- Knowledge of scheduling concepts like quota enforcement, pre-emption, and scaling strategies.
- Exposure to reliability practices including SLOs, alarms, and post-incident reviews.
- Experience with AI infrastructure and workloads (ML training, inference, or HPC).
- Wondering if you're a good fit?
- You love defining long-term architecture for systems at global scale.
- You're curious about orchestration beyond SUNK and how to evolve it for next-generation AI.
