Requirements
• 5+ years in application security, product security, or DevSecOps with a track record of shipping controls that earn adoption, not just approval. • Hands-on builder. You define secure patterns, write code, and deliver tooling that holds up in production. You're a practitioner, not just an advisor. • Experience conducting threat models and security architecture reviews across mobile (iOS/Android), cloud (AWS/GCP), and backend services (Java, Python, PHP). You catch design flaws that automated tools miss. • Practical experience securing AI/ML systems. You've worked with prompt pipelines, RAG architectures, model access controls, or agentic workflows and understand the trust, authorization, and data boundary problems they introduce. • Working knowledge of ASPM platforms and security tooling: SAST, SCA, secret scanning, container scanning. You've tuned these to produce signal, not noise. • Familiarity with CI/CD security integration. You've built security into pipelines without breaking developer velocity. • Solid grounding in secure development practices: OWASP Top 10, OWASP LLM Top 10, secure-by-design principles, and practical remediation guidance. • Comfort with ambiguity. You're energized by first-draft standards, testing approaches, and scaling what works rather than waiting for a playbook. • Strong cross-functional communication. You carry risk, tradeoffs, and technical decisions across engineering, product, and leadership without losing precision. You can reshape a risky decision clearly and constructively. • Experience with multi-agent orchestration frameworks and their identity and authorization challenges. • Background in consumer technology or privacy-sensitive domains where personal data is a core product obligation, not just a legal checkbox. • Experience securing location-based services or products involving data from minors. • CISSP, OSCP, GWAPT, or similar certifications. • Contributions to open-source security tools, public research, or conference speaking.
Responsibilities
• Security Partner Engagement • Conduct security architecture reviews across mobile (iOS/Android), backend (Java, Python, PHP), data pipelines, and third-party integrations. You're the security partner teams come to during design, not after. • Translate threat models and security requirements into pragmatic guidance engineers can act on. • Build trusted relationships with product and platform engineering teams • Tooling & Secure Defaults • Further operationalize and tune ASPM tooling (Cycode) to unify SAST, SCA, secret scanning, and container security into actionable signal, not noise. • Build security-as-code patterns and pre-approved libraries that make the secure path the default path. • Automate vulnerability triage, deduplication, and routing so the team spends time on judgment, not toil. • Vulnerability Management • Drive SLA-based remediation workflows with clear severity definitions, ownership, and escalation paths. • Build metrics that translate security posture into language engineering leadership and executives can use. • AI & Emerging Platform Security • Partner on design reviews for AI-powered features: model access controls, data boundary enforcement, and retrieval system authorization. • Contribute to securing agent workflows, MCP integrations, and shared AI tooling as adoption scales across engineering. • Work with Privacy, Legal, and Data Platform on controls for sensitive data: real-time location, family relationships, and data involving minors.
