As an Embedded 5G/4G Cellular Physical Layer Data Path Signal Processing Firmware Engineer, you will join a silicon design group focused on crafting and productizing powerful cellular SoCs. You will implement physical layer algorithms on digital and vector signal processors while interfacing with specialized cellular ASIC hardware to meet strict time, latency, memory, and energy constraints. Your daily work involves implementing 3GPP channels such as PDCCH and PDSCH, refining signal processing algorithms for efficient execution, and developing fixed-point firmware validated against algorithmic references. You will utilize C, C++, and Python while working with pre-silicon emulation systems and virtual platforms. The role addresses the technical challenge of delivering high-performance 4G/5G/6G multimode cellular firmware. Key competencies include a deep understanding of computer architecture, real-time operating systems, and wireless communication standards to solve complex signal processing problems in hardware-constrained environments.
Implement cellular physical layer algorithms on digital/vector signal processors with strict time, memory, and energy constraints.
Develop firmware to implement 3GPP channels and procedures such as PDCCH, PDSCH, PBCH, PUCCH, PUSCH, and PRACH.
Design and implement firmware architectures optimized for power, performance, and cost.
Analyze and implement fixed-point firmware while validating bit-exactness against algorithmic references.
Develop pre-silicon emulation systems and virtual platforms for verification purposes.
Create automation tools using Python for build processes, formal verification, and testing.
Refine signal processing algorithms in coordination with systems engineers for efficient hardware execution.
What we're looking for
A bachelor's degree is required.
Experience implementing digital signal processing algorithms using special purpose hardware or wireless physical layer channels via specialized hardware.
Deep understanding of software engineering principles and core computer science fundamentals.
Proficiency in C, C++, compilers, build tools, and source code control.
Experience with silicon prototyping, emulation systems, and virtual platforms.
Solid understanding of computer architecture, specifically high-speed communication subsystem HW/SW interfaces.
Experience with Python for developing automation tooling.
Familiarity with 3GPP cellular standards, RTOS, and machine learning concepts is preferred.
