Description
You will take part in the pioneering work of creating and developing simulation models for innovative PHY signal processing and control algorithms which enable cellular modem system design and verification for very high-data rate applications. Your responsibilities will include but are not limited to:- Design and implement 4G/5G PHY models for pre-silicon simulation and verification.- Perform functional and performance verification of the PHY models using internal and 3rd Party test tools as well as test data provided by external network vendors.- Contribute to link-level simulator modeling, meaningful metric testing and Base Station Model architecture and design.- Define PHY test cases for new features and drive bring-up and issue resolution.- Design and develop robust multi-threaded algorithms with hard real-time constraints, leveraging multi-core processors.- Perform real-time profiling and optimization, including necessary redesign of existing implementations.- Collaborate across functional teams to define and document project requirements, concepts, model architecture, interfaces and APIs.- Contribute to simulator configuration management and perform SW releases.
Minimum Qualifications
- Validated track-record in SW and simulator design in C++, including experience with simulator frameworks and configuration management.
- In-depth knowledge of Embedded SW Development, including concurrency and parallelism concepts (e.g. threads, semaphores and other synchronization mechanisms).
- Solid knowledge of multi-core processor architectures, multi-threading, inter-process(or) communication, efficient implementation of parallel algorithms and performance optimization techniques.
- Experience with C/C++ and/or Python programming including significant knowledge of algorithms and data structures, memory and runtime profiling.
- Strong analytical and problem-solving skills (linear algebra, random processes, estimation and detection, debugging and fixing of defects, …).
Preferred Qualifications
- Good understanding of communications systems theory and PHY signal processing.
- Experience with 4G/5G PHY design is a plus as well as experience in system and/or link-level simulation, pre-silicon verification, chip bring-up and the use of lab test equipment.
- Experience with software refactoring including requirements management, design, implementation and verification.
- MS in Computer Science or Electrical/Information Engineering with 8+ years of working experience or PhD in relevant field with 5+ years of working experience.
- Apple is an Equal Opportunity Employer that is committed to inclusion and diversity. We also take affirmative action to offer employment and advancement opportunities to all applicants, including minorities, women, protected veterans, and individuals with disabilities.
