Sr. DevOps Engineer II (Remote Eligible in Bulgaria)

Responsibilities

• Own and evolve the edge proxy platform by maintaining, upgrading, and extending a high-performance reverse proxy — including maintaining the proxy binary and its configuration tooling, writing Go and Python automation, managing the full container image lifecycle on hardened Linux base images, and working across the broader edge layer, including CDN, WAF, and traffic management capabilities.
• Build and maintain cloud infrastructure as code by designing and implementing Terraform/Terragrunt modules and live environment configurations managing EKS clusters, load balancers, IAM roles, VPC networking, ECR registries, and supporting AWS services across multiple regions including GovCloud.
• Operate Kubernetes clusters at scale by managing multi-region, multi-cluster EKS deployments via FluxCD GitOps workflows and Helm charts, including node AMI rotation, add-on lifecycle management, and horizontal pod autoscaling.
• Build and own CI/CD pipelines by designing, maintaining, and improving shared GitLab CI/CD pipeline templates used across all team repositories, and by building and operating alternative pipeline workflows for isolated government cloud environments.
• Automate operational toil by building and maintaining tooling for tasks such as container image patching, EKS AMI rotation, air-gapped ECR image sync to GovCloud, and automated merge request creation for monthly version-bump patching cycles.
• Manage observability and on-call responsibilities by provisioning and maintaining Datadog SLOs, monitors, and dashboards via Terraform, and by participating in the team's on-call rotation responding to edge proxy incidents across production and GovCloud environments.
• Support FedRAMP/GovCloud operations by operating the GovCloud environment with its unique constraints — air-gapped image distribution, infrastructure automation in isolated networks, and alert management with compliance-aware data handling.
• Evaluate and adopt internal developer tooling by researching, prototyping, and driving the adoption of internal tools that improve engineering productivity across the company — including developer portals, platform self-service capabilities, and other tooling that raises the bar for the developer experience at Smartsheet.
• Mentor and collaborate with peers across the team through code reviews, architecture discussions, and runbook authorship, fostering a culture of engineering excellence and operational rigour.
