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.

  • Provide guidance to employees and program personnel on classified information handling, security procedures, reporting obligations, and established compliance requirements.
  • Monitor changes to government security regulations, contractual requirements, and internal policies to assess potential impacts to assigned security activities.
  • Maintain security procedures, training materials, compliance records, and operational documentation in accordance with established requirements.
  • Recommend improvements to security processes, documentation practices, access controls, and compliance activities that strengthen operational effectiveness and security awareness.
