Our culture of trust, inclusivity, and empowered project management underpins everything we do, where each team member takes full ownership of their projects, from scoping and execution to postmortem. If you're seeking end-to-end ownership of your work, you've come to the right place!

Your Team and Role

Designing systems for improving our search indexes and AI features without compromising user privacy

Building new features on top of our Tracker Radar crawler to detect emerging privacy threats

Implementing new privacy features and maintaining existing ones, such as our Web Tracking and Email Protections

As a Senior Privacy Engineer , you'll own major components of our privacy technology, taking responsibility for their maintenance and improvement over time. A key part of the role will also be participation in our privacy review and audit processes, ensuring that all product developments align with our privacy principles. In time, you'll formally mentor other engineers, supporting their career growth and the growth of the Privacy Team at DuckDuckGo.
