About The Position

The Lead DevSecOps Engineer is a strategic and hands-on technical leader responsible for building and advancing the DevSecOps practices, infrastructure, automation, and integration capabilities that support complex DoD software systems. This role leads the design and execution of CI/CD pipelines, system integration testing, test automation, and secure, scalable deployment infrastructure while mentoring engineering teams and ensuring alignment with security and compliance requirements. The Lead DevSecOps Engineer also drives reusable engineering practices, tooling, and deployment patterns that improve consistency, efficiency, and scalability across programs and the broader portfolio. This position supports the Beyond Line of Sight (BLOS) Engagement Controller and Manager (BECM) program and requires strong software integration engineering, test engineering, and DevSecOps experience to support integration, verification, automation, and documentation efforts in classified, highly regulated environments.

Requirements

A degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 5 years of relevant experience, or an advanced degree in a related field and a minimum of 3 years of experience
2+ years in a technical leadership role
Demonstrated experience leading system integration and test efforts across multiple subsystems or external systems
Demonstrated experience designing and building test automation frameworks, harnesses, or test utilities, not just authoring test cases against existing tooling
Demonstrated experience leading DevSecOps adoption in secure, regulated environments
Experience building tooling or infrastructure intended for reuse across more than one program, team, or product line
Experience working in cross-functional software development teams
Expertise in at least one major public cloud provider (AWS or GCP preferred)
Experience designing, implementing, and/or supporting cloud native container orchestration platforms and technologies (e.g., Kubernetes, Istio, Helm, Podman, Docker, ArgoCD, Flux)
Proficiency with Python and testing frameworks such as Pytest; Linux shell scripting and core CLI tooling (grep, awk, sed, ssh, scp); automation pipeline development using tools such as GitLab and Artifactory
Experience creating test threads, cases, and steps for SWIT and/or SIT
Active and transferable TS/SCI U.S. government issued security clearance required prior to start date
U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance

Nice To Haves

Experience testing distributed, real-time, or message-driven systems where timing and ordering matter
Experience building interface simulators or emulators for systems unavailable in the lab
Experience with test reporting and results aggregation standards (e.g., JUnit XML, CTRF, Allure)
Experience with behavior-driven test formats (Gherkin, Cucumber) as a shared artifact between engineering and stakeholders
Experience with data integration and streaming technologies, including NiFi, Kafka, and REST APIs
Experience with documentation tools like Swagger
Experience with modeling tools like Cameo
AWS Certified Solutions Architect Associate certification
Certified Kubernetes Administrator certification
DoD IAT Level II security certification (Security+ CE, GSEC, SSCP, or CCNA Security)

Responsibilities

Own system integration testing (SIT) across multiple internal subsystems and external systems, identifying issues related to interface contracts, data exchange, timing, usability, functionality, safety, and security
Define and maintain SWIT and SIT test threads, cases, and steps, and drive traceability from requirements through verification evidence
Lead integration events with external system owners and government stakeholders, including dry runs, formal test events, and site acceptance activities
Triage integration defects to root cause across system boundaries and drive them to closure with the responsible team
Design, build, and maintain test tooling as a first-class engineering product: simulators, stubs, message injectors, data generators, log analyzers, and results reporting
Develop automated test suites and utilities, and keep them current as subsystems and external interfaces evolve
Build and maintain automated regression capability integrated into CI/CD, so integration failures surface early rather than at test events
Establish standard test reporting and evidence artifacts that satisfy both engineering and compliance consumers
Design integration and test capabilities for reuse, so tooling, harnesses, pipeline templates, and deployment patterns built for BECM can be adopted by adjacent programs with minimal rework
Identify duplicated effort across programs and consolidate it into shared, versioned, documented components
Define and champion common standards for interface documentation, test structure, and environment configuration across the engineering organization
Serve as a technical point of contact for other program teams adopting these capabilities
Use container technologies to configure and deploy software to lab, integration, and customer site environments
Build and maintain automation pipelines, artifact management, and environment provisioning for both connected and disconnected/classified enclaves
Embed security and compliance controls into the pipeline rather than bolting them on at the end
Collaborate with cross-functional teams to define, design, and implement new software and its verification approach
Write and maintain comprehensive documentation for integration, test, and deployment processes
Mentor engineers on integration engineering, test design, and automation practice
Stay current with industry trends in software integration, test engineering, and secure delivery
