Join a team that delivers modern, secure, cloud-native solutions on high-impact government programs.

Position Overview

We are seeking a Senior DevSecOps Engineer to secure, automate, and scale cloud-native data platforms on AWS. This role centers on hardening and operating Amazon EMR (Spark) and OpenSearch workloads, building secure CI/CD pipelines, managing infrastructure-as-code, and embedding security throughout the delivery lifecycle. You'll work in a JVM-based codebase (Java/Kotlin/Scala), so a solid software-engineering foundation is required — but the emphasis is on cloud, security, and platform reliability. This role supports a federal program and requires the ability to obtain and maintain a Public Trust clearance.
