DSP Designer

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

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

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)

This role is being posted to fill an existing vacancy.

We also recognize that candidates show interest throughout different career stages and welcome all applications. When there is a great fit, the level of the role may be shifted as applicable.

Since 2001, Fidus has completed over 4,000 projects for more than 400 customers across industries including Telecom/Datacom, Aerospace & Defence, Consumer, Semiconductors, Industrial/Automotive Controls, and Medical. As a Premier Adaptive Computing Partner for AMD North America, we combine deep technical expertise with industry-leading tools to solve complex design challenges.

Fidus designs high-speed, high-complexity electronic systems using emerging technologies, often well before they reach the broader market. Our teams work across FPGA/DSP, hardware, embedded software, verification, SI/PI, PCB layout, and mechanical/thermal design to deliver real products for our customers.

Our work spans space and satellite systems, next-generation communications and networking, high-performance compute and storage platforms, advanced video and imaging, and industrial, medical, and automotive systems. We are not tied to a single product or industry—our work follows the technology, not just one roadmap.

At Fidus, collaboration is at the core of how we work. We value openness, trust, and shared ownership, and we create an environment where people are encouraged to contribute ideas, learn from one another, and have a meaningful impact through the work they do.

If all of this excites you, has your attention, and you can't wait to join our amazing team and work environment, then we want to hear from you!

Fidus has a commitment to ensure a fair and transparent recruitment process. Automated tools (including AI) support our initial screening of applicants against our job posting to identify candidates whose qualifications, experience, and skills align most closely with the position requirements. All further candidate assessments and final selection are conducted by our human recruitment team. AI does not make any final hiring decisions.

Thank you for your interest in Fidus. We welcome and encourage diverse candidates to apply. Accommodations are available upon request for candidates taking part in all aspects of the selection process. Fidus is committed to creating a diverse environment and is proud to be an equal opportunity employer.
