Responsibilities
•Build and ship full-stack product features based on customer needs, from initial discovery through production release.
•Develop agent-powered workflows and shared foundations for context, tool use, evaluation, guardrails, and observability.
•Make architectural decisions across frontend, backend, and infrastructure, considering performance, security, and developer experience.
•Review AI-assisted code and use frequent releases and customer feedback to improve product quality.

•Experience designing reliable LLM workflows with evaluation loops, guardrails, and observability.
•Strong foundations in databases, APIs, and full-stack architecture; experience with PostgreSQL, Supabase, Vercel, REST or GraphQL, and real-time data integrations is relevant.
