Android Performance Engineer

Slack has a positive, diverse, and supportive culture—we look for people who are curious, inventive, and work to be a little better every single day. In our work together we aim to be smart, humble, hardworking and, above all, collaborative. If this sounds like a good fit for you, why not say hello?

Slack is looking for a Software Engineer with experience in high-performant Android apps that get the job done. We love engineers who believe performance is a key feature of every product we build, and don't mind digging into some stack traces to make things faster. We love performance optimization, improving maintainability, and iterating on best-practices with the rest of the Android teams. Our team is cultivating a culture of performance at Slack.

Our work depends on working closely with other teams at Slack, so communication and collaboration skills are a must. This is an opportunity to work on a small team that directly affects how Slack’s desktop web client is built.

This position is remote and reports to one of our engineering managers.

What we are looking for:

  • You have experience with the Android Studio Profiler and other tools that help measure and investigate system performance to make informed decisions about how to optimize the app.
  • Experience developing highly performant Java code and view layouts and the ability to diagnose performance bottlenecks
  • A familiarity with the Android tool ecosystem for development, testing, debugging, and performance benchmarking
  • An excellent understanding of best practices for concurrency and threading
  • Someone who can find issues and improve code performance in the “under hood areas” of the app as well as in the UI / view logic.
  • Diving into a new system to understand mysterious behavior excites you, and the phrase “things are slow, but only sometimes” sounds like the start of a great adventure
  • You write understandable, testable code with an eye towards maintainability and scalability.
  • You are comfortable with SQL and making sense of data.
  • You are a strong communicator and are equally comfortable talking with your immediate team, other frontend engineers, or even backend infrastructure engineers.
  • You are ready to learn, but just as excited to teach.
  • You understand that the perfect solution is informed by the people who will be building on your work, rather than being purely dependent on technical merits. Empathy is a feature.
  • You have a bachelor's degree in Computer Science, Engineering or a related field, or equivalent training, fellowship, or work experience.
