Role summary
Apple is seeking a Cellular Software Architect/Developer with expertise in wireless technologies and ecosystems. This role involves designing, developing, and maintaining network simulations for 4G/5G cellular protocols, focusing on RRC, MAC, and PHY layers. The ideal candidate will have a strong understanding of protocol procedures and network interactions, with experience in C, C++, and scripting languages. Experience with test basestation and RAN/CN network emulators is essential. Preferred qualifications include Python, shell scripting, and experience in simulation environment development or test case scripting. A degree in Electrical Engineering, Computer Engineering, Computer Science, or equivalent is required.
Description
This role requires critical expertise in multiple layers of cellular protocols. Experience with UE and/or network protocol development for 4G/5G technologies is essential. The candidate must demonstrate a solid understanding of relevant protocol procedures and network interactions. The duties of this position will include designing, developing, and maintaining network simulations. The candidate will need to understand the 4G/5G protocol functionality in the respective 3GPP releases and convert that knowledge into corresponding protocol implementations and interfaces in the cellular network simulation system domain.
Minimum Qualifications
Bachelor’s or graduate degree in Electrical Engineering, Computer Engineering, Computer Science or equivalent degree. Excellent knowledge of 4G/5G protocol stack and procedures, especially in RRC, MAC, and PHY layers. Working knowledge of implementing test basestation and RAN/CN network emulators (Keysight, R&S, Anritsu, Anite, etc.). Excellent software development and debugging skills, including design, programming (C, C++, scripting).
Preferred Qualifications
Strong experience in shell scripting and Python. Strong experience in cellular protocol stack host test or simulation environment development is key. Experience in test case scripting and debugging regression test suites conforming to relevant ETSI/3GPP protocol technical specifications is a big plus. GenAI design and coding experience is a plus. Standard software development & tool environments is a plus. Highly motivated and self-directed, fast learner, a good team player. Excellent verbal and written communication skills.
