  • PHY Systems Engineer Simulations

    Boston,Massachusetts,United States


    • Deep knowledge of communication system theory and PHY signal processing

    • Validated track-record in SW and simulator design in C++, including experience with simulator frameworks and configuration management.

    • In-depth knowledge of wireless communication systems with hands-on experience in 4G/5G PHY design, pre-silicon verification and critical metric testing

    • Experience with Matlab, C++ and/or Python programming including substantial knowledge of algorithms and data structures, memory and runtime profiling as well as code optimization techniques.

    • Solid knowledge of current cellular communication standards: 5G (NR) and 4G (LTE).

    • Experience in chip bring-up including the use of lab equipment is a plus

    • Strong analytical and problem-solving skills (linear algebra, random processes, estimation and detection, debugging and fixing of defects, ...).


    You will take part in the pioneering work of creating and developing innovative PHY algorithms and simulation models 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 modelling, meaningful metric testing and framework design. - Design PHY test cases for new features and drive bring-up and issue resolution. - Integrate PHY reference models in PHY only, reduced signaling and full stack pre-silicon simulation and verification environments in close cooperation with our HW and FW design teams - Perform research activities and requirements management to anticipate the impact on algorithms, configuration and scheduling according to the latest 3GPP standards - Actively contribute to software architecture and design for existing and future PHY projects - 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
