Location: Vietnam (GMT+7) Remote: Yes — daily overlap with US-Eastern mornings (~9:30am–1:30pm ET) Willing to relocate: No (remote only) Technologies: Python (10+ yrs) — Django/DRF, FastAPI, Celery · LLM agent orchestration (LangGraph, MCP, Claude Code/Codex/Antigravity, Gastown, Openclaw) · RAG (pgvector + Cohere) · workflow automation (n8n, ComfyUI) · PostgreSQL/Redis · Docker, GitHub Actions · Playwright · Stripe Senior backend/AI engineer. For the last two years I built and ran autonomous coding agents in production: they pick up bug reports, reproduce, fix, write tests, and open PRs - engineers review instead of writing. The same multi-agent harness now runs a fully automated content platform (five sites, no human in the publish loop). Before LLMs: cryptocurrency exchanges, an end-to-end ML training platform, and 10 years mentoring at Vietnam's biggest Python community (Pymi.vn). What I care about: agent infra where correctness and observability actually matter — building systems where an agent can be wrong without being dangerous (credential isolation, sandboxed tools, review gates). Contract or full-time.
