  • Rapidly understand, troubleshoot, recreate, and solve customer-reported anomalies.
  • Develop processes and procedures to structure product development and application.
  • Become a technical expert in Cesium's products in depth to execute the above. This includes state-of-the-art RF, digital, and power electronics; embedded software; FPGAs; DSP; mechanical integration; and end-to-end wireless communication links.
  • Provide technical leadership and direction to the Business Development Team

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
  • At least 7 years of relevant experience in technical product development or application support.
  • Working knowledge of RF electronics and communication systems.

  • Work samples of technical communication, such as public app notes or user manuals.
  • Experience with high-reliability electronics, such as aerospace.
  • Experience with small satellites.
  • Experience in technical product planning, marketing, or sales.
