Staff Software Engineer - Traffic Engineering - Remote

Overview

Toast creates technology to help restaurants and local businesses succeed in a digital world, helping business owners operate, increase sales, engage customers, and keep employees happy.

As a Staff Software Engineer on Traffic Engineering at Toast, you will design, build, and operate the traffic infrastructure that carries every request across Toast — from the public edge, through cloud networking, down to service-to-service routing. The team owns the systems that move traffic at Toast: edge and CDN, DNS, cloud networking, and the service mesh and control plane that route requests between services.

Toast has invested in a strong foundation of networking and platform infrastructure. This role is an opportunity to build on that foundation by evolving how services connect, route, and secure traffic at scale — making the platform faster, safer, and easier for service owners to depend on.

AI-assisted development is deeply embedded in engineering at Toast. The majority of engineers use AI tools daily, and AI agents participate in code review, build triage, and operational workflows. This is your chance to shape how the team's traffic platform evolves, building systems that empower both humans and agents to operate with speed and confidence.
