About You
You may come from SRE, DevOps, platform engineering, or operations backgrounds. What matters is hands-on experience running production systems, managing incidents, creating runbooks, and automating repetitive work. The focus is on:
- Identifying root causes and systemic issues
- Reducing manual toil through automation
- Maintaining reliability by applying SRE principles and using data-driven metrics (slis/slos)
You understand that reliability is about balance, not perfection, and can make data-driven trade-offs between stability and delivery. You are curious, collaborative, and take shared responsibility for system reliability.
