Qualifications

5+ years securing cloud-native platforms with a focus on distributed systems and multi-tenancy.

Bachelor’s or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent.

Strong hands-on experience with AWS (IAM, VPC/networking, logging/monitoring, …) and Kubernetes/container security.

Proficiency with Terraform and Helm.

Experience building or operating runtime detections for containers/functions.

Strong technical background in backend systems, cloud infrastructure, or AI tooling

Clear written and verbal communication; ability to translate pricing/business rules into robust systems.

Preferred Experience

Knative or similar serverless-on-K8s frameworks.

Container hardening and sandboxing.

Policy-as-code and admission policy design at scale.
