About the role

Key responsibilities & impact
  • Lead software engineering teams providing infrastructure-as-code to manage cloud infrastructure.
  • Establish governance and mechanisms for application development teams to self-service infrastructure provisioning, while providing for best practices and controls.
  • Provide documentation, training, and support to ensure feature dev teams are leveraging self-service capabilities.
  • Hire experienced site reliability staff, and a line manager to grow and oversee the SRE team.
  • Professionalize incident management. Define and document incident processes and practices for your SRE team and for the application feature teams.
  • Drive incident professionalism across the engineering organization through training and process adoption.
  • Establish design-before-build discipline. Facilitate lightweight design documents, architectural decision records, and working group reviews.

Requirements

What you’ll need
  • Demonstrated experience leading teams operating SaaS service infrastructure.
  • Deep hands-on experience deploying and operating production infrastructure on public cloud platforms (AWS strongly preferred; Azure and GCP familiarity a plus).
  • Strong command of Infrastructure as Code, including Terraform; experience with Crossplane and GitOps patterns strongly preferred.
  • Experience managing production Kubernetes environments at scale.
  • Solid understanding of security best practices including zero trust architecture, secrets management, identity and access management, and software supply chain security.
  • Experience building and operating self-service infrastructure platforms that enable application development teams, while balancing self-service and developer productivity with maintainability and security.
  • Experience leading or building SRE functions, including incident management processes, on-call programs, SLO/SLA definition, and operational runbooks.
  • Deep hands-on experience with observability: application performance management, logs and traces, and golden signals and service-specific metrics.
  • Expert in leading infrastructure teams to translate business and product requirements into technical requirements and engineering deliverables.
  • Proven ability to hire, develop, and retain high-performing engineers and engineering managers in remote or distributed environments.
