Backend Software Engineer - Offense & Defense - PDPO

The Privacy and Data Protection Office (PDPO) leads and supports TikTok's global privacy efforts, making sure privacy is protected across our products, platforms, and technologies. As a technical privacy center of excellence, we partner closely with engineering, product, legal, and compliance teams to identify privacy risks and design effective technical safeguards throughout the software development lifecycle.

At TikTok's scale, protecting user data means going beyond compliance to find complex privacy vulnerabilities and emerging risks across highly distributed products and systems. We combine privacy engineering, security engineering, penetration testing, red teaming, and secure code review to surface those risks, develop mitigations, and build scalable automated assessment capabilities that protect privacy without slowing product innovation.

You will work at the intersection of privacy, security, and engineering, on real-world privacy challenges at global scale, influencing how privacy is built into products from the ground up.
