Office Tech-Flexible

Developer Workspaces runs the computers Slack engineers write code on - and more and more, the ones AI agents write code on. Every week, hundreds of engineers build and test Slack in the remote development environments we run on AWS and Kubernetes. Now we're building the next layer: fast, isolated sandboxes where coding agents can run a dev toolchain, open pull requests, and shut down when they're done.

If most of Slack's code is going to be written by agents, it'll be written on infrastructure this team owns.

We're a small team with a lot of surface area. We're strong on backend engineering, and we need more depth in infrastructure and operations. That's this role. You'll own production systems early, carry the pager, and help decide how agents run safely at Slack.

What You'll Actually Be Doing

* Scale our AI sandbox fleet into something the whole company depends on - capacity planning, safe rollouts, image builds, and the alerts that tell us when it's breaking. * Harden the isolation between agents, sandboxes and the rest of Slack: network separation, egress controls, secrets handling, and patching. * Run and improve the remote dev environments our engineers use every day, from Terraform and machine images to the automation that pauses idle environments so they don't burn money. * Build observability we can make decisions with - SLOs, dashboards, and logs that land where we can find them. * Join our weekly on-call rotation once you've ramped up. Most pages are low urgency. When something does break, we fix it and then automate the fix. * Use AI agents heavily in your own work. You're building the platform they run on, so you should know what they need.
