Leads the enterprise security function, including hiring and developing security engineers across enterprise security, vulnerability management, and Linux security. Owns security strategy, roadmaps, vulnerability management, identity, hardening, cloud, OT, and compliance initiatives. Partners with IT, DevOps, engineering, and manufacturing stakeholders, oversees incident response and on-call operations, communicates risk to leadership, and provides technical guidance on identity architecture, CIS/STIG baselines, SIEM, detection, and cloud security.

Develop and test flight software for spacecraft computers, integrate GNC algorithms, maintain command telemetry databases, support command scripting, build subsystem simulators, and create device drivers and communications libraries. The role involves embedded RTOS development, hardware integration, mission testing, and collaboration with ground-control software teams. This is a three-month onsite temporary engagement in Denver or Long Beach, with potential conversion to regular employment.

Develop and maintain modern C++ spacecraft simulation software and multi-physics libraries. Model spacecraft dynamics, thermal systems, attitude control, propulsion, power, sensors, and actuators; implement numerical solvers and time-stepping algorithms; maintain Python and C++ APIs; and collaborate on mission planning, algorithm development, testing, code reviews, and sprint planning.

Analyze manufacturing and spacecraft telemetry to identify anomalies, test failures, and degradation patterns. Build predictive models, SQL queries, operational dashboards, statistical process controls, and visualizations using Python and related tools. Document reproducible analyses in Jupyter notebooks and communicate findings to engineering, manufacturing, and mission operations teams. This is a three-month temporary, potentially convertible role supporting hardware production and spacecraft operations.

Performs hands-on assembly, integration, configuration, and testing of electrical systems, test rigs, and ground support equipment for spacecraft and propulsion campaigns. Conducts continuity checks, circuit verification, functional tests, troubleshooting, inspections, and anomaly investigations. Maintains tooling, instrumentation, inventories, calibration records, and test-site readiness while documenting nonconformances and supporting electrical safety and ESD compliance. The role is fully onsite in Centennial, Colorado, with regular travel between headquarters and remote test sites.

Design, build, and lead scalable data platforms, pipelines, data products, and ELT/ETL processes supporting analytics and AI/ML workloads. Establish standards for data quality, testing, monitoring, observability, CI/CD, security, and reliability. Own projects through deployment and production support, collaborate across technical and business teams, use AI-assisted engineering tools, and mentor data engineers.
