iOS Application Infrastructure Engineer

We're looking for people who are passionate about building the foundational components that underpin great iOS applications. iOS Application Infrastructure Engineers enable iOS Product Engineers to build new features quickly, safely, and with confidence.

You've been around for a few Xcode releases and you know how to delight iOS users. As an application infrastructure engineer, you will find yourself looking deeper than the immediate bug or problem in front of you and towards how you can design a system that prevents the issue from happening in the first place. Your code will be the foundation for the core features of the Slack iOS client and you will constantly be thinking of ways to make the app perform better for Slack’s users. Use your extensive knowledge of building and scaling applications to make the Slack experience on iOS be the best it can possibly be.

Slack on iOS is used by millions of people every week - we need engineers who want to make that experience as enjoyable as possible.

Requirements:

  • Bachelor's degree in Computer Science, Engineering or related field, or equivalent training, fellowship, or work experience
  • Strong computer science fundamentals: data structures, algorithms and programming languages
  • An excellent understanding of best practices for networking, concurrency and threading
  • Experience with complex API and library design and implementation, with an emphasis on modularity
  • A disciplined approach to development, testing, documentation and code structure in a highly collaborative team environment
  • A familiarity with the iOS tool ecosystem for development, testing, debugging, and performance benchmarking
  • At least four years of engineering experience, a large portion of which in a team environment
  • Extensive understanding of the Cocoa framework
  • A constant desire to improve, learn more, and leave things better than you found them.

Bonus Points:

  • Experience using Slack and a keen interest in making it better
  • Experience developing with Swift
  • Experience debugging and fixing and app performance issues
  • A passion for building and maintaining great open source projects or otherwise contributing to the iOS community
  • Experience with web development, distributed systems and parallel processing
