About the job

As a Customer Engineer, Agent Builder, you will be responsible for end-to-end execution of AI agent builds for strategic customers. This is a highly technical delivery role where you will own the implementation work required to launch and scale enterprise-quality agents—partnering with customers and internal teams to define success, translate requirements into build plans, and deliver agents that meaningfully impact the customer’s business.

Responsibilities

- Own end-to-end execution of AI agent builds for enterprise customers, from initial scoping through launch and iteration.

- Write and maintain key agent-building artifacts (e.g., AOPs), and configure agent behavior to optimize quality, reliability, and business outcomes.

- Configure and validate guardrails to ensure safe, compliant, and predictable agent performance across real-world scenarios.

- Set up, test, and validate customer integrations (e.g., ticketing systems), including building tools and workflows needed for successful deployments.

- Interface with senior technical stakeholders at customers to define success criteria, gather requirements, and drive delivery against timelines.

- Translate customer needs into clear internal documentation and run tight feedback loops with Engineering to drive platform improvements.

- Partner closely with APMs, Engineering, Design, and Go-To-Market teams to deliver consistent, repeatable, best-in-class agent builds.

Qualifications

Minimum

- Have 5+ years of relevant experience in a technical customer-facing role (e.g., solutions engineering, forward-deployed engineering, technical consulting, implementation engineering, technical product/PM, or similar).

- Strong technical foundation: comfortable writing code, working with APIs, and building/validating integrations end-to-end.

- Experience delivering production-grade customer solutions that require structured execution, testing/validation, and iteration.

- Ability to communicate clearly with senior technical stakeholders, translate requirements into implementation plans, and drive delivery.

- Comfort working in fast-moving, ambiguous environments where you shape solutions as much as you implement them.

Preferred

- Experience building with or around LLMs / AI agents (prompting, evaluation, guardrails, tooling, workflow design, etc.).

- Experience with enterprise SaaS integrations (e.g., ticketing systems, CRM, data pipelines) and associated security/compliance considerations.

- A Computer Science, Engineering, or Math degree, or equivalent technical experience.

- Strong product instinct: ability to write crisp PRDs, define success metrics, and contribute customer insight back into product roadmap.
