Product Engineer

About primitive.dev

primitive.dev is building the communication layer for the agent economy. As AI agents increasingly act on behalf of people and businesses, companies need infrastructure to identify them, understand what they need, and interact with them at scale.

We rebuilt email from the ground up for machine-to-machine communication, optimizing the entire stack for latency, throughput, reliability, and developer experience. On top of that infrastructure, we deploy and operate agents for our customers. They begin as a general interface to the business, then learn from incoming traffic and create specialized agents to handle recurring workflows.

What you’ll do

Own the product through which non-technical teams create and operate agents. We let someone define a business outcome, deploy an agent, and improve it without ever seeing the engineering underneath. This role owns that abstraction across product, design, frontend, and backend.

What you bring

• You have built and shipped polished user-facing products end to end
• You are an excellent frontend engineer and can work across the backend when needed
• You can turn complicated systems and ambiguous customer needs into simple software

Nice to have

• Experience making technical systems accessible to non-technical users
• Experience with agents, workflow automation, or developer infrastructure
• Former founder

Full-time and in person in San Francisco, relocation fully covered if needed.
