About the role

  • You are equally comfortable writing agent orchestration logic, designing REST APIs, and shipping a React dashboard.
  • We want engineers who have closed the loop from prototype to production with AI systems that real users depend on.

Responsibilities

  • Design, implement, and deploy production-grade AI agents: multi-step reasoning pipelines, tool-calling workflows, multi-agent coordination, and human-in-the-loop handoffs
  • Design and build agent harnesses - the runtime infrastructure (context management, tool definitions, memory, feedback loops, observability, and lifecycle control) that makes agents reliable in production
  • Implement production-grade reliability: retry logic with backoff, cost controls, structured output validation, sandboxed tool execution, and checkpoint-resume for long-running agent workflows
  • Develop systematic evaluation frameworks (evals, golden datasets, regression suites, observability traces) that measure agent quality and catch regressions before production
  • Architect and implement scalable backend services and APIs (REST/GraphQL) in Go, Rust, or TypeScript/Node.js
  • Build and maintain integrations with external systems - databases, internal APIs, robot data streams - enabling agents to take real actions with appropriate access controls
  • Own deployment, monitoring, and observability: Docker, Kubernetes, CI/CD pipelines, and LLM-specific tracing and cost tracking
  • Build clean, functional web interfaces in React/Next.js - operator dashboards for robot fleet management, engineering tooling for the AI team, and customer-facing applications

Requirements

  • 5+ years of professional software engineering experience with a full-stack production track record - this is a software engineering role first
  • strong fundamentals in system design, data structures, algorithms, and code quality are required
  • Frontend engineering proficiency: React, Next.js, TypeScript - able to architect and ship functional, production-grade UIs, not just wire up component libraries
  • Experience with at least one LLM API (Anthropic Claude, OpenAI, or equivalent) and agentic frameworks (LangChain, LangGraph, PydanticAI, or similar)

Nice to have

  • Experience with durable execution patterns (Temporal, or similar) for long-running or stateful agent workflows with checkpoint-resume
  • Vector database and embedding experience (Pinecone, Weaviate, pgvector, Voyage AI, etc.) - but as one tool in a broader context engineering stack, not the whole solution
  • Experience designing multi-tenant platforms or internal developer platforms (SDKs, golden-path tooling, shared infrastructure)
  • Familiarity with prompt injection risks, sandboxed code execution, and AI security considerations for agents that take real-world actions
