Radio Frequency (RF) Test Engineer

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.

This is a ONSITE, FULL-TIME position based in Seattle, WA.

AN IDEAL CANDIDATE MEETS OUR VALUES:

• A Sense of Urgency: Lead projects from concept to reality, rapidly and effectively
• First Principles Engineering: Have a strong understanding of the whys behind the "what's"; have the ability to extrapolate from first principles to complex system design
• High Learning Agility: Love to learn; have a grounded approach to recognizing your weaknesses and take the initiative to brush up on and sharpen your engineering foundations to better collaborate with your teammates with different backgrounds
• System-Level Design and Analysis: Understand the requirements flow down process and be able to quickly iterate on evolving requirements
• Excellent Communication Skills: Effectively convey ideas and communicate technical topics with engineering, build staff, and operations; run self-directed design reviews and participate in reviews of parallel systems
• Anticipation of Needs: Identify problems, think creatively, and rapidly produce reliable and cost-effective solutions to meet the ever growing and changing needs of an early-stage company

BASIC QUALIFICATIONS

• 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

STRONGLY DESIRED

• Experience with environmental testing such as thermal, vibration, and TVAC
• Experience in high-volume manufacturing, assembling, and testing of electronic components
• Experience developing automated test systems and test fixtures for production environments
• Experience analyzing the impact of radiation on electronic components and strategies to mitigate it
• Familiarity with NASA and MIL-spec test and workmanship standards for space hardware (e.g., MIL-STD-810/883, NASA/IPC J-STD-001ES)
