Sr. Software Engineer - UI

About Brave

Brave is on a mission to protect the human right to privacy online. We’ve built a free web browser that blocks creepy ads and trackers by default, a private search engine with a  truly independent index, a private ad network (opt-in!) that directly rewards you for your attention, and a browser-native AI integration focused on keeping private data private. And we’re just getting started. Already 110 million people have switched to Brave for a faster, more private web. Millions more switch every month.

The internet is a sea of ads, hackers, and echo chambers. Big Tech makes huge profits off our data, and tells us what’s true and what’s not. Brave is fighting back. Join us!

The Browser AI team are building core browser features, and exploring new ideas about how the personal nature of the browser can help create the best AI experience for research  and creative tasks. Brave allows the user to attach tabs, history, bookmarks and files to AI conversations. Brave also allows the user to experiment with AI joining in with its own web browsing. We’re looking for a new team member capable of iterating these ideas and creating beautiful user experiences for these features. UI engineers will often work with other engineers to create the end-to-end features, or develop the skills necessary to implement the entire feature themselves.

Brave has an exciting UI engineering culture. We share knowledge and patterns across both teams and disciplines, overlapping closely with designers. We work with internal design systems, multiple UI frameworks, and make effective decisions on these features as a team.

This role is at an exciting intersection between web UI, web browser internals, and AI possibilities.

Brave is a start-up, and we have the ability to change plans quickly in response to new information or circumstances. This means that new needs can emerge on short notice, and projects are often re-mixed and adjusted in response to new input. Successful applicants will have the opportunity to influence those choices and other areas of the team.

Many engineers in this role at Brave start from a frontend or full-stack background and grow into browser-level C++ feature work over time.

Responsibilities will include:

• Implementing browser-integrated Web UI (e.g. AI conversations, browser settings, new tab page) using Typescript, JavaScript, HTML and CSS with React as well as other frameworks such as Web Components, Svelte and Lit

• Working with our product development team to collaborate on designs and specs and bring them to life on Brave’s desktop and mobile browsers

• Integrating with custom browser APIs using Chromium’s communications frameworks.

• Helping to customize the native UI provided by Chromium to add new product features and modify existing features. These UI elements include toolbars, modals, buttons, and more

Required experience:

• Strong skills building complex web apps with state management

• Deep knowledge of a Javascript UI framework such as React, Svelte, Vue, or native Web Components

• Proven expertise with CSS for building UI

• Commitment to various UI accessibility and localization techniques

• Understanding of performance impact and how both to measure and make improvements

Preferred experience:

• Proficiency with a class-based object-oriented language, such as Java, C#, PHP, Objective-C or C++. C++ expertise or experience with Chromium is  not required, but a willingness to learn and the ability to grasp the concepts quickly will be expected.

• Working with and graspine large code repositories

• AI coding tools

• Knowledge of how LLMs and their associated tools and APIs work

Working at Brave
