Job Description

What You'll Do:

• Operate and improve our multi-account AWS environment running on Amazon EKS, deployed via ArgoCD and Helm
  
• Build and maintain infrastructure as code with Terraform / Terragrunt — everything goes through code review
  
• Support product teams' delivery pipelines: CI/CD design, build optimization, deployment reliability across GitLab and GitHub
  
• Drive infrastructure migration and improvement projects from design through rollout, with clear documentation and audit-ready evidence
  
• Bring hands-on AI expertise to the team, introducing agent-based automation and AI-driven cost/anomaly analysis practices, and mentoring teammates on effective AI-assisted workflows
  
• Monitor, troubleshoot, and tune production systems using Datadog
  
• Participate in the team's on-call rotation and contribute to incident response and post-incident improvements
  
• Identify toil and eliminate it through automation

Qualification

What We're Looking For:
Core requirements:

• Minimum 7 years of professional experience in DevOps, Site Reliability Engineering, or Platform Engineering roles
  
• Demonstrated, hands-on expertise in Kubernetes administration and operations; production experience with Amazon EKS strongly preferred
  
• Strong command of Infrastructure-as-Code practices using Terraform (experience with Terragrunt is a plus), with a track record of managing infrastructure exclusively through code and automated pipelines
  
• Practical, hands-on experience with AI-assisted developer tooling (e.g., Claude Code, GitHub Copilot, or equivalent), including demonstrated success driving adoption of such tools within a team
  
• Solid working knowledge of CI/CD practices and tooling, with experience in GitLab CI and/or GitHub Actions
  
• Proven ability to troubleshoot complex, multi-layered issues, with demonstrated depth in root-cause analysis across the application, container, node, and network layers
  
• Strong sense of ownership and accountability, with the ability to work independently, proactively communicate progress to stakeholders, and produce clear documentation of work delivered
  
• Hands-on experience with GitOps methodologies, particularly using ArgoCD

Strongly preferred:

• Karpenter or cluster autoscaling tuning experience
  
• FinOps / cloud cost optimization experience
  
• Observability tooling beyond dashboards (Datadog APM, log pipelines, custom monitors)
  
• Experience with API gateways and edge stacks (Nginx, APISIX, Cloudflare, or similar) as well as edge security components such as WAF

Certification required: Kubernetes and/or AWS certification, with AWS Certified Solutions Architect – Professional, DevOps Engineer – Professional, or Specialty level preferred
