• Collaborate with design and test engineering teams to develop test requirements, map requirements to reusable test architectures and procedures, implement test plans and procedures, and log and present results to key stakeholders.
• Operate and maintain RF test equipment, including spectrum analyzers, network analyzers, signal generators, and oscilloscopes.
• Participate in “design for test” planning and review from the early stages of RF product development.
• Review, interpret, and approve RF test data and results.
• Work closely with senior engineers and cross-functional teams to support the full product lifecycle.
• Contribute and participate in root cause analysis, anomaly investigations, and failure review boards, where necessary.

• A Bachelor of Science (BS) or Master of Science (MS) degree in Mechanical Engineering, Aerospace Engineering, or a related technical discipline from an accredited university.
• 2 years of relevant industry or research experience covering several of the responsibilities listed.
• Hands-on experience with lab instruments such as digital oscilloscopes, spectrum analyzers, RF signal generators, and vector signal analyzers.
• Working knowledge of RF measurements, test equipment (VSAs, VSGs, VNAs, etc.), test architectures, and automation. 
• Excellent written and spoken communication skills.
• Excellent organizational and time management skills.

• Space industry experience.
• Familiarity or hands-on experience with phased array testing.
• Programming or scripting experience (Python, MATLAB, C/C , etc.).
• Understanding of RF and mixed-signal hardware (e.g. amplifiers, filters, ADCs/DACs, antennas) and its effects on test design.
