Senior Devops Engineer

Senior Systems Integration & DevSecOps EngineerThe Senior Systems Integration & DevSecOps Engineer is a hands-on engineering role focused on integrating and testing complex DoD software systems, building the tooling that makes that testing repeatable, and maintaining the secure pipelines and environments those systems deploy into. This engineer works across subsystem and external system boundaries, writes the automation that catches integration problems before formal test events, and builds tooling with an eye toward reuse beyond a single program.This position supports the Beyond Line of Sight (BLOS) Engagement Controller and Manager (BECM) program and requires solid software integration engineering, test engineering, and DevSecOps experience in classified, highly regulated environments.Work Environment: Full-time on-site in Sterling, VA, split between standard office space and SCIF work. Flexible daily start and end times, coordinated with program needs and facility access windows.Duties & ResponsibilitiesSystem Integration & TestIntegrate and test software subsystems and external systems, identifying issues related to interface contracts, data exchange, timing, usability, functionality, safety, and securityWrite and maintain SWIT and SIT test threads, cases, and steps, and support traceability from requirements through verification evidenceParticipate in integration events with external system owners and government stakeholders, including dry runs, formal test events, and site activitiesTriage integration defects across system boundaries, isolate root cause, and work with the responsible team to drive closureTest Tooling & AutomationBuild and maintain test tooling: simulators, stubs, message injectors, data generators, log analyzers, and results reportingDevelop automated test suites and utilities, and keep them current as subsystems and external interfaces changeExtend automated regression coverage inside CI/CD so integration failures surface early rather than at test eventsProduce consistent test reporting and evidence artifacts for both engineering and compliance consumersReusable EngineeringBuild tooling and test assets as versioned, documented components rather than one-off scripts, so they hold up when another program picks them upFlag duplicated effort across teams and help consolidate it into shared componentsContribute to common conventions for interface documentation, test structure, and environment configurationInfrastructure & DevSecOpsUse container technologies to configure and deploy software to lab, integration, and customer site environmentsBuild and maintain automation pipelines, artifact management, and environment provisioning, including disconnected and classified enclavesImplement security and compliance controls inside the pipeline rather than at the end of the cycleCollaboration & DocumentationWork with cross-functional teams to define, design, and implement new software and its verification approachWrite and maintain documentation for integration, test, and deployment processesShare integration and test practices with less experienced engineers on the teamStay current with developments in software integration, test engineering, and secure deliveryRequired QualificationsA 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 experienceHands-on experience integrating and testing software across subsystem or external system boundariesExperience building test automation, harnesses, or test utilities, not only authoring test cases against existing toolingExperience working in secure or regulated software environmentsExperience working in cross-functional software development teamsWorking knowledge of at least one major public cloud provider (AWS or GCP preferred)Experience with container and orchestration technologies (e.g., Kubernetes, Docker, Podman, Helm, ArgoCD, Flux)Proficiency with Python and testing frameworks such as Pytest; Linux shell scripting and core CLI tooling (grep, awk, sed, ssh, scp); pipeline development using tools such as GitLab and ArtifactoryExperience creating test threads, cases, and steps for SWIT and/or SITActive and transferable TS/SCI U.S. government issued security clearance required prior to start dateU.S. citizenship is required, as only U.S. citizens are eligible for a security clearancePreferred QualificationsExperience testing distributed, real-time, or message-driven systems where timing and ordering matterExperience building interface simulators or emulators for systems unavailable in the labExperience with test reporting and results aggregation standards (e.g., JUnit XML, CTRF, Allure)Experience with behavior-driven test formats (Gherkin, Cucumber)Experience with data integration and streaming technologies, including NiFi, Kafka, and REST APIsExperience mentoring engineers or leading a small technical effortExperience with documentation tools like SwaggerExperience with modeling tools like CameoAWS Certified Solutions Architect Associate certificationCertified Kubernetes Administrator certificationDoD IAT Level II security certification (Security+ CE, GSEC, SSCP, or CCNA Security)Physical RequirementsProlonged periods sitting at a desk and working on a computer.Must be able to lift up to 15 pounds at times.This position has an on-site requirement of 5 days per week at a secure controlled information facility in Sterling, VA.Clearance RequirementsSome positions will require access to U.S. National Security information.
