About the role

Senior Platform Engineer focusing on building and migrating to a new AWS foundation, with initial project migrating CDK-based serverless applications to Kubernetes (EKS) and broadening platform responsibilities including SRE and developer experience.

Responsibilities

  • Contribute to migration patterns and reference implementations for moving CDK-based serverless applications to EKS, while supporting cross-account interoperability during the migration window.
  • Translate existing CDK stacks into Terraform/Terragrunt, Helm, service templates, and developer portal integrations.
  • Develop robust, scalable, and automated solutions for running event-driven, serverless-like workflows on Kubernetes, potentially utilizing technologies like KEDA or similar cloud-native tools.
  • Plan data-tier and API cutovers that keep downtime and risk low.
  • Work with application teams to understand workloads, sequence moves, and provide tooling and documentation to migrate with minimal hand-holding.
  • Benchmark migrated services, tune resource requests and limits, and ensure observability and SLOs match or exceed previous performance.
  • Build and maintain cloud foundations: account structure, networking, IAM, and shared services, all as code.
  • Contribute to SRE practices: SLOs, alerting, incident response, capacity and cost management, and on-call rotation as the team matures.
  • Improve developer experience through Harness pipelines, golden paths, and the Cortex service catalog, treating internal engineers as platform customers.
  • Write standards, guardrails, and runbooks for others to follow without asking.
  • Support Linux and Windows systems where the platform requires them, with automation preferred over manual work.

Qualifications

  • Several years of platform, infrastructure, SRE, or DevOps engineering, including at least one migration of production workloads to a new platform or architecture (e.g., Fargate/ECS to Kubernetes or serverless to containers).
  • Strong working knowledge of Kubernetes on AWS (EKS): networking, security, scaling, and day-two operations.
  • Solid AWS experience across compute (Lambda, ECS, EKS), data (RDS), API Gateway, VPC networking, and IAM.
  • Production experience with Terraform, and comfort with Helm.
  • Scripting and automation skills in Bash, Python, or Go.
  • Hands-on experience with CI/CD systems and containers.
  • Clear written and verbal communication, and a track record of influencing technical decisions across teams.
