Senior Staff Software Engineer, Gusto Agent & Partner Experiences (API)

As a Senior Staff Software Engineer on the Agent & Partner Experiences team, you'll be a key technical leader responsible for influencing the team and broader organization as we build and scale our platform. You'll do this through a combination of hands-on development in our complex Ruby on Rails codebase and guiding others to deliver a high quality platform experience. You’ll sit at the bridge between our API and AI world - turning a payroll platform built for developers into one that agents can reason about and act through.

Gusto Agent & Partner Experiences is a platform that allows developers to embed payroll directly into their own software using our APIs and allows AI agents to act on payroll on a customer’s behalf. We've taken Gusto’s robust payroll infrastructure and made it available beyond Gusto itself - to third party developers and to the agents acting on their customers’ behalf. Our vision is to enable anyone to build the best payroll product for their end customers - powering payroll for small and medium businesses across a variety of industries, from vertical SaaS to fintech and neobanks to AI-native products.
