Senior Director, Infrastructure Architecture & Engineering
About the role
Senior Director, Infrastructure Architecture & Engineering
Five9 is investing in the leadership of its platform function. We want someone who runs this like a software product organization. Infrastructure architects who use code on the side won’t make it here.
You will have deployed platforms that real developers consume. Versioned modules. Real release cadence. Deprecation done right. Consumers who pin to interfaces because they trust them. You will have built and run end-to-end pipelines where build, test, security, deploy, observe, rollback, and upgrade are first-class concerns. If you spent your career drawing diagrams and handing them off, this isn’t the seat for you.
The infrastructure as a service (IaaS) platform function is being reshaped, the team is being built up, and modernization is already in motion. Today the platform work is fragmented across reporting lines and skill sets. The right person walks in expecting that, gets the urgent work stable, and starts shaping the team and the operating model on a clock we can measure.
This is a player-coach leadership role requiring strong technical judgment, hands-on engagement in architecture and engineering practices, and the ability to build teams and systems that scale beyond individual dependency.
What success looks like in your first 120 days
- A working map of the platform estate across our DCs and our cloud footprint, plus a clear-eyed read on the engineering practice you inherited and the team behind it
- A personnel evaluation and a product roadmap, written like a software roadmap and not an architecture deck, that shows how Five9 moves toward an Internal Developer Platform with paved roads, self-service, and end-to-end pipelines, sequenced against budget and the work that’s already running
