Senior Staff Software Engineer, Infrastructure

About Us

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

As a Software Engineer, Infrastructure at the Browser Company, you’ll create the systems, tools and infrastructure that that unlock rich product experiences in Dia as we scale. You'll build the architecture that powers Dia's AI capabilities, enabling our team to prototype and ship innovative browser automation and AI-driven features rapidly. You’ll also have the opportunity to work on different products and surfaces areas across the company — we value mobility and folks getting to work on the problems they’re most interested in.

Overall You Will

• Scope and spearhead technical projects across client, browser, and OS layers.
• Support the infrastructure and architecture that enable Dia’s core features—primarily working in Swift, but also flexing into C++ and Chromium—to help the team build and deliver new capabilities.
• Design APIs that abstract away complexity and empower engineers to iterate quickly, collaborating closely with engineering teams across the company in the process.
• Invest in observability, tooling, stability, and performance—continually improving our AI product infrastructure, deployment systems, release process, and feature flag systems.
• Contribute directly to the Chromium codebase by participating in engineering rotations, responding to incidents, and supporting major upgrades, while sharing knowledge with the broader team.
• Take ownership of key infrastructure areas, serving as the primary point of contact for product engineers on questions of performance and reliability.
• Regularly participate in code reviews, architectural discussions, and efforts to improve engineering best practices.

Qualifications

• 10+ years of experience leading critical projects or initiatives in client-side or C++ infrastructure environments, with deep hands-on C++ development experience.
• Experience with Chromium is a plus—we’re especially interested in folks who are excited to dive in and learn the Chromium codebase.
• You've worked on large, complex codebases and understand how to improve systems to make them easier to understand, debug, and maintain.
• You're passionate about building tools and systems that make other engineers more productive and strive to make them elegant and maintainable.
• You’re pragmatic, motivated by nebulous problems, and excited to work in a startup environment with quick product validation cycles.

Location & Time Zone Requirements

• We’re primarily focused on hiring in North American time zones.
• We require that folks have 4+ hours of overlap time with team members in Eastern Time Zone.

Compensation and Benefits

• With our flexible compensation model, employees have the ability to choose the cash-to-equity ratio that best suits their individual needs.
