Senior Lead Software Engineer, AI Systems- 11509
-
Design and build the backend services behind the agent platform — the tool layer over Coupa APIs, context/state management, and the execution environment that keeps supplier data isolated.
-
Build the evaluation and logging pipeline: how we measure behavior, catch regressions, and turn production failures into fixed behaviors.
-
Partner with product and engineering to ship the first supplier-facing use cases (invoicing, catalog, strategic views) on the platform you build.
-
Own how the platform reaches production — deployment, configuration, scaling, and staying secure.
-
Make architectural calls on runtime isolation, credential handling, audit logging, and tenant separation.
-
Raise the engineering bar for the team — code quality, testing, and operational discipline.
Have 6+ years shipping production software and are strong in Python (TypeScript a plus).
Have built and operated services on a major cloud (AWS preferred) — containerized deployments, IaC, and the day-two work of keeping them running.
Have built backend services, platforms, or infrastructure that other engineers or systems depend on — APIs, SDKs, runtimes, internal platforms.
Have operated what you've built in production: you understand reliability, observability, failure modes, and least-privilege security, not just the application layer.
Write clean, well-tested code and reason about latency, failure modes, and user outcomes together, not as separate concerns.
Write and speak English fluently — the team operates in English and the work is prose-heavy.
Are comfortable working near LLMs — you don't need to have shipped an AI agent, but you should be curious about the space and quick to pick it up. Familiarity with LangChain / LangGraph or similar agent frameworks is a plus.
A public GitHub, blog, or portfolio we can look at (strongly preferred — it's the fastest way for us to see how you think).
Are a daily user of agentic coding tools (Claude Code, Cursor, Codex, or equivalents).
Have shipped an LLM-powered feature or product, and have opinions about why most of them don't work.
Experience with agent frameworks, eval tooling, or production LLM observability.
Hands-on with our specific stack — AWS Bedrock / AgentCore, LangGraph, or comparable managed-LLM and sandboxed-execution infrastructure.
Experience in procurement, fintech, or another regulated enterprise domain.
