We are looking for a Software Development Engineer to join the
EKS KCP Scalability team and work on some of the hardest distributed systems problems at Amazon. You will design, build, and operate systems that directly determine whether
EKS customers — from startups to the largest AI/ML workloads on the planet — experience a reliable, performant control plane.
This is not a role where you implement features in isolation. You will work across the full stack: from the
Kubernetes API server process and upstream community engagement, through autoscaling services that right-size control planes in real time, to the
SLA measurement pipelines that hold us accountable to our customers. You will own systems end-to-end — from design through production operations — and your work will be measured by customer outcomes, not lines of code.
Key job responsibilities
You will build and operate the Vertical Auto-Scaling Service (
VAS) and its next-generation successor (
VAS 2.0), which dynamically right-sizes
EKS control planes by evaluating CPU/memory utilization, etcd throttle rates, node-count thresholds, and network utilization simultaneously. You will work on the
SLA measurement pipeline (MinutelySLA → DailySLA → MonthlySLA) that enforces
EKS's uptime commitments, investigating breaching clusters weekly and building automation to detect and mitigate degradation before customers notice.
You will contribute to the control plane architecture for
EKS Ultraclusters, defining how the
API server, etcd, and associated components scale to support 100,000-node clusters running generative AI workloads. You will maintain and extend version release qualification scale tests that gate every new
Kubernetes version before it reaches customers. You will engage with the upstream
Kubernetes community — driving KEPs that work backwards from
EKS customer requirements around performance, scale, and resiliency.
Depending on your interests and the team's priorities, you may also work on workload identity systems (IRSA,
EKS Pod Identity), Cluster Access Management,
EC2 capacity management and grey failure detection, or Large-Scale Event response and weight shifting.
About the team
The
EKS KCP Scalability organization owns the performance, availability, and autoscaling of the
Kubernetes control plane powering Amazon
EKS — from small development clusters to 100,000-node Ultraclusters running generative AI workloads. We ensure every
EKS cluster operates within its contracted
SLA and delivers predictable, high-performance behavior at any scale.
Our charter spans three domains: Performance , Availability + Autoscaling , and Auth. We operate at the intersection of distributed systems,
Kubernetes internals, and
AWS infrastructure — building systems that scale to hundreds of thousands of clusters globally.
