the browser company

Hi, we're The Browser Company 👋 and we're building a better way to use the internet.Browsers are unique in that they are one of the only pieces of software that you share with your parents as well as your kids. Which makes sense, they're our doorway to the most important things — through them we socialize with loved ones, work on our passion projects, and explore our curiosities. But on their own, they don’t actually do a whole lot, they’re kind of just there. They don’t help us organize our messy lives or make it easier to compose our ideas. We believe that the browser could do so much more — it can empower and support the amazing things we do on the internet. That’s why we’re building one: a browser that can help us grow, create, and stay curious.To accomplish this lofty task, we’re building a diverse team of people from different backgrounds and experiences. This isn’t optional, it’s crucial to our mission, as we need a wide range of perspectives to challenge our assumptions and shape our browser through a bold, creative lens. With that in mind, we especially encourage women, people of color, and others from historically marginalized groups to apply. Browsers know everything about us and what we do everyday, yet they can’t predict our next move, morph themselves to better suit our tasks, or proactively reduce repetitive tasks during your work day. At The Browser Company, we’re changing that by building Dia.

With that in mind, we especially encourage women, people of color, and others from historically marginalized groups to apply. The Browser Company has taken a unique approach to building Arc, our Swift/Chromium web browser, on multiple platforms. While most major browsers are written in C++, we decided to avoid challenges around slow iteration speed and memory safety by building Arc using Swift. A small team of language compiler and systems engineers, led by Saleem Abdulrasool, have implemented the protocol that enables us to run our Swift code across MacOS, Windows, iOS and Android. As a Systems Engineer on the Compiler Team, you’ll focus on improving the Swift compiler and toolchain to enable our team to build for Windows. Your work will directly contribute to our efforts to redefine how browsers and cross-platform applications are built, leveraging Swift as a core part of our technology stack. • Spearhead technical projects for existing and new features across the Swift compiler, toolchain, SDK and frameworks for Windows.

Hi, we're The Browser Company 👋 and we're building a better way to use the internet.Browsers are unique in that they are one of the only pieces of software that you share with your parents as well as your kids. Which makes sense, they're our doorway to the most important things — through them we socialize with loved ones, work on our passion projects, and explore our curiosities. But on their own, they don’t actually do a whole lot, they’re kind of just there. They don’t help us organize our messy lives or make it easier to compose our ideas. We believe that the browser could do so much more — it can empower and support the amazing things we do on the internet. That’s why we’re building one: a browser that can help us grow, create, and stay curious.To accomplish this lofty task, we’re building a diverse team of people from different backgrounds and experiences. This isn’t optional, it’s crucial to our mission, as we need a wide range of perspectives to challenge our assumptions and shape our browser through a bold, creative lens. With that in mind, we especially encourage women, people of color, and others from historically marginalized groups to apply.

With that in mind, we especially encourage women, people of color, and others from historically marginalized groups to apply. The Browser Company has taken a unique approach to building Arc, our Swift/Chromium web browser, on multiple platforms. While most major browsers are written in C++, we decided to avoid challenges around slow iteration speed and memory safety by building Arc using Swift. A small team of language compiler and systems engineers, led by Saleem Abdulrasool, have implemented the protocol that enables us to run our Swift code across MacOS, Windows, iOS and Android. As a Software Engineer, Build Systems on the Compiler Team, you’ll focus on improving the Swift compiler and toolchain to enable our team to build for Windows. Your work will directly contribute to our efforts to redefine how browsers and cross-platform applications are built, leveraging Swift as a core part of our technology stack. • Spearhead technical projects for existing and new features across the Swift compiler, toolchain, SDK and frameworks for Windows.

Hi, we're The Browser Company 👋 and we're building a better way to use the internet.Browsers are unique in that they are one of the only pieces of software that you share with your parents as well as your kids. Which makes sense, they're our doorway to the most important things — through them we socialize with loved ones, work on our passion projects, and explore our curiosities. But on their own, they don’t actually do a whole lot, they’re kind of just there. They don’t help us organize our messy lives or make it easier to compose our ideas. We believe that the browser could do so much more — it can empower and support the amazing things we do on the internet. That’s why we’re building one: a browser that can help us grow, create, and stay curious.To accomplish this lofty task, we’re building a diverse team of people from different backgrounds and experiences. This isn’t optional, it’s crucial to our mission, as we need a wide range of perspectives to challenge our assumptions and shape our browser through a bold, creative lens. With that in mind, we especially encourage women, people of color, and others from historically marginalized groups to apply. As a Software Engineer on the Developer Experience Team, you’ll build the tools and systems that enables your teammates to be happier and more productive. From creating ephemeral Mac CI runners to improving debugging systems for our bespoke Swift on Windows environment (read more about our Swift interoperability work on our blog), you’ll remove friction points that allow our engineers to make weekly updates to Arc and Dia for millions of users. • Proactively identify inefficiencies across the build, test, and release loops and spearhead projects to make them better.
