Principal L1 PHY and Modem Implementation Engineer

Quick Facts

• Role: Principal L1 PHY and Modem Implementation Engineer
• Focus: Hands-on development of L1 PHY and modem implementations for a high-throughput satellite communications system, from pre-silicon verification through system validation.

Description

Develop and optimize L1 PHY and modem implementations for high-throughput satellite communication systems. You’ll work across physical-layer processing, DSP implementation, HW/SW partitioning, and modem integration, translating communications and DSP algorithms into efficient production implementations. Collaborate with modem architecture, DSP algorithm, ASIC, FPGA, firmware, BSP, and system engineering teams from implementation and pre-silicon development through integration and validation.

Responsibilities

• Develop and optimize L1 PHY and modem implementations for high-throughput satellite communication systems.
• Implement and integrate PHY processing functions, including framing, FEC processing, rate matching, scrambling, modulation/demodulation, FFT/IFFT processing, reference-signal processing, and transmit/receive functions.
• Develop and optimize C/C++ (or equivalent) implementations of L1 PHY and DSP processing for embedded, real-time modem systems.
• Define and evaluate HW/SW partitioning of modem functions across CPUs/programmable processors, DSP engines, and FPGA/ASIC accelerators.
• Analyze and optimize modem processing for throughput, latency, computational complexity, memory bandwidth, data movement, and processor utilization.
• Optimize multicore processing, memory organization, buffering, concurrency, and accelerator utilization for high-throughput L1 processing.
• Work with modem algorithm engineers to translate communications and DSP algorithms into production implementations.
• Work with ASIC, FPGA, firmware, BSP, and system engineering teams to define and integrate interfaces between L1 software and modem hardware accelerators.
• Support pre-silicon verification, simulation, prototyping, system integration, and post-silicon validation.
• Debug complex system-level issues spanning L1 software, DSP processing, hardware accelerators, firmware, and ASIC interfaces.
• Evaluate modem architecture and implementation tradeoffs across performance, complexity, throughput, latency, memory, power, and hardware resources.
• Provide technical guidance and contribute to L1 PHY, HW/SW partitioning, and modem implementation architecture decisions.

Requirements

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical discipline.
• 10+ years of experience in L1 PHY software, modem implementation, DSP implementation, embedded communications software, or related areas.
• Strong understanding of OFDM-based communication systems and major transmit/receive PHY processing chains.
• Experience implementing or integrating L1 PHY processing on CPUs, DSPs, SoCs, FPGAs, ASIC accelerators, or heterogeneous processing architectures.
• Strong understanding of HW/SW partitioning and hardware acceleration of computationally intensive modem functions.
• Experience with performance profiling and optimization, multicore processing, memory management, and efficient data movement.
• Experience working with interfaces between L1 software, embedded firmware, and custom hardware or hardware accelerators.
• Ability to collaborate across modem, DSP, ASIC, FPGA, firmware, BSP, and system engineering teams.
