Member of Technical Staff, Full Stack

About the Role

Join a small, technical AI team building infrastructure that helps enterprise AI agents improve over time. This backend-leaning full-stack role focuses on the systems that evaluate agent performance, identify issues, and improve the knowledge and workflows agents rely on.

What You'll Do

• Build and improve backend systems for agent evaluation and continuous improvement.

• Develop data models for evaluation datasets, experiment runs, agent traces, knowledge versions, findings, and customer-defined quality criteria.

• Own enterprise integrations across authentication, OAuth, webhooks, data syncs, backfills, rate limits, retries, monitoring, and production support.

• Take features from technical design through implementation, deployment, monitoring, customer feedback, and iteration.

• Work with customers to understand their systems, diagnose failures, and turn specific needs into reusable product capabilities.

What We're Looking For

• Three to six years of experience as a backend-leaning full-stack software engineer, with substantial backend ownership.

• Experience building production systems for enterprise customers, including data models, pipelines or queues, and integrations.

• Comfort shipping user-facing features with TypeScript and React; Python experience is preferred.

• Familiarity with relational and vector databases and cloud environments.

• A bachelor's degree in computer science or a related field.

• Experience with AI agents, LLMs, evaluation, or quality assurance is beneficial.

• US work authorization is required. The role does not provide visa sponsorship or visa transfer.
