Job Level
About the role
- Lead the architecture, design, and validation of high-speed serial transceivers across electrical and optical domains
- Leverage expertise in systems engineering, control theory, DSP algorithms, and modeling to develop cutting-edge serial electrical/optical-IMDD transceiver solutions
- Perform system-level evaluation, modeling, and performance analysis of SerDes transceiver solutions including impairments and mitigation techniques
- Develop algorithms and architectures for adaptive equalization, maximum likelihood sequence detection (MLSD), and timing recovery algorithms
- Integrate control theory and advanced DSP designs into feasible hardware implementations
- Collaborate with cross-functional teams (analog design, ASIC design, electro-optical hardware, firmware) to optimize SerDes performance in end-to-end systems
- Conduct design trade-offs to meet stringent performance, power, and area targets
- Analyze channel models, analog circuits impairments (DAC, ADC, AFE, …) and system constraints to determine system level margin and FEC (forward error correction) performance and optimize system margin
- Document design specifications, system performance results, and contribute to IP generation and innovation roadmaps
Requirements
- Advanced expertise in electrical SerDes DSP design and implementation
- Proven experience in SerDes system-level evaluation, modeling, and simulation
- Strong proficiency in control theory and digital signal processing (DSP) applied to high-speed communication systems
- Familiarity with optical IMDD (Intensity Modulation Direct Detection) systems
- Deep understanding of adaptive equalization techniques for high-speed links
- Proficiency with maximum likelihood sequence detection (MLSD) approaches
- Expertise in timing recovery schemes in high-speed serial links
- Practical knowledge of FEC performance modeling and system-level performance optimization
- Experience with MATLAB, Python, or C/C++ for algorithm design and simulation
- Strong problem-solving skills and ability to work across hardware/software boundaries
- Ph.D. in Electrical Engineering with background in digital communications and signal processing
- 8+ years of experience in high-speed serial link or communication system design
