CesiumAstro develops advanced communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We are seeking a Spectrum Engineer II to join our dynamic, cross-functional team in a hands-on role focused on satellite spectrum engineering, regulatory compliance, and systems analysis.
In this role, you will perform critical spectrum analyses including satellite interference, equivalent power flux-density (EPFD), power flux-density (PFD), and link budget analyses to assess spectrum-sharing compatibility and regulatory compliance for non-geostationary satellite orbit (NGSO) systems. You will prepare comprehensive technical analyses, system parameters, and supporting documentation for ITU filings, FCC applications, international market-access requests, and earth-station licensing activities, including Schedule S and license modifications.
You will support satellite network coordination and regulatory proceedings by preparing interference studies, technical correspondence, and briefing materials while participating in external engagements. Additionally, you will assist with the design and development of communications system architectures, interfaces, subsystems, and performance models. Your responsibilities include performing system modeling, link analysis, performance evaluation, trade studies, simulation, and system integration activities.
You will review system requirements, interface specifications, architecture documentation, and analytical results supporting system implementation. Verification, validation, testing, simulation, integration, and troubleshooting activities are core to this position. You will analyze simulation results, system performance data, and test results to identify trends and recommend solutions, and support root cause investigations and corrective actions.
Collaboration is essential—you will work closely with systems, software, RF, electrical, mechanical, integration and test, quality, and program teams throughout product development. You will prepare technical documentation, interface control documentation, verification reports, and engineering change documentation. Participation in design reviews, technical investigations, customer support activities, and verification activities is expected. You will review communications systems engineering methods and development activities to identify improvement opportunities and contribute to continuous improvement initiatives.
REQUIREMENTS:
- Bachelor's degree in aerospace engineering, electrical engineering, systems engineering, computer engineering, or related engineering field with 2–5 years of related experience; OR Master's degree with 0–3 years of related experience in communications systems engineering, system architecture, RF systems, systems integration, or related engineering discipline.
- Working knowledge of communications systems, systems engineering principles, system architecture, requirements development, and interface management.
- Experience with systems modeling, link analysis, performance evaluation, simulation tools, and engineering analysis methods.
- Understanding of digital communications, RF fundamentals, networking concepts, signal processing, interface development, and system integration.
- Knowledge of satellite spectrum engineering, ITU and FCC regulatory requirements, spectrum-sharing principles, satellite network coordination, and licensing processes.
- Experience with satellite interference analysis, EPFD/PFD modeling, link budgets, NGSO/GSO coexistence considerations, and preparation of technical documentation supporting regulatory filings.
- Knowledge of systems engineering processes, verification methodologies, engineering documentation, technical standards, and requirements management.
- Familiarity with modeling and simulation, product development, configuration management, and multidisciplinary engineering collaboration.
- Proficiency with Microsoft Office Suite (Outlook, Word, Excel, PowerPoint, Teams).
- Experience with engineering analysis and modeling tools such as MATLAB, Simulink, STK, Python, or equivalent.
- Experience with engineering documentation, requirements management, and collaboration tools such as DOORS, Jira, Confluence, or equivalent.
- Experience with satellite interference analysis, spectrum coordination, and regulatory filing applications such as Visualyse, FCC filing systems, ITU filing software and databases, or equivalent.
- Must be a U.S. citizen, lawful permanent resident, conditional resident, asylee, or refugee, or eligible to obtain required authorizations from the U.S. Department of State.
