Staff Site Reliability Engineer

About Us

Bluesky's mission is to transition the social web from platforms to protocols. We're building a federated social network called AT Protocol where users have more power. Our small team has decades of combined experience building distributed applications.

About the Role

We're looking for a Staff Site Reliability Engineer to help design, implement, and operate the infrastructure that powers Bluesky and atproto. This is a hands-on role for someone who has operated high-scale production systems, understands how distributed systems fail, and wants to build the operational foundation for an open social network.

Key Responsibilities

• You'll work across bare-metal systems, cloud services, data infrastructure, observability, incident response, capacity planning, and reliability engineering for systems serving millions of users.
• Own reliability, availability, and operational excellence for our production systems, including observability, incident response, deployment, and rollback systems
• Improve production readiness for services, migrations, and infrastructure changes
• Develop software that pushes the state of the art in performance, automation, observability, and other areas
• Scale systems running on dense, latest-generation, bare-metal servers in our own colocation facilities
• Reduce toil through automation, tooling, and thoughtful engineering practices
• Partner with engineers across all our teams to help design services with strong operational characteristics
• Lead incident reviews and turn contributing factors into concrete engineering improvements as we practice continuous improvement
• Perform capacity planning and cost management across compute, storage, database, and networking workloads
• Manage various vendor relationships to ensure we can provide high quality services at a reasonable TCO
• Mentor engineers on reliability, operability, debugging, and distributed systems practices and help define a culture of operational excellence across the org

You might be a good fit if you

• Have +10 years experience operating high-scale production systems, including bare metal
• Have strong fundamentals in Linux, networking, storage, databases, and distributed systems
• Have built and operated high-scale systems where correctness, latency, throughput, and availability were critical
• Can write production-quality software in Go
• Are comfortable debugging across application code, operating systems, databases, networks, and hardware
• Have experience with observability systems, alert design, incident response, capacity planning, kubernetes, and production automation
• Like working on very small, fast-moving teams at a startup
• Have read the AT Protocol docs, feel aligned with the mission, and want to contribute!
