Senior C++ Engineer

Hi, we're Duck Duck Go , the online protection company and remote-first team of 400+ on a mission to raise the standard of trust online. Founded in 2008 and profitable since 2014, annual revenue now exceeds $100m USD and millions use our browser on Mac, Windows, iOS, and Android, our search engine, and the Duck Duck Go  subscription. We also offer private, useful, and optional AI, including Duck.ai,

which lets you chat privately with ChatGPT, Claude, and other AIs, all in one place.

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!

Working on the C++ Functional Team, you'll build the high-performance code at the core of Duck Duck Go 's browser using modern C++ and Chromium, and work on related projects.

• Implement tracker blocking that stops hidden trackers on every site without slowing page loads.
• Bring VPN and Personal Information Removal into the browser through the Duck Duck Go  subscription.
• Catch startup and responsiveness regressions automatically, so the browser stays fast as it grows.

As a Senior C++/Chromium Engineer, you'll lead complex projects from proposal through post-mortem. You'll turn vague problems into clear plans, build them in a large modern C++ codebase, and use metrics to show they worked. Some days that means low-level systems work. Others, it means architecture decisions the whole team builds on. You'll collaborate with design and product, mostly asynchronously, to build features people use to protect their privacy.
