About The Position

Are you an innovative thinker? Do you love the challenge of advancing a widely
accepted technology? The Wireless Technologies and Ecosystems (WTE) team is
seeking a hardworking individual with outstanding communication skills and an
exceptional technical knowledge of cellular technologies. You will design,
develop the next generation of our innovative connectivity technologies. You
will be responsible for delivering architecture, design and implementation of
multi-layers, distributed, and real-time simulation componentsYou will
collaborate across departments to help craft wireless solutions that elevate the
customer experience with Apple products and iOS SW features.

DESCRIPTION

We are working on influencing the definition of next-generation wireless
systems/standards in terms of system concepts and network architecture. You will
have the opportunity to work with different technical teams to define wireless
and network features and help drive external infrastructure vendors and carriers
to full feature realization. While partnering with other engineers you will
define problem statements, design AI/ML-based data-driven learning solutions,
assess the system-level performance, and research innovative ideas & solutions.
Most importantly, you will be part of building/contributing to our
simulator/emulator framework. You will be focussing on designing and developing
complete SW components embedded into the simulation to verify end-to-end various
items/ideas/concepts. Day to day, you will define innovations and technical
contributions in different areas of the cellular system (L1/L2/L3) and network
architecture. You will build physically accurate ray tracing algorithms and
engines for AI/ML integration with wireless simulations as well as rendering
these same environments into real-time 3D visualizations. You will design,
develop, integrate and bringup simulation components/subsystems with their
corresponding infra-structure (e.g.; message passing, event-triggering, etc) to
model cellular technology. In addition, you will contribute in defining services
and functionalities delivered by the simulator, profiling and optimizing code.
Moreover, you will develop models of overall system and network performance and
evaluate performance and critical metrics tradeoffs to optimize the overall
architecture. This is an extraordinary opportunity to help Apple build
innovative wireless devices and features for hundreds of millions of Apple
users. If you are passionate about shaping the future of connectivity, we would
love to hear from you!
