Senior Staff Software Engineer

At Flo. Qast, we aren't just building tools; we are crafting the "Operating System for Accounting." As a Senior Staff Software Engineer on the Close team, you are a primary architect of this vision. This is a role for a technical visionary who thrives on solving "impossible" distributed systems problems and understands that the best code is the kind that empowers an entire engineering organization to move faster.

You won't just be "coding"—you’ll be defining the technical North Star for Flo. Qast Close, our centralized hub where accountants can create, test, deploy, and manage bespoke AI Agents. You will drive step-function improvements in how we deliver our Visual Agent Builder and empower global brands to automate complex workflows without touching a line of code.

This is expected to be hybrid in our San Jose office.
