We are looking for a Staff Engineer, Cloud Security to expand the scope and coverage of our cloud security capabilities. You will join an existing cloud security team and take a role in setting direction for how Toast secures its cloud environments.

A day in the life (Responsibilities) • Own and operate our Cloud-Native Application Protection Platform (CNAPP), including tuning, coverage, integrations, and turning findings into prioritized, actionable work for engineering teams. • Lead cloud security posture management (CSPM) across our AWS organization and accounts, defining standards and measuring adherence over time. • Drive identity and access management improvements, including least privilege, role and permission design, and reducing standing access. • Secure our container environments, from image and workload security to cluster configuration and runtime protection. • Build guardrails and secure defaults into infrastructure as code and deployment pipelines, so that teams get secure configurations by default rather than through review. • Perform secure architecture reviews and threat modeling for new and existing cloud services and platform capabilities. • Partner with our SOC on cloud detection coverage, logging, and investigation readiness. • Run and improve cloud vulnerability and misconfiguration remediation programs, working with engineering owners to drive risk down. • Participate in security incident response, including on-call coverage, and lead the cloud side of investigations and follow-up work. • Set the multi-year direction for cloud security at Toast, and mentor and uplevel other engineers on the team. • Build trusted relationships with Platform, Infrastructure, and product engineering leaders, and influence their priorities through data and clear risk communication.
