Software Engineer , Service Network - Slack

About the Service Network team is at the core of what makes Slack work — fast, secure, and reliably — for over 14 million daily active users worldwide. We design and operate the service‑to‑service networking fabric that powers Slack's platform, built on advanced service mesh technologies and intelligent service discovery. Our work enables secure, scalable, and resilient communication across internal services, enforcing strong security boundaries and maintaining high availability for our users.

Slack's infrastructure is constantly evolving to match our fast‑growing business. The roadmap focuses on making infrastructure easier to use for the engineers who build on top of it — delivering capabilities like blue‑green deployments out of the box. We iterate quickly, collaborate closely across engineering, and hold ourselves to a high standard of simplicity and reliability in everything we ship.

• Proficiency in Go, Python, Ruby, C, or C++.
• Experience configuring and operating service mesh at production scale, with a focus on stability, scalability, and performance.
