Key Qualifications

  • The ideal candidate has 5+ years of experience in specifying and implementing features on wireless device platforms through to successful integration and product launch.
  • The candidate’s experience should demonstrate a proven track record in software/systems design and performance tradeoffs in consumer products.
  • Expertise with wireless chipset platforms (such as details of WiFi and/or NR control and data plane, RF transceivers), system integration topics such as platform operational modes, link adaptation, RF front-end control and in-device coexistence.
  • Expertise in modeling end to end performance of wireless systems to optimize critical performance metrics (such as link adaptation performance, throughput optimization, surround cell/scan operations, edge of cell coverage issues).
  • Deep understanding of wireless communication platforms and modem requirements and use cases at both the network and the consumer product level. This should ideally cover different standards such as WiFi and LTE/5G NR.
  • Strong knowledge of 3GPP standards (LTE, NR), WiFi, BT and similar wireless technologies with an emphasis on the lower layers such as MAC, Layer1
  • Experience in leading cross-functional teams by technical expertise and bringing solutions together for new products in particular for the consumer device market is important.
  • Ability to present complex technical topics to a multi-level audience both internal and external to Apple.
  • Strong communication skills, proficient programming skills in C++ and/or modeling complex systems in MATLAB desirable.


In this role, you will Identify and drive innovation for wireless systems with focus on enhancing end-user experience when multiple wireless standards are active concurrently. The work requires you to participate in a small dynamic team to define and specify wireless systems performance optimization, with a focus on integration of multiple technologies and how they should interact in a complex consumer product environment. The expectation is to analyze, model and optimize different wireless configurations and usage scenarios for the best performance in challenging environments to support the design teams. Create and participate to then drive SW and system architectures as a result of this work in a cross-functional team of domain experts to optimize cross-technology performance and in-device coexistence across a portfolio of products. There will be ample opportunity due to the novel nature of the work to create intellectual property and technical specifications.
