Infrastructure Engineer - Test Infrastructure

About the Team

Slack is looking for engineers to design and build solutions and automated processes to improve the performance and insights we gain from our software testing systems.

This is an excellent opportunity for a generalist or an operations engineer who enjoys working on platforms and infrastructure that Slack engineers rely on to build software and execute automated tests to release high-quality products. We work with many different teams and products. One size does not fit all so please bring your bag of tricks.

About the Role

What you will do:

  • Collaborate with engineering teams to build reliable end-to-end test infrastructure, processes, and interfaces for native clients and backend services test suites.
  • Implement tools and technologies like Kubernetes to provision and configure scalable testing frameworks in public clouds.
  • Identify, automate, and teach engineers how to optimize repeated tasks.
  • Participate in the team on-call rotation, triaging and addressing production issues as they arise.

Projects you might work on:

  • Improve monitoring and alerting for pre-production testing systems and workflows.
  • Implement automatic provisioning to meet demands for testing environments.
  • Build a parallel processing framework for distributing load for complex tests.

You might be a good fit if:

  • You are a strong communicator. Explaining complex technical concepts to designers, support, and other engineers is no problem for you.
  • You love mentoring and modeling behaviors for writing unit tests, code review, design documentation, debugging, and troubleshooting.
  • You champion a data-driven approach to iterating on complex problems and your team’s  impact can be proven via metrics.
  • You have curiosity about how things work.



  • Firm grasp of computer science fundamentals: data structures, algorithms, programming languages, distributed systems, and information retrieval.
  • Strong understanding of how the web works: you know HTTP, SSL and TCP/IP and what a good API looks like.
  • Bachelor's degree in Computer Science, Engineering or related field, or equivalent training, fellowship, or work experience.

Would be great to have:

  • Experience in DevOps or Site Reliability for a company experiencing fast-paced growth.
  • Experience using deployment automation/configuration management, especially Chef.
  • Experience with virtualized environments (AWS experience a plus).
  • Prior experience with automation frameworks (Selenium, Cypress, RSpec).
  • An interest in developing infrastructure for testing mobile applications.
