Responsibilities
- Be a first responder in the event of cluster outages or issues. Triage and resolve urgent issues as they arise
- Ensure a high degree of cluster uptime (measured in multiple nines), and define + track SLAs to quantify reliability
- Diagnose systemic/recurring patterns of problems, and engineer precision solutions to them in collaboration with engineering teams
- Develop robust metrics and observability for cluster health and use those metrics to inform your work. Build out custom observability mechanisms when off-the-shelf ones won't do
- Help software and research teams design policies around fair cluster usage, and help develop enforcement mechanisms for said policies
- Assist in forecasting cluster growth, and help select appropriate scale-up strategies. Help optimize operations across dimensions of cost and usability
Skills
- 5+ years of experience in SRE or DevOps roles, preferably working as a senior engineer or tech lead
