Profile match
CesiumAstro is an American company founded in Austin in 2017 that builds active phased array communications payloads for satellites, aircraft and defence platforms. Its systems are software-defined and electronically steered, which lets a moving platform track several links at once without mechanical antennas, and the company manufactures them in house rather than integrating third-party subsystems. It sells mainly to defence customers and satellite operators, has raised venture funding from investors including Airbus Ventures and Lightspeed, and operates facilities in Austin, Colorado and the United Kingdom.

We are looking to add a Spectrum Engineer II to our team. In this role you will support the design, development, integration, and testing of communications systems, including satellite spectrum coordination and regulatory compliance activities. This role performs communications system analyses, evaluates performance and interference considerations, and prepares technical documentation supporting system development, and licensing requirements. Using established engineering methods and regulatory guidelines, the Spectrum Engineer II resolves routine technical challenges and supports compliance with International Telecommunication Union (ITU) and Federal Communications Commission (FCC) requirements.

Working cross-functionally with systems, software, RF, electrical, mechanical, integration and test, quality, regulatory, and program teams, this role supports communications systems engineering from concept development through integration, verification, and production while contributing to satellite licensing, regulatory filings, and spectrum coordination activities.

JOB DUTIES AND RESPONSIBILITIES

  • Perform satellite interference, equivalent power flux-density (EPFD), power flux-density (PFD), and link budget analyses to assess spectrum-sharing compatibility and regulatory compliance, including non-geostationary satellite orbit (NGSO) systems.
  • Prepare 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.
  • Support satellite network coordination and regulatory proceedings by preparing interference studies, technical correspondence, and briefing materials while participating in external engagements under the Director's guidance.
  • Assist with the design and development of communications system architectures, interfaces, subsystems, and performance models.
  • Perform system modeling, link analysis, performance evaluation, trade studies, simulation, and system integration activities.
  • Review system requirements, interface specifications, architecture documentation, analytical results, and technical documentation supporting system implementation.
  • Perform verification, validation, testing, simulation, integration, and troubleshooting activities.
  • Analyze simulation results, system performance data, test results, and engineering observations to identify trends and recommend solutions.
  • Support root cause investigations, engineering changes, system improvements, defect resolution, and corrective actions.
  • Collaborate with systems, software, RF, electrical, mechanical, integration and test, quality, and program teams throughout product development.
  • Prepare technical documentation, interface control documentation, verification reports, engineering reports, and engineering change documentation.
  • Participate in design reviews, technical investigations, customer support activities, system integration, and verification activities.
  • Review communications systems engineering methods, modeling practices, requirements management processes, and development activities to identify improvement opportunities.
  • Apply engineering standards, company procedures, customer requirements, and systems engineering best practices throughout the product lifecycle.
  • Contribute to continuous improvement initiatives that strengthen system performance, requirements quality, modeling accuracy, and engineering effectiveness.

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

  • Bachelor's degree in aerospace engineering, electrical engineering, systems engineering, computer engineering, or a 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 a 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.
  • Microsoft Office Suite including Outlook, Word, Excel, PowerPoint, and Teams.
  • Engineering analysis and modeling tools, e.g. MATLAB, Simulink, STK, Python, or equivalent applications.
  • Engineering documentation, requirements management, and collaboration tools, e.g. DOORS, Jira, Confluence, or equivalent applications.
  • Satellite interference analysis, spectrum coordination, and regulatory filing applications, e.g. Visualyse, FCC filing systems, ITU filing software and databases, or equivalent applications.
