Manager, Security Engineering

About SiTime SiTime is the Precision Timing company. Timing is the heartbeat of all electronics, ensuring performance, resilience and scalability. For decades, quartz devices, non-silicon technology, have kept systems in sync, but they struggle in harsher, more demanding environments. MEMS-based Precision Timing delivers greater accuracy, smaller size and resilience. Today, MEMS timing powers over 400 applications, including high-growth ones in AI datacenters, automated driving, industrial and humanoid robots, wearables and IoT. Our semiconductor MEMS programmable solutions offer a rich feature set that enables customers to differentiate their products with higher performance, smaller size, lower power, and better reliability. With more than 4 billion devices shipped, SiTime is changing the timing industry. For more information, visit: www.sitime.com . Job Summary Reporting to the CISO, this role builds and leads SiTime's Security Engineering function — the team that owns the company's security tooling from design through operation. It owns endpoint and network detection platforms, data protection and classification, privileged access, AISPM platform, Cloud and SaaS posture, and the hardening baselines that everything else depends on. This is a build role. Security Engineering will work closely with IT Engineering which owns the enterprise platforms used for productivity, identity and endpoint management. Security Engineering owns the security-specific stack, defines the control requirements that IT implements, and proves that the resulting coverage and configuration are actually effective. The two functions are joint execution partners. It is also a people-leadership role. The candidate starts hands-on, delivering the first deployment of each platform, then scales the function through a mix of full-time engineers and specialist contractors engaged for implementation projects. This is an accountable owner role, not an advisory one. The role partners with IT, Engineering and the CISO's other functions (Vulnerability Management and Security Operations; Security Risk, Assurance and Trust; Security Architecture; and Offensive Security) to turn control requirements into deployed, measured and maintained technology. We value diverse experiences, perspectives, and career paths, and welcome candidates who are excited to contribute to our mission. Security Platform Engineering - Build, Integrate, Operate Own the security tool estate end to end: architecture, deployment, configuration, integration, upgrade and lifecycle management. Operate and mature the existing stack, from deployment into steady-state operation with Security Operations. Drive coverage to a defined standard and prove it, no unmanaged endpoints, servers, cloud workloads or laboratory systems, with evidence rather than assumption. Build and maintain integrations and automation between security tooling, IT service management, identity and…
