Posted on Sunday, June 18, 2023
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 question 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
Building a web browser is an extraordinary technical and product undertaking. As a Software Engineer on the Performance Team, you will solve unique architectural and systems challenges to help us achieve our goal of making Arc the fastest browser on the market.
In this role, you’ll come up with creative ways to diagnose common complaints and implement creative ways to improve performance for Arc’s hundreds of thousands of members. Performance engineers here will not be limited to one aspect of the application but will have the agency to understand and prioritize work across our technical stack.

Overall you will...

  • Improve our systems and architecture so that Arc can be more performant in a variety of areas - RAM usage, CPU usage, battery life, interaction speed, and loading performance
  • Collaborate with our Membership, Data, and Engineering teams to understand and triage user-facing performance issues
  • Implement tooling and testing to measure various aspects of performance so that we can make data-informed improvements over time
  • Improve our performance tooling and testing systems so that we can better detect and debug performance issues in production
  • Dive into a large codebase (spanning Swift → Chromium) and understand how we can improve Arc’s performance within a certain part of the technical stack (eg. Swift layer, Chromium rendering path, etc)

Within 1 month you will...

  • Get onboarded onto the team and codebase with an onboarding buddy
  • Receive a number of onboarding presentation on how we give each other feedback, the phases a startup goes through, our technical strategy, and more
  • Get familiar with Swift, Chromium, and our development environment
  • Get familiar with our performance tooling and data
  • Have shipped at least one performance improvement in a part of our technical stack
  • Have shipped at least one improvement to our performance tooling
  • Have pair programmed with others on our engineering team

Within 3 months you will...

  • Be the point of contact for bugs, regressions, and performance work on a few performance-related work-streams
  • Have identified and shipped a few projects to improve performance, our ability to debug issues, and better track it with data.
  • Have instituted process or tooling for us to prevent some causes of performance issues
  • Have developed in-depth knowledge on classes of performance issues within a certain aspect of performance and/or part of the technical stack
  • Be involved in weekly engineering discussions about our architecture, how we do code review, code style, and more
  • Be involved and help drive discussions around performance and best practices for writing performant product code with other engineers
  • Have started pairing with other engineers in debugging performance issues in code from other teams

Within 6 months you will...

  • Be interview trained and interviewing candidates for roles at the Browser Company, especially performance-related ones
  • Have a major part in defining Browser Company’s technical roadmap as it relates to performance in Arc
  • Help define our strategy for tooling and data as it relates to performance
  • Have identified and shipped significant architectural changes to mitigate classes of performance issues in Arc
  • Actively supporting and mentoring other engineers in identifying performance issues in their code and suggesting tactics for how to resolve them


  • You have experience working on performance in at least one of the following types of applications: iOS or macOS (written in Swift or Objective-C), Chromium-based applications, Web browser (eg. Chrome, Edge, Safari, Firefox, etc.), C++, or Windows
  • Experience with best practices, tools, and techniques for analyzing, debugging, and improving performance in an application
  • You have experience tech leading critical projects or initiatives within your team and organization
  • You’re able to identify and debug issues and make improvements on large, complex codebases that you might not be completely familiar with
  • You’re motivated by nebulous problems and can bring structure and clarity to them
  • You're pragmatic and can see the bigger picture; you're able to reason about prioritization and scope
  • You bias to action. We like learning as quickly as possible, so we embrace failing fast to refine our code, systems, and processes rapidly.
  • You have at least 4 hours of overlap time with team members located in Eastern Standard Time
