Sr. Communication Systems Engineer with Security Clearance

The Aerospace Corporation is the trusted partner to the nation's space programs, solving the hardest problems and providing unmatched technical expertise. As the operator of a federally funded research and development center (FFRDC), we are broadly engaged across all aspects of space- delivering innovative solutions that span satellite, launch, ground, and cyber systems for defense, civil and commercial customers. When you join our team, you'll be part of a special collection of problem solvers, thought leaders, and innovators. Join us and take your place in space.

The Defense Systems Group (DSG) provides analysis-based decision support to senior leaders on space architectures, policy and strategy, technology development, warfighter capability enablers, systems integration, defense industrial base, and threat reduction to help shape existing and future space missions across the national security space (NSS) enterprise. DSG is unique at Aerospace as it not only directly supports major customers, including the U.S. Space Force, U.S.

Space Command, Air Force Material Command, and senior leadership at the Pentagon, but also provides a broad range of technical support across the national space enterprise, maintaining vertical responsibilities with customers' portfolios as well as horizontal, matrixed responsibilities across the corporation. Additionally, DSG provides deep technical expertise to the Space Force Space Systems Command (SSC) in the conception, design, acquisition, launch and operations of satellite, launch vehicle, ground control, and range systems.

Join the Special Programs Division of Aerospace's Defense Systems Group to directly influence the next era of national security. As an Aerospace Sr. Communication Systems Engineer working with the United States Space Force (USSF) Rapid Reaction Branch (RRB) team, you will work closely with the government Test Director as a principal technical leader for high-stakes test and evaluation (T&E) initiatives.

In this role, you will bridge the gap between warfighter requirements and mission reality-ensuring our next-generation communication, electromagnetic warfare, and cyber systems are fully prepared to dominate in contested space environments. The selected candidate will be required to work full-time, on-site at the facility for RRB near Aerospace's campus in Colorado Springs, CO. What You'll Be Doing

• Deliver Rapid Capabilities: Serve as a core member of a mission-focused team fielding high-priority capabilities against Urgent Operational Needs (UONs) for Combatant Commands.
• Drive T&E Strategy: Act as the subject matter authority for testing rapidly fielded USSF systems - supervising test planning, execution, and reporting while developing innovative T&E approaches to evaluate tactics, techniques, and procedures (TTPs) against emerging threats.
• Direct Theater Test Operations: Lead developmental test execution at deployed locations, adapting to evolving conditions while overseeing data collection, analysis, daily situation reports (SITREPs), and final test reporting.
• Secure & Coordinate Test Resources: Partner with RRB development teams to identify necessary resources and engage the 25th Space Range Squadron (25 SRS) and the Operational Test and Training Infrastructure (OTTI) Program Executive Office (PEO) to secure test and training environments.
• Author High-Level Approval Packages: Draft sensitive T&E approval documentation - up to the Secretary of Defense (SECDEF) or Secretary of the Air Force (SECAF) levels - coordinating across acquisition, intelligence, legal, and operational stakeholders to validate TTPs in the field.
• Lead Test Readiness Reviews: Own test readiness review (TRR) planning and execution, from scheduling and board coordination through documentation, presentation, and action closure.
• Provide Technical Authority & Mentorship: Brief senior leadership and mission partners on high-impact findings and mentor the next generation of space engineers. What You Need to be Successful Minimum Requirements for Sr. Project Engineer - Communications Systems Engineering:
• Bachelor's degree in engineering, computer science, physics, mathematics, or a related technical discipline
• 10 or more years of hands-on engineering experience, featuring deep domain expertise in testing RF systems, signal processing, or satellite communications within defense/government programs.
• Willingness and ability to travel up to 15% of the time to engage with key stakeholders, mission partners, and deployed test sites, which include locations that are outside the contiguous United States (OCONUS).
• This position requires an active TS/SCI security clearance and the ability to be granted and maintain accesses to Special Access Programs (SAPs), issued by the US government. US citizenship is required to obtain a security clearance. How You Can Stand Out It would be impressive if you have one or more of these:
• SAP Access: Current or prior access to SAPs.
• EW/Cyber T&E: Proven track record in applying DoD test and evaluation principles to communication, electromagnetic warfare (EW), and cyber operation systems across US Space Force architectures.
• Test Documentation: Skilled in authoring test plans and procedures, leading data collection and analysis, documenting discrepancies/corrective actions, and delivering decision-ready test reports.
• SATCOM/VSAT: Hands-on experience operating, maintaining, and troubleshooting satellite communication (SATCOM) systems - including very small aperture terminal (VSAT) equipment - in deployed environments.
• Technical Toolset: Proficiency in Linux, network analysis tools (e.g., Wireshark), and Python for scripting test events, real-time monitoring, and log analysis.
