Role Overview

Support the Search Engineering team by managing vulnerability lifecycles, ensuring secure architectural practices, and overseeing automated fix validations.

Key Responsibilities :

Threat Modeling & Asset Profiling: Document trust boundaries, data flows, and architectural entry points for high-priority services; maintain up-to-date threat profiles in centralized repositories.

• Vulnerability Triage & Policy Management: Review and filter scanner findings, classify severity, and evaluate exception requests against security policies.
• Reproduction & PoC Validation: Construct minimal test environments/harnesses to validate reported findings and confirm viable vulnerabilities vs. false positives.
• Automated / Agentic Fixer Oversight & QA: Supervise and validate code patches generated by automated remediation agents, executing tests and inspecting diffs for regressions.
• Product Team Coordination & Closure: Route validated patches to code owners and shepherd fixes through code review to production deployment.

• Proficiency reading and writing code in at least two core languages (C++, Go, Java, Python) and building test harnesses/PoCs.
• Strong code review skills (identifying regressions, hallucinations) and knowledge of secure coding standards.
• Nice-to-Have / Advanced Skills:
• Experience with threat model reviews for large distributed / microservice architectures.
• Experience managing vulnerability queues, automated scanning tools, and compliance exception reviews.
• Practical experience with fuzzing, unit test frameworks, sandbox execution, and cross-boundary debugging.
