About the team

Coupa's Supplier Portal (CSP) is the network where 10M+ buyers and suppliers transact. We're building agents that act on behalf of suppliers on that network — processing invoices, enriching catalogs, answering strategic questions, and helping suppliers get discovered by buyers.

The team is small, senior, and moves fast. We embed across product surfaces to identify where agents solve real problems. We operate at the frontier of what’s possible, finding where technology meets customer needs, often before it appears on the roadmap. We believe the harness is the product.

About the role

We're looking for a Senior Software Engineer to be the durable technical owner of the platform our supplier agents run inside. This is first and foremost a strong software engineering role — you'll design and build reliable backend services, the tool layer that wraps Coupa APIs for agent use, the execution environment that keeps supplier data isolated, audit and replay logging, and the pipeline that gets it all to production. We are hiring for engineering judgment and the ability to design, build and ship dependable systems. Familiarity with LLM-based systems.

You'll start as a strong IC partnering with the team lead on architecture, and we expect you to ramp quickly into owning core platform design yourself. This is a role for someone who wants ownership of a foundational system at the moment it's being built.
