• We handle about 600k requests per second, summing up the entire day gets us at about 6 billion API requests served per day.

  About the Team
  
  WebApp Infra (WIN) pillar provides the tools to make it possible for hundreds of developers to develop in a multi million line codebase with safety and productivity at the forefront. WIN handles maintenance and upgrades of the Hack programming language, static analysis tooling, widely used libraries in the codebase, asynchronous job queue, as well as tuning and debugging the HHVM runtime and other services it depends on. With four sub-teams : Language, Runtime, Reliability aka WIRE and asynchronous services (AServ), webapp infra team supports the middle layers of the stack above the AWS instances and below the product code. This role is open for the Runtime sub-team.
  
  The WebApp Infra Runtime team is a small team making a large impact. We are responsible for Slack's deployment of HHVM, the virtual machine that runs the Hack programming language that Slack's Webapp backend is written in. We work with product teams to build Hack client libraries and C++ extensions to add more capabilities to WebApp. We fix bugs in HHVM and improve performance across the whole platform. Small improvements can make a big difference: every request that Slack's backend serves runs on systems we support.
  
  We rapidly iterate and work closely with other teams in engineering to ensure we build resilient systems that can scale. We have a strong commitment to quality and understand that simplicity and reliability should be primary aspects of the systems that we build. We are ambitious, independent, and pragmatic.
  -What you will be doing:
  • Collaborate with peers across Engineering to triage bugs and troubleshoot complex production issues across the stack, especially with respect to performance, memory, and stability
  • Write, review, or provide feedback on a technical design proposal
  • Maintain client libraries that allow backend engineers to access all the capabilities of the WebApp platform
  • Test out a patch or new build of HHVM

    • Experience with Linux, including common debugging and profiling tools.
    • Experience building large scale systems professionally for 7-10 years and can point to things you've worked on.
    • Experience improving performance and reliability of a complex system. You enjoy finding opportunities for performance and memory improvements through extensive profiling.
    • Experience with Software-as-a-Service (SaaS). You have deployed plenty of code to live production environments, and understand what it takes to do so safely but efficiently.
    • Can jump into situations with few guardrails and make things better.
    • Write code that can be easily understood by others with an eye towards clarity and maintainability.
    • Are a very strong communicator. You're excited to explain complex technical concepts and share your knowledge with different audiences.
    • Are comfortable leading cross-functional projects and setting a vision for systems architecture.
    • Are curious how things work and when things break you are eager and able to help fix them.
    • Are comfortable mentoring and coaching engineers and sharing feedback.Bonus Points:
      • Have experience working in large C++ codebases.
