About The Position

Join Apple’s Wireless team and help build the technology that makes its radios possible. The Instrument Engineering team designs and produces precision RF and analog test equipment used to calibrate and validate cellular (5G/4G and legacy), Wi-Fi, Bluetooth, mmWave, UWB, and NFC radios across iPhone, iPad, Mac, and Apple Watch products. The role works closely with RF, software, and signal processing engineers, as well as internal customers, to take equipment from concept through mass production to Apple’s standards.

This hands-on RF position combines bench debugging, RF applications support, customer engagement, and test automation. Responsibilities include characterizing and troubleshooting RF measurement systems, developing and maintaining automated test and calibration software, and collaborating across hardware, software, and customer teams to ensure test equipment remains accurate and reliable at production scale.

Requirements

• Bachelor’s degree in Electrical Engineering or a related field.
• 3–4 years of hands-on experience in RF, wireless, or test/measurement engineering.
• Strong RF fundamentals and demonstrated ability to debug RF problems on the bench using standard RF test equipment, including signal generators, analyzers, VNAs, and power sensors.
• Proven experience developing automated test software from the ground up in Python and/or C++.
• Strong communication and interpersonal skills, including the ability to work directly with customers and present technical findings to engineering and cross-functional audiences.
• Willingness to travel internationally up to 15%.

Nice To Haves

• Master’s degree.
• Experience with RF system calibration methods, procedures, and traceability.
• Recent experience analyzing RF parameters in Python or MATLAB, including power, return loss, S-parameters, EVM, ACLR, IQ mismatch, and statistics.
• Working knowledge of DSP and communications theory.
• Familiarity with cellular (5G/4G), Wi-Fi, Bluetooth, mmWave, UWB, or NFC radio test and measurement.
• Familiarity with RF test equipment vendors such as Keysight, Rohde & Schwarz, NI, LitePoint, and Anritsu.
• CI/CD experience and a track record of integrating automated tests into a pipeline.
• Hands-on experience using AI assistants and agentic coding workflows to design, write, and debug production-level engineering software.
• Experience applying AI/ML techniques to RF data analysis, modeling, or anomaly detection.

Responsibilities

• Characterize and troubleshoot RF measurement systems on the bench.
• Develop and maintain automated test and calibration software.
• Partner with hardware, software, and customer teams to keep test equipment accurate and reliable at production scale.
• Collaborate with internal customers and present technical findings to engineering and cross-functional audiences.
• Support internal products from concept through mass production.
