Position Overview/Mandate:The DSP Designer plays a key role in developing and delivering complex signal processing algorithms for Fidus clients, from concept through simulation, fixed-point implementation, and hardware bring-up. You will work directly with customers and internal Fidus FPGA/hardware teams to design algorithms, perform quantization and bit-width analysis, and translate DSP concepts into feasible hardware architectures.
This role is ideal for someone who enjoys moving between application domains (communications, radar/sensing, industrial, medical), is comfortable working across the algorithm-to-hardware boundary, and takes pride in producing well-documented, bit-true designs.
What You'll Be Doing:- Develop and simulate DSP algorithms (equalization, filtering, estimation, detection) in MATLAB/Simulink and/or Python, from concept through fixed-point validation
- Perform quantization/bit-width analysis and produce bit-true fixed-point models suitable for HDL implementation
- Collaborate with FPGA/HDL and hardware teams to translate algorithms into feasible hardware architectures (pipelining, MAC/resource budgeting, timing closure)
- Support HDL verification through golden-model test vectors and co-simulation
- Support lab bring-up, characterization, and tuning of DSP-based hardware against real-world channel/sensor behavior
- Adapt existing DSP toolkits to new client domains and standards across multiple engagements (e.g., communications, Aerospace & Defense, Space & Satellite, Industrial Automation, Automotive, Medical Devices, and Semiconductor)
- Document algorithm design decisions, trade-offs, and validation results for client and internal reference
Who You are:- BS/MS/PhD in Electrical Engineering, Applied Physics, or related field
- Strong foundation in signals and systems: Fourier/Z-transform, digital filter design (FIR/IIR), sampling theory
- Practical experience with estimation/detection theory (e.g., matched filtering, MMSE, Kalman filtering) or adaptive filtering (LMS/RLS)
- Proficiency in MATLAB/Simulink and/or Python for algorithm design and simulation
- Experience with fixed-point conversion and quantization trade-off analysis
- Demonstrated ability to work across the algorithm-to-hardware boundary (collaborating directly with HDL/FPGA teams)
- Strong verbal and written communication skills - ability to explain algorithm trade-offs to non-DSP stakeholders
Nice to Have:- Experience in one or more of: optical/wireless communications, radar/sensing, motor control, biomedical signal processing, semiconductor test
- Experience with high-speed SerDes and PAM4 signaling (e.g., PCIe Gen6, 400G/800G Ethernet electrical) - equalization (FFE/CTLE/DFE), link training, and FEC awareness
- Familiarity with AMD's Adaptive Computing portfolio (Versal, Alveo) or embedded x86 product lines
- Familiarity with HDL Coder, HLS, or Simulink-to-HDL co-simulation workflows
- Hands-on lab experience (scope, VNA, BERT, or domain-equivalent test equipment)
- Exposure to safety-critical or regulated development processes (DO-178C/DO-254, ISO 26262, IEC 62304/60601) - valued for A&D, automotive, and medtech engagements specifically
- Experience adapting quickly across multiple industries or client domains (consulting/services background a plus)
- Exposure to AI/ML techniques applied to signal processing on FPGAs, GPUs, NPUs, or CPUs
- Experience with dedicated DSP processors (e.g., Analog Devices, Texas Instruments)
- Experience with RF front-end systems and data converter interfaces (ADC/DAC), including digital up/down-conversion (DUC/DDC)
