- Automate operational tasks and infrastructure management with Python or Go.
- Design scalable, fault-tolerant infrastructure across AWS, GCP, and Azure.
- Work fluently across Kubernetes, Helm, and Terraform.
- Run agents in your daily loop to investigate incidents, draft changes, write runbooks, and scaffold tooling.
- Build agentic setups where humans and digital teammates work as one team.
- Encode recurring infra tasks as internal skills for teammates.
- Lead incident response, post-mortems, and root-cause analyses.
- Own the reliability, performance, and efficiency of WRITER's core services end-to-end.
- Define and uphold SLOs and error budgets.
- Carry the on-call pager and stand behind the outcome metric.
- Balance critical weekly work with 6-12 month platform direction.

- Strong opinions on AI reliability.
- Demonstrated ability to challenge the status quo and identify systemic weaknesses.
- Ability to propose innovative solutions to complex reliability problems.
- Reason from constraints and failure modes.

- Work fluently with monitoring and logging stacks (Prometheus, Grafana, ELK or equivalent).
- Stress the system in safe places.
- Excellent communication, collaboration, and problem-solving skills.
