• Threat model privacy concepts (consent, data sharing, data minimization, purpose limitation, retention, sovereignty, product privacy, etc.) into concrete adversarial scenarios, then design and execute red team engagements against those scenarios.
• Conduct deep, hands‑on technical assessments and penetration tests of internal and external-facing systems, products, and services, with a focus on bypassing user privacy expectations from the perspective of an external attacker.
• Identify exploitable issues across the data lifecycle – how data flows internally between services and how it is shared with external parties – and demonstrate impact end-to-end.
• Research emerging privacy threats and attack techniques; develop new testing methodologies and abuse cases ahead of them landing in production.
• Partner with engineering and product teams to integrate privacy-preserving controls throughout the SDLC, and translate findings into actionable, prioritized remediation guidance.
• Research and analyze emerging threats in privacy, proactively identifying mitigation strategies and testing methodologies to protect user data.
• Help shape the practices, processes, and documentation that define how privacy red teaming is done at Tik Tok, both internally and with cross‑functional working groups.
• Build tooling, scripts, and frameworks to scale privacy-focused assessments and automate recurring checks.

• Strong fundamentals in computer science, offensive security (especially appsec), security engineering, and privacy engineering.
• Ability to reason about privacy as an attacker: turning abstract concepts into concrete, testable abuse cases.
• Strong manual secure code review skills, with an eye for privacy-specific bugs in addition to traditional appsec issues.
• Comfortable working across heterogeneous stacks and unfamiliar codebases.
• Ability to operate independently, prioritize across competing engagements, and drive complex assessments to completion.
• Excellent written and verbal communication, with experience working cross‑functionally with engineering, legal, and compliance partners.

• Hands‑on experience as an offensive penetration tester / red teamer.
• Demonstrated depth in application security, mobile security pentesting, red team exercises, APT simulations, and cloud systems.
• Experience performing manual secure code review on production codebases.
• Track record of leading complex technical assessments end‑to‑end as an individual contributor – threat modeling, scoping, executing, and technical reporting.
• Working knowledge of core privacy concepts such as data minimization, data sovereignty, data sharing, consent, and privacy policies, and ability to translate them into security testing scenarios.
• Familiarity with major privacy regulations (e.g., GDPR, CCPA) and how they map to technical controls; ability to understand and apply foundational privacy concepts in a security testing context.

• Strong working knowledge of privacy concepts and ability to threat model around them to find privacy-specific vulnerabilities.
• Deep understanding and experience with common offensive testing frameworks such as MITRE ATT&CK and proficiency in a scripting language for tooling, automation, and code review at scale.
• Visible contributions to the security or privacy community – public research, talks, blog posts, bug bounty findings, CVEs, OSS tooling, etc.
