• Design and evolve infrastructure-as-code and automation standards used across the team
• Administer and scale critical database and storage systems at production scale
• Mentor engineers, review designs, and raise the technical rigor bar across the team
• Partner with engineering, product, and other cross-functional teams to embed reliability, scalability, and observability requirements into the development lifecycle
• Evaluate and introduce new tools and platforms to improve reliability and team velocity

• Expertise in version control (Git) and automated build/test systems (Jenkins, Vagrant)
• Expertise in Kubernetes platform experience, on-premise or cloud
• Experience with at least one major cloud infrastructure platform, including architecture-level decisions
• Hands on experience with storage platforms (NetApp, Isilon, object storage) at scale
• Hands on experience in configuration management (Puppet, Ansible)
• Hands-on experience with enterprise-grade x86-based hardware platforms

• Excellent verbal and written communication skills — able to articulate, document and otherwise communicate technical concepts/details to both technical and non-technical audiences
• Practical experience with GitOps infrastructure automation
• Deep experience with multi-platform cloud and on-premise applications at scale, particularly with AWS and/or Alicloud
• Experience migrating bare metal/virtualized applications and infrastructure to containerized cloud deployments
• Experience building web applications and services at scale in Go
• Experience with large-scale systems — performance tuning, replication, failover — as part of an SRE role
• Experience with security hardening of production infrastructure at scale
