Lead Systems Integration & DevSecOps Engineer

About the role

Lyntris is a defense technology company that connects sensing to action across the connected battlespace. This position will be onsite at a facility in Sterling, VA and requires an active U.S. national security clearance.

Responsibilities

The Lead Systems Integration & DevSecOps Engineer is a strategic and hands-on role responsible for owning system integration testing, building the tooling and automation that makes that testing repeatable, and architecting secure, scalable infrastructure in support of complex DoD software systems.

• 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
• 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

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

Preferred Qualifications

• 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)
