Platform Security Engineers (PSEs) focus on securing the internal infrastructure and platform systems that power our development and production environments. Working at the intersection of engineering and security, PSEs design, implement, and maintain scalable security controls across Kubernetes, AWS, Azure, MongoDB, CI/CD pipelines, and more.

They work closely with the Platform Engineering, Infrastructure, and GRC teams to ensure our systems meet regulatory and audit requirements (e.g., SOX, SOC 2) and that controls are practical and robust. PSEs also own the integration and configuration of SIEM log sources, ensuring high-quality visibility into system activity.

In addition, PSEs manage and deploy security tooling requested by the central Security team, including endpoint protection, cloud access security brokers (CASBs), and monitoring agents (e.g., CrowdStrike, Zscaler). They are responsible for both the technical configuration and platform-level deployment of these systems.

PSEs are hands-on engineers who treat security as an engineering discipline, prioritizing automation, testing, observability, and scalability in everything they build.
