Sr. Software Engineer, Reliability (Agents of Webapp)
Remote, United States
About the Team
The Agents of Webapp is a Site Reliability Engineering (SRE) team managing Slack’s webserving infrastructure and dedicated to making Slack reliable. We continuously seek to improve the visibility, speed, and safety of Slack’s “webapp” runtime: components at the center of Slack’s distributed application architecture.
We are a growing and changing team, welcoming new perspectives and strategies to address evolving challenges to reliability. We collaborate with many engineering teams at Slack to continuously improve a shared runtime for the webapp: the infrastructure which enables continuous deployment of application code to meet the needs and expectations of millions of Slack users.
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?
What you will be doing
- You will directly support multiple components of Slack’s webserving infrastructure, including Apache, HHVM, Squid, Memcache, Docker, Kubernetes and AWS services.

- You will help develop new deployment mechanisms for our webapp infrastructure, such as: canary, A/B, blue/green, red-line and other deployment patterns
- You will lead large engineering projects, from start to finish, where the scope is mostly understood
- You will define SLA/SLOs for the Slack webapp, manage code deployments, fixes and software updates, and automate our operational processes
- You will participate in the team’s on-call rotation, assist with triaging, and addressing production issues.
- You will review code and get your code reviewed; mentor and be mentored by other engineers. Teamwork is what makes the dream work.
What you should have
- Curiosity about how things work and love to share that knowledge with others
- A positive approach that embraces standard methodologies for software management and reliability, including unit testing, code review, design documentation, debugging, and troubleshooting.
- A passion for reliability, scaling patterns, up-time, and availability.
- A demonstrable history of thriving within a software development team, even if your roles have included traditional operations and/or infrastructure management duties.

- Bachelor’s degree in Computer Science, Engineering or related field, or equivalent training or work experience
- Experience developing and managing modern public cloud infrastructure, especially AWS
Experience Bonus Points:
- as a Site Reliability Engineer (SRE), or as a platform or infrastructure engineer building and managing reliability mechanisms on distributed infrastructure
- deploying, operating and debugging software on Linux at scale
- hands-on, managing full-stack infrastructure, i.e. networking, storage, virtualization and/or host hardware, configuration management and packaging
- using deployment automation/configuration management, such as Chef, Puppet, Ansible or Salt
- with Incident Response programs and processes; including triaging and resolving production incidents at an organization with challenging SLAs and customer expectations
