Agentic Systems Full-Stack Software Engineer, Senior

AI summary of the role

Senior full-stack engineer for an agentic-first codebase where AI agents draft most code from specs you write, then you review, test, and ship it.

What you’ll do

  • Ship features end-to-end across ten Python/FastAPI microservices and a React/TypeScript front end, including DB migration, service logic, API contract, UI, and tests in a single change.
  • Author and maintain the agent harness (project instructions, skills, subagents, evaluations) that makes the codebase productive for AI agents.
  • Extend a multi-tenant authorization system modeled on AWS IAM with policy evaluation, guardrails, consent, per-service DB isolation, and audit trails.
  • Deploy and operate LLM inference on Kubernetes using vLLM on GPU nodes, Helm charts, model routing, and per-request cost accounting.

What you’ll bring

  • 5+ years full-stack development with a Python web framework (FastAPI, Flask, Django) and a modern JS framework (React, Vue, Svelte).
  • 3+ years cloud computing (AWS, GCP, Azure) and relational databases (schema design, query performance, versioned migrations).
  • 2+ years Kubernetes.
  • 1+ years agentic engineering with Claude Code, Codex, Cursor, or similar, including writing agent instructions and reviewing AI-generated code.
