Senior Systems Engineer responsible for conducting systems and system-of-systems architecture design, integration, testing, and certification across complex defense technical environments. Duties include technical requirements definition, data analysis from multiple sources, test plan and technical documentation development, and troubleshooting across multiple operating systems and virtualized environments. Requires minimum 10 years of systems engineering or technical integration experience, strong analytical and critical thinking skills, and proficiency with Microsoft Office applications.

A Junior Operating Systems Engineer will build and maintain custom Linux images using Yocto Project (recipes, layers, BitBake, kernel configuration), supporting immutable A/B-updatable OS architectures with secure boot and update tooling. The role involves packaging, integrating, and troubleshooting system services, drivers, and third-party software on embedded x86 hardware, as well as contributing to OS hardening (FIPS mode, secure boot, compliance configuration). Daily use of generative AI tools will accelerate development tasks including recipe writing, test scaffolding, and debugging. The engineer will debug boot, kernel, driver, and userspace issues on real appliance hardware and document build processes, image releases, and provisioning workflows.

Lyntris seeks a Cyber Security Engineer II to provide Risk Management Framework (RMF) Assessment and Authorization (A&A) support for Navy software solutions. The role involves designing, implementing, and monitoring cybersecurity and information assurance policies for mission-critical systems; developing system IA documentation (categorization forms, security plans, assessment plans, continuous monitoring plans, risk assessments); and guiding the software development team through security scan review, evaluation, and remediation. The engineer will work with system owners and stakeholders to manage cybersecurity requirements and continuously improve cyber posture. Requires 2–3 years of Department of Navy accreditation experience and working knowledge of NIST standards, RMF, and eMASS.

Senior DevOps / Platform Engineer (Level III) responsible for designing and maintaining CI/CD pipelines, automating infrastructure for predictable environments, and supporting containerized platforms in secure, regulated defense settings.
