Job summary

Heartflow seeks a Senior Platform Engineer to lead the Compute Migration effort, moving AWS Lambda and ECS workloads to a Kubernetes platform on AWS EKS, focusing on performance, cost, reliability, and security.

You will define roadmaps, build automated tooling with Terraform, Terragrunt, and Helm, and partner with engineering teams to deliver reusable CI/CD workflows, observability, and guardrails across the platform.

Qualifications

• 8+ years of experience in Platform, Infrastructure, or DevOps Engineering roles, with significant time spent on large-scale compute migrations.
• Expert-level proficiency in Kubernetes (design, deployment, operations, networking, security, and scaling).
• Deep, hands-on experience with AWS compute services, particularly AWS Lambda and ECS/Fargate, and a clear understanding of their operational models and scaling behaviors.
• Proven experience migrating production workloads from traditional cloud compute (VMs, Lambdas, ECS) to Kubernetes.
• Strong background in Infrastructure as Code (IaC), specifically Terraform.
• Proficiency with containerization technologies (Docker) and modern CI/CD practices.
• Excellent communication, documentation, and technical leadership skills, with the ability to influence technical decisions across multiple teams.

Responsibilities

• Define the technical roadmap, migration patterns, and reference architectures for moving Lambda functions and ECS services to Kubernetes on AWS EKS.
• Develop robust, scalable, and automated solutions for running event-driven, serverless-like workflows on Kubernetes.
• Use Terraform/Terragrunt and Helm to build and manage the underlying Kubernetes infrastructure, networking, and deployment tooling.
• Partner with engineering teams to understand workload requirements and develop standardized migration tools and CI/CD pipelines.
• Benchmark migrated services, optimize resource requests/limits, and implement observability solutions to maintain or improve SLOs.
• Establish guardrails and documentation for running event-based compute on Kubernetes.
