The Job The Security Engineer II will help design, build, and scale the security foundations of our products, infrastructure, and engineering systems. This is a hands-on technical role for an engineer who can move across software development, network security, cloud and infrastructure security, and security architecture while partnering closely with engineering teams to identify risk and build practical, durable solutions. You will strengthen security through engineerin g, writing production-quality code, improving platform controls, automating security processes, shaping secure architecture, and embedding strong practices into the software development lifecycle. The ideal candidate combines deep security judgment with strong software engineering fundamentals and can improve security without creating unnecessary friction for developers or slowing product velocity. Responsibilities Design, implement, and maintain security controls across applications, cloud infrastructure, corporate networks, and internal engineering systems. Partner with engineering and infrastructure teams to perform threat modeling, architecture reviews, and security assessments for new products, services, and critical systems. Build security tooling, automation, and guardrails that improve vulnerability detection, prevention, remediation, and developer self-service. Develop and operate SASE, Zero Trust, VPN, and secure remote-access capabilities using identity, device posture, least privilege, and application-level access controls. Strengthen foundational cloud and platform security controls, including IAM, secrets management, CI/CD security, workload protection, logging, and secure configuration. Assess and mitigate security risks associated with AI-enabled applications, agents, models, APIs, and third-party AI platforms, including prompt injection, data leakage, insecure tool use, and unauthorized actions. Develop security controls and engineering standards for AI systems, including model and data access, input/output validation, sensitive data protection, monitoring, isolation, and abuse prevention. Investigate security incidents and anomalous activity, support incident response and root-cause analysis, and translate findings and emerging threats into durable improvements to security architecture and engineering practices.
