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.

About the Role

At The Browser Company, we've taken a unique approach to building our Swift/Chromium web browsers for 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 and Dia using Swift. A small team of language compiler and systems engineers have implemented the protocol that allows us to run our Swift code across MacOS, Windows, iOS and Android. We’re part of the Swift core team and work closely with Apple, supporting Windows and Android. You can read more about our open source work on our company Github and our Speaking in Swift blog.

As a Compiler Engineer at The Browser Company, you'll advance Windows support for Swift and build features that benefit both our internal projects and the broader Swift community. Your work will shape how we build browsers and cross-platform applications, with Swift at the core of our stack. You'll collaborate with the open-source community, Apple, and other companies using Swift while tackling deep technical challenges in language and compiler design.

Overall you will

• Enhance Compiler Performance: Investigate and address performance bottlenecks, focusing on areas like memory allocation, PGO/LTO/BOLT, and hot function optimizations. Collaborate with cross-functional teams to improve build times and developer productivity.

• Platform Support: Maintain and expand support for multiple operating systems, including Windows and Android. This includes enabling CI testing, debugging tools, and profiling capabilities to ensure robust toolchain performance. Maintain and improve support for multiple architectures including X86_64 and ARM64 across different Operating Systems. Be involved in emerging architecture support as well (e.g. RISCV).

• Toolchain Development: Build and maintain custom toolchains on macOS and Windows, ensuring seamless integration with tools like Xcode and VSCode. Develop deployment solutions for alternative toolchains to enhance developer workflows. Work to support new platforms for cross-compilation and improve existing ones across the compilation pipeline.

• Cross-Language Interoperability: Drive innovations in Swift and C/C++, Java/Kotlin interoperability, enabling seamless integration for Windows and Android application development. Improve Swift's interoperability with C and C++ codebases to improve developer experiences with multi-lingual codebases.

• Open Source by Default: Nearly all of your work lands upstream in LLVM, Swift, and related projects. Your contributions are visible, impactful, and benefit the wider developer community.
