Software Engineer II, Reliability

Requirements:

• Have experience operating cloud-native production systems and services
• Write production-quality code (e.g. Python, Go, or similar) to automate operations and improve reliability
• Understand common failure modes in distributed systems, such as dependency failures, resource exhaustion, and partial outages
• Have experience working with containerized workloads and platforms (e.g. Kubernetes) in production environments
• Are comfortable participating in on-call rotations and diagnosing straightforward production issues
• Have experience using observability tools and responding to alerts
• Are familiar with SRE concepts such as SLIs, SLOs, and error budgets, and are learning how to apply them in practice
• Have hands-on experience with infrastructure as code or declarative configuration (e.g. Terraform, Kubernetes manifests)
• Can follow incident response processes and contribute meaningfully during outages
• Are comfortable receiving feedback, learning from incidents, and improving your systems over time

Nice to Have:
