Role Description

Are you passionate about automation, DevOps, public cloud services, Kubernetes, and observability? As a site reliability engineer at Legion, you will be responsible for building the tools, infrastructure, and services to create a secure, highly scalable, and cost-effective AWS/Kubernetes-based cloud platform.

• This role involves participation in on-call rotation.
• Build and operate internal AI agents that reduce SRE toil — incident triage, runbook execution, alert enrichment, capacity and cost analysis — and own their guardrails, rollback, and reliability.
• Own the platform that lets other engineers build agents safely: sandboxed execution, scoped credentials, tool/MCP integrations, cost controls, and agent observability.

• Bachelors or Masters degree in Computer Science/Engineering or related field.

Other Qualifications
