Develops ballistic and hypersonic missile kinematic threat models for modeling and simulation frameworks. Applies engineering and mathematical algorithms to model vehicle behavior, trajectories, aerodynamic forces, guidance, navigation, and control. Researches missile parameters, staging debris, countermeasures, and payload traits; authors technical verification and validation documentation; collaborates with engineering and testing stakeholders; and supports time-critical product deliveries.

Designs, models, simulates, analyzes, and tests RF, microwave, payload, and communications systems. Responsibilities include RF architecture, antenna, transmitter and receiver design, link budget and cascade analysis, system trades, requirements development, proposal estimates, and satellite communications analysis. The role requires MATLAB proficiency, digital communications and signal-processing knowledge, RF system modeling experience, and an active Secret clearance. Preferred experience includes SATCOM, digital beamforming, test instrumentation, Simulink, MBSE, DOORS, STK, and HFSS.

Lead a systems engineering team supporting Sentinel weapon system deployment. Responsibilities include requirements development and allocation, functional decomposition, interface definition, verification and validation, traceability, systems architecture modeling, and MBSE process development. The role also supports lifecycle cost modeling, sustainability, logistics, system safety, human factors, RAM-C, and stakeholder collaboration across the ground segment of an ICBM system.

The Principal Systems Engineer will support Sentinel requirements engineering and verification strategy. Responsibilities include maintaining system-level requirements, decomposing and allocating lower-level requirements, managing requirements information with MBSE tools, coordinating verification across engineering teams, reporting status to leadership, and collaborating with government stakeholders. The role requires DOORS experience, systems engineering expertise, an active Secret clearance, and the ability to obtain SAP approval.

Administer and harden Windows and Linux systems supporting mission-critical classified workflows. Configure and maintain Atlassian tools, deploy Kubernetes and containerized workloads, and manage IPA and Active Directory identity services. Develop Bash and Python automation for operations, patching, and workflow execution. Provide Tier 2/3 support, root cause analysis, documentation, and runbook maintenance. The role also supports virtualization, VDI, infrastructure-as-code, configuration management, and security hardening.

Designs, develops, and maintains PostgreSQL databases across production and test environments. The role architects database instances, supports Docker Swarm deployments, investigates incidents, builds database access layers and automation, and promotes software engineering best practices. Responsibilities include Agile participation, GitLab-based development and CI/CD, Jira and Confluence usage, collaboration with product, QA, and DevOps teams, and mentoring junior and mid-level engineers. Advanced PostgreSQL, Python, Linux, relational database, and software development lifecycle experience are required.

Develop and optimize radar digital signal processing software for identifying and tracking objects in geosynchronous orbit. Responsibilities include designing, testing, debugging, and documenting software; developing DSP algorithms and pipelines; optimizing GPU-accelerated workloads with CUDA and NVIDIA MatX; collaborating with hardware and multidisciplinary engineering teams; and applying AI-enabled development tools while maintaining code quality and accountability.

Develop and update algorithms and analytical tools for missile defense and space domain awareness data. Work within an Agile Scrum team to deliver software features, conduct systems and software analysis, support verification of complex defense systems, prepare authoritative technical reports, and contribute to technical reviews and briefings. The role requires on-site work in Colorado Springs and Schriever SFB while supporting the C2BMC missile defense program.

Serves as Scrum Master and software engineer for the C2BMC Planner product team. Facilitates Agile ceremonies, PI planning, feature decomposition, backlog refinement, and cross-team dependency management. Spends approximately 70% of the role designing, coding, testing, debugging, and maintaining Java applications, CI/CD pipelines, and automation tools. Supports mission-critical missile defense software while meeting performance, security, reliability, and delivery objectives.

Serve as systems engineering technical lead across lifecycle phases: own technical baseline, translate CONOPS into requirements and design, coordinate multi-discipline teams, develop integration/V&V/test plans, use MBSE and modeling for trade studies, identify/mitigate risks, present results to stakeholders, and support proposals and estimates.
