§ 01OVERVIEW
Wanna join the adventure?

As our new RF AIT (Radio Frequency Assembly, Integration, and Test) Engineer, you will play a pivotal role in the development, assembly, integration, and testing of RF (Radio Frequency) systems and components for Loft space missions. This role requires a strong background in RF engineering, electrical engineering, and space technology.

§ 02ABOUT THE ROLE
  • Lead the assembly and integration of RF subsystems and components into the spacecraft.
  • Ensure proper installation, wiring, and connectivity of RF hardware according to design specifications.
  • Develop test plans and procedures for RF systems and components.
  • Conduct comprehensive RF tests to verify system performance, including sensitivity, signal-to-noise ratio, and frequency response.
  • Troubleshoot and resolve RF hardware issues during testing.
  • Prepare RF hardware for environmental testing, including thermal vacuum testing, vibration testing, and electromagnetic interference (EMI)/electromagnetic compatibility (EMC) testing.
  • Analyze and report on environmental test results to ensure RF systems meet specified requirements.
  • Collaborate with RF system architects and design engineers to perform system analysis and simulations for performance optimization.
  • Work closely with cross-functional teams, including electrical engineers, mechanical engineers, and system engineers, to integrate RF systems into spacecraft successfully.
  • Hands-on experience with space hardware and spaceflight antennas, with a strong understanding of design intent.
  • Proficiency in test engineering, including test design, validation, execution, and troubleshooting.
  • Experience with tests such as EMI/EMC, GNC GPS testing, and TTNC (tracking telemetry and control).
  • Knowledge of relevant software for testing and analysis.
  • Familiarity with electrical check-out procedures and environments, though emphasis lies more on rigorous testing rather than environmental testing.
§ 03MUST HAVES
  • Bachelor’s degree in Electrical Engineering, Aerospace Engineering, or a related field. Master’s degree preferred.
  • Minimum of 5 years of experience in RF subsystem testing and integration.
  • Proven experience in RF system integration, simulation, and performance analysis.
  • Experience in payload RF systems, transceiver, and amplifier design.
  • Proven experience with RF testing tools (VNA, Spectrum Analyzer, RF chamber)
  • Knowledge in EMI/EMC characterization is a real plus for this position
  • Excellent communication and teamwork skills.
§ 04NICE TO HAVES

  • Experience in Signal Processing algorithms
