What We're Looking For
We're looking for a Senior Product Security Engineer to lead product and cloud security by embedding into engineering workflows and acting as the subject matter expert for GCP. It involves running architecture reviews, leading threat modeling, and driving penetration testing engagements from scoping to remediation. The role also designs and enforces least-privilege IAM, builds security guardrails through policy and infrastructure-as-code, and ensures issues are triaged, tracked, and resolved. Beyond execution, it provides enablement and mentorship for engineers, clear documentation, and transparent reporting to security leadership.
What You'll Do
Run security architecture reviews for product features and our GCP environment in partnership with product and engineering; lead threat modeling and document risks, controls, and clear recommendations.
Own penetration testing engagements end‑to‑end: vendor/scoping, rules of engagement, test coordination, finding validation and severity, retest, and remediation tracking to closure.
Act as the GCP security SME for project teams, advising on secure patterns for networking (VPC, private access, perimeter controls), data protection (KMS, secrets), compute runtimes (GKE/Cloud Run/GCE), CI/CD (Cloud Build, Artifact Registry), and logging/monitoring.
Design and enforce least‑privilege IAM in GCP: role design (custom vs. predefined), service account lifecycle, workload identity, IAM Conditions, org/folder policy constraints, and periodic access reviews.
Triage and route product security related findings to the right engineering owners; tune rules to reduce noise, set severities and SLAs, and drive remediation - capturing justified exceptions.
Contribute security guardrails via policy and infrastructure‑as‑code (e.g., org policies, constraints, reusable Terraform modules, admission/policy controllers) and integrate pre‑merge checks in CI/CD.
Create practical documentation and runbooks (design review checklist, IAM standards, exception process) and deliver targeted enablement sessions for engineers and PMs.
Report progress and risks with metrics and status updates to security leadership; proactively escalate blockers and propose tradeoffs.Mentor engineers and code owners on secure‑by‑default coding and architecture best practices.
Minimum Requirements
5–7 years of experience in product security, cloud security engineering, or a related field.
Strong knowledge of Google Cloud Platform (GCP) services and security best practices, including IAM, networking, data protection, and workload runtimes.
Hands-on experience with penetration testing coordination, threat modeling, and risk assessment.
Proficiency with Infrastructure-as-Code tools (Terraform, policy controllers, CI/CD integrations).
Familiarity with designing and enforcing least-privilege IAM and conducting access reviews.
Ability to communicate security risks and recommendations clearly to engineering and leadership audiences.
Preferred Qualifications
Professional certifications such as GCP Professional Cloud Security Engineer, OSCP, or CISSP.
Experience building reusable security guardrails and automation at scale.
Familiarity with Kubernetes (GKE) and container security.
Prior success mentoring engineers or embedding security practices into development lifecycles.
Experience reporting security metrics and influencing technical and business decision-making.
