One Dynamic

One Dynamic is a Service-Disabled Veteran-Owned Small Business (SDVOSB) headquartered in Fairfax, VA, specializing in digital transformation, cloud infrastructure, quality assurance, and enterprise architecture. We serve federal and healthcare organizations as a trusted partner for mission-critical technology initiatives. Join a team that delivers modern, secure, cloud-native solutions on high-impact government programs.

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.

• Strong hands-on experience with AWS services: EC2, S3, IAM, VPC, EKS
• Experience securing and scaling Amazon EMR (Spark) and OpenSearch
• Proven experience managing Kubernetes and Docker in production
• Infrastructure as Code: proficiency with Terraform or CloudFormation

• Strong understanding of encryption, secret management, and network security
• Experience embedding security controls into build, deploy, and runtime workflows

• Experience with Harness (or comparable CD tooling) and Git-based workflows
• Strong version control practices with Git

• Working knowledge of Apache Spark core concepts: RDDs, DataFrames, Spark SQL
• Proficiency in SQL and experience with relational databases
• 5+ years of software development experience in a JVM environment (Java, Kotlin, Scala) with exposure to functional programming concepts
• Strong problem-solving, analytical, communication, and collaboration skills

• Prior experience with federal or regulated (healthcare) cloud programs
• Deep Scala ecosystem knowledge (frameworks and libraries)
• Experience scaling big-data pipelines and observability for Spark/EMR
• Familiarity with cloud security frameworks and compliance (e.g., FedRAMP, NIST 800-53)

• Must be able to obtain and maintain a Public Trust clearance
• Must be authorized to work in the United States without sponsorship
• US citizenship required
