This role involves shipping code for services that monitor and manage the platform, including auto-remediation, capacity forecasters, and oncall tooling, as well as capacity planning, load testing, and autoscaling.
Responsibilities
- Join the oncall rotation within 30 days.

- Define the initial set of SLOs for the call-completion path.
- Establish error budgets and SLO-based alerting in Chronosphere/Prometheus for key services within 60 days.
- Conduct the first comprehensive load test against provider rate limits and per-org concurrency.
- Tune autoscaling for wscaler and workerpool-cron-scaler.
- Ship a platform service (capacity forecaster, auto-remediation, or oncall tooling) in Go or TypeScript within 90 days.
- Own the postmortem process.
- Drive measurable improvements in p99 call completion or MTTR.
Requirements
- Experience running incident command and postmortem discipline at scale on an oncall rotation.
- Experience operating SLOs and error budgets using tools like Chronosphere, Prometheus, Grafana, or Datadog.
- Experience with capacity planning and load testing for production systems with live users.
- Proficiency in Kubernetes production operations, including pod crash diagnosis, HPA/VPA tuning, PodDisruptionBudgets, and graceful shutdown.
- Knowledge of backpressure and autoscaling patterns such as KEDA and custom metrics scaling.
