Requires secure clearances and on-site Colorado Springs presence.

Full‑Stack Software Engineer working on a Defense/Aerospace program supporting Advanced Battle Management. Advance a Java baseline in a small distributed team, develop containerized applications (Docker/Kubernetes) on Linux/Unix using Agile practices, comply with security requirements (active TS/SCI, Security+), and collaborate with partners. Limited travel (~10%).

Lead architecture and implementation of reusable software components for a multi‑variant product line. Elicit, analyze, and trace system-level requirements; define ICDs and create use-case/activity/sequence models. Work with Agile teams to translate requirements into user stories, oversee integration/verification across variants, and improve engineering processes and tooling.

Lead a geographically distributed systems engineering team to develop requirements and architectures for complex hardware/software subsystems. Coordinate across hardware, software, and test disciplines, drive stakeholder consensus, manage tasking and priorities, and deliver integrated subsystem capabilities for the Sentinel ICBM program.

Senior systems engineer responsible for designing, developing, and maintaining bidirectional integrations across systems engineering toolchains (JIRA, DOORS, Cameo, GitLab). Build APIs/connectors, automated scripts and CI/CD workflows to enable traceability and data synchronization, validate and tune pipelines, and support configuration management, QA, and cybersecurity compliance in a classified, on-site defense environment.

Support systems engineering across the full V-model for missile defense, space, and intelligence programs. Develop systems engineering artifacts, perform modeling, simulation, analysis, trade studies, verification/validation, and communicate technical results to technical and non-technical stakeholders. Work autonomously and collaboratively, travel up to 10%.

Develop and maintain CNO software tools and end-to-end data flows. Program in Assembly, C, C++, Java, Perl, or Python. Build Windows, UNIX, embedded, or mobile applications, author documentation, participate in design/code reviews, and troubleshoot and debug systems.
