Sr. Test Engineer
About the role
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.
About 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.
Must 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.
Nice to Haves
- Experience in Signal Processing algorithms
