• 5 years of experience with security engineering, computer and network security, and security protocols.
• 5 years of coding experience in one or more general-purpose languages.

• Proven expertise in performing complex threat modeling for large-scale distributed systems and conducting attack path modeling and simulation to identify non-obvious lateral movement and indirect access risks.
• Technical knowledge of system hardening techniques across various layers (OS, network, and application) to enforce security invariants and reduce the attack surface of critical production services.

About the Job

Our Security team works to create and maintain the safest operating environment for Google's users and developers. Security Engineers work with network equipment and actively monitor our systems for attacks and intrusions. In this role, you will also work with software engineers to proactively identify and fix security flaws and vulnerabilities.

PRISM is the central engineering team responsible for the reduction of Production Infrastructure Access Abuse risks, which is driven through the collection of INTACT programs, including User Data Protection (UDP), AI Model Oversight, Access and Tooling (MOAT), Malicious Outages (MalOut), and Trusted Core Access (TCA).

We are looking for a Security Engineer who is interested in working on security research and risk mitigation systems, help scope security problems, and contribute to projects within Privacy, Safety, and Security (PSS) and across Product Areas (PAs) to transform how Google manages and eliminates internal access risk.

As a Security Engineer on the PRISM team, you will be at the forefront of redefining Google's internal access landscape. You will not just be responding to risks; you will be anticipating them by building the next‑generation taxonomy of access risk and architecting 'secure-by-default' solutions that protect our most critical infrastructure. From modeling complex attack paths to securing the rise of agentic identities, you will lead projects that transform how Google proactively manages risk at an enterprise scale.

Compensation

Individual pay is determined by factors including job‑related skills, experience, and relevant education or training.

• US: $174,000 - $253,000 (USD) + 15% bonus target + equity + benefits
