About Our Client
Our client is a fast-growing AI technology company transforming the food distribution industry through intelligent automation. Their AI-powered platform helps food distributors automate critical workflows across sales, operations, procurement, credit control, logistics, and supply chain management. Built by industry experts with deep experience in food distribution, the platform enables distributors to reduce manual work, improve efficiency, and scale their operations more effectively.
The Opportunity We are looking for a Senior Full Stack AI Engineer. You will design, build, and ship the agents described above and the platform they run on. The work spans the full stack: React interfaces, NestJS services, AWS infrastructure, and the eval and feedback systems that determine whether an agent is actually performing. Everything you build goes into production for customers moving real product on real deadlines.
This is a role for an engineer who wants ownership of systems that carry a customer’s daily operations, not a research position and not a prompt-engineering position.
Requirements
5+ years of experience with Node.js, TypeScript, and React in production
At least one AI agent built, deployed, and running in production, beyond the prototype stage
Applications deployed on AWS and serving real traffic
Hands-on experience with LLM and agent frameworks such as LangChain or LlamaIndex
Production use of observability tooling such as Datadog, OpenTelemetry, or CloudWatch
Experience designing eval frameworks for AI systems and building self-learning or feedback-loop systems
Direct experience managing production incidents end to end, from detection through resolutionThe ability to clearly articulate and defend system design decisions you personally made
Active use of AI coding tools such as Cursor, Claude Code, or Copilot to increase output, grounded in a track record of writing production code before LLM-assisted development existed
Responsibilities
Production AI agents that run operational workflows end to end for food distributors
Full-stack features in TypeScript, NestJS, and React, shipped to production and maintained there
Eval frameworks and feedback loops that measure and improve agent performance over time
Large-scale order, catalog, and operational data at the application layer
AWS infrastructure (Lambda, ECS, RDS, S3) managed with Terraform
Observability as a first-class concern, with logging, tracing, and alerting built in from the start
Opportunity Details
Full-time, permanent position
Based in San Francisco, CA - reallocation covered
