[Hiring] Senior DevSecOps Engineer @One Dynamic

Role Description

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.

• Experience securing and scaling Amazon EMR (Spark) and OpenSearch

• 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

Requirements

• 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

Benefits

• Competitive compensation: $135K–$150K
• High-impact work on mission-critical federal programs
• Collaborative, engineering-driven culture
