building, follow-ups, and data entry — work that should never have been a human job in the first place.

We're building a system of AI workers that own GTM execution end-to-end. Alice creates demand, and Julian captures it. They take the busywork off the table so GTM teams can can do what they do best: building relationships and closing deals.

Backed by $75M+ from a16z and Benchmark, headquartered in San Francisco, and trusted by Checkr, Xerox, Sage, and Armanino. We're hiring ambitious people who want to define how the next generation of companies accelerate growth.

What You’ll Do

• Design, build, and iterate on fullstack systems that power AI agents from concept to deployment
• Research and evaluate new approaches to agent orchestration, prompting strategies, and model alignment
• Collaborate with product, design, and GTM teams to improve UX and usability for non-technical users
• Share learnings, document findings, and contribute to the evolution of internal best practices
• Participate in peer reviews, brainstorming sessions, and technical deep dives with our global team

Ideal Candidates Have

• 3+ years of experience in a product-oriented software engineering role
• A CS/Engineering degree & professional experience; bonus if you’ve worked in a startup, consulting, or customer-facing technical role before
• Strong programming fundamentals in Typescript, React, NextJS, and NodeJS
• Familiarity with APIs, data flows, and debugging live systems
• Interest in AI/ML, conversational AI, or voice technologies
• Responsive and proactive in addressing customer needs with bias for action - comfortable shipping quickly and improving continuously in live deployments
