Radio Frequency (RF) Test Engineer

Hubble Network•Seattle, WA

4h•$105,000 - $175,000•Onsite

About The Position

As a Radio Frequency (RF) Test Engineer at Hubble, you'll help ensure the reliability, performance, and longevity of our satellite hardware. You'll develop and execute the test, validation, and quality-assurance strategies that qualify our wireless payloads, uncover weaknesses, and prove that our hardware can thrive in the harshest environments space has to offer — including radiation, thermal cycling, and mechanical stress. Your work will span the full lifecycle — from design validation through flight readiness and into volume production — and will be central to scaling reliable, mission-ready hardware as we build out the Hubble satellite constellation. You'll work closely with cross-functional hardware, software, and mechanical teams to ensure reliability from initial design through manufacturing and in-orbit operation.

Requirements

Bachelor's Degree in Electrical Engineering, Aerospace Engineering, Computer Science, or a related field
3+ years of experience in hardware validation, test engineering, or RF systems testing
Experience in design, testing, and debugging of RF PCBAs, coupled with a thorough understanding of electronics reliability and failure mechanisms
Experience with test equipment (oscilloscope, VNA, spectrum analyzer, signal generator) and procedures for analysis, verification, and validation of RF products
Strong expertise in programming languages (Python, C/C++) for data analysis and test automation
Demonstrated ability to conduct root-cause failure analysis and implement corrective actions, with an emphasis on RF systems
Thorough understanding of metrology, sources of measurement error, and uncertainty analysis
Demonstrated ability to analyze system requirements, decompose them into verifiable test cases, and maintain bidirectional traceability using industry-standard tools (e.g., Jira)
Demonstrated ability to work in a highly cross-functional role
Ability to work independently
Strong interpersonal, verbal, and written communication skills
Ability and willingness to thrive in a fast-paced, rapidly changing work environment
Must be a U.S. citizen or lawful permanent resident ('green card holder') as defined by ITAR.
