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.
