Description

The role involves designing and building shared agent and Large Language Model tooling, including framework abstractions for tool use, retrieval, memory, and orchestration. The engineer will develop evaluation infrastructure for features powered by Large Language Models, such as offline evaluation harnesses, regression detection, and observability for production behavior. Responsibilities include partnering with product-facing teams to transition prototypes into production-ready systems while managing quality, latency, and cost. The position requires setting technical patterns and quality standards for how teams structure, evaluate, and monitor agents. Additionally, the engineer will collaborate with researchers and other engineering groups to integrate new capabilities into the runtime.

Required Qualifications and Skills

Candidates must possess at least three years of software engineering experience with a background in systems and Python. Required qualifications include experience shipping agentic or Large Language Model-powered features to production and designing developer-facing libraries or platforms. Applicants must hold or be in the process of obtaining a Bachelor's degree in Computer Science, Computer Engineering, or a relevant technical field. Additionally, hands-on familiarity with prompt design, tool use, retrieval, and evaluation is necessary.
