Work History
Senior Manager, Product Security
Atlassian
San Francisco, CA
05.2020 - Current
- Lead and grow a team of 12 security engineers (Principal Engineers to new grads). Set goals/expectations, career development plans, and delivery accountability across multiple workstreams.
- Owned and scaled security for the Atlassian Marketplace from the ground up — covering 7,000+ apps built by 1,000+ external entities — establishing platform-level security posture and enforcement mechanisms at scale.
- Built and scaled end-to-end programs spanning vulnerability detection, vulnerability management (triage, prioritization, SLAs/workflows, partner communications, remediation) and governance.
- Achieved 100% automated security scan coverage across the Marketplace using in-house-built tooling; applied risk-based routing to ensure findings translate into remediation and durable guardrails.
- Owned offensive coverage strategy for the Marketplace: bug bounty + pentest coverage ~40%, prioritizing high-risk apps and sensitive surfaces to maximize risk reduction and signal quality.
- Introduced threat modeling and security review gates for high-risk app categories and sensitive data access patterns.
- Built and operationalized governance programs including KYC/KYB for third-party entities — defining policy, controls, workflows, and cross-functional operating cadence to reduce fraud/abuse risk and improve ecosystem trust.
- Expanded security controls and guardrails to cover AI agents and GenAI product capabilities; directed Principal Engineers while partnering closely with Engineering Managers and GenAI teams to scale secure patterns across orgs.
- Supported GenAI engineering teams through security consultation and threat modeling to deliver enterprise-grade AI, focusing on: tool access boundaries, data isolation, workflow orchestration risks, abuse/misuse scenarios, logging/monitoring expectations, and safe rollout practices.
- Influenced senior stakeholders by communicating risk, tradeoffs, and strategy clearly — aligning security outcomes with business goals and product velocity.
- Led cross-functional teams to enhance product development processes and align strategic objectives.
Senior Cybersecurity Engineer
Visa
Foster City, CA
02.2015 - 05.2020
- Built a vulnerability risk scoring model to quantify risk across assets and drive consistent, risk-based prioritization and remediation decisions.
- Performed threat modeling and security architecture/design reviews early in the SDLC to prevent vulnerabilities pre-release (shift-left).
- Led/ran SAST, DAST, and penetration testing; produced actionable findings and partnered with engineering teams to drive fixes before launch.
- Contributed to AppSec standards and scalable security review practices across teams through hands-on partnership and enablement.
