## Job Description

## Responsibilities
- Co-architect and co-build production AI agents with customer engineering teams.
- Own the technical win in pre-sales by designing proofs of concept, answering deep technical questions, and guiding evaluations.
- Help customers deploy and operate agent-based applications, including conversational agents, research agents, and multi-step workflows.

- Comfortable working directly with customers during proofs of concept, architecture reviews, and technical evaluations.
- Able to explain technical tradeoffs clearly and build trust with developer audiences.
- Ownership of outcomes, not just recommendations.
- Bias toward action and comfort figuring things out as work evolves.
- Interest in operating AI agents in production, not just building demos.
