Company mission
To fix the web by giving users a safer, faster and better browsing experience - while growing support for content creators through a new attention-backed ecosystem of rewards.
Role
Who you are
- Proficiency in JavaScript. At least 3 years of experience is preferred
- Familiarity with the adblocking and filter list ecosystem (or willingness to learn)
- You know your way around DevTools for reverse-engineering websites, debugging code, and figuring out how web apps tick
- Very comfortable working and communicating async with a geographically-distributed team
- Proficiency working with Git and comfortable collaborating on GitHub
Desirable
- Experience with adblocking rules and filter lists
- Experience reverse-engineering complex JavaScript on (adversarial) websites
- Experience participating in open source communities (almost all of our work at Brave is done in the open on GitHub)
- Ability to handle conflict in face of competing priorities
- Familiarity with Web technologies and the Web security model
- Be excited about privacy, anonymity, and a user-first Web!
What the job involves
- Important: this is not a classic software engineering role. Maintenance, debugging and fast fixes via adblock rules are a big component of this job. You will be spending most of your time making sure websites work on Brave browser, shipping blocking rules that make users’ lives easier and safer (example: cookie consent notice blocking), and coming up with clever ways of countering adversarial websites that discriminate against Brave’s mission of a user-first Web for all
- Brave benefits greatly from open-source adblocking work, and a huge part of our ethos is contributing the work that we do back to the adblocking community. We work closely with filter list authors across the board. Most of the work in this position is expected to be open-source; your work will have a Web-wide impact on a daily basis. See our USENIX talk on how we scaled adblocking to millions of users
- Creating and maintaining Brave’s adblock rules and shipping fast fixes for breaking websites (we do multiple automated deployments an hour!)
- Reverse-engineering and debugging parts of the Web (HTML, CSS and especially JavaScript) that interact badly with Brave’s third-party adblocking
- Contributing to open-source adblocking projects like EasyList or uBlock Origin and making sure Brave users are getting the best ad & tracker blocking experience possible
- Monitoring and addressing feedback from the community by creating fixes to resolve user-submitted reports
- Helping the privacy team to come up with novel ways of solving webcompat issues categorically. For example: Cookiecrumbler
Our take
Brave, one of the most secure browsers on the market, has quickly built a reputation as a privacy-first champion. Free to use, it stands out for its commitment to blocking intrusive ads and trackers, while also offering a unique twist: users who opt-in can earn rewards by viewing privacy-respecting ads.
The browser's popularity has surged, particularly in 2024, as it continues to tackle the everyday annoyance of web browsing. One of its latest innovations, blocking cookie consent popups, has struck a chord with users fed up with endless prompts.
With nearly 80M monthly active users, Brave is proving that privacy and speed can go hand in hand. The company claims it's three times faster than Google Chrome, and it's available on a wide range of platforms - Windows, Mac, Linux, Android, and iOS. With its recent influx of users, it'll be exciting to see what's next for the browser.
