Senior DSP Firmware Engineer

About the Role:

We are seeking a Senior DSP Firmware Engineer to design, implement, and debug firmware supporting advanced DSP algorithms on next‑generation silicon platforms. You will work closely with system architects, DSP designers, and verification teams to deliver high‑performance firmware across pre‑silicon and post‑silicon environments.

This role is ideal for a hands‑on engineer with strong DSP fundamentals who can accelerate development, own defined subsystems, and contribute to mentoring junior engineers.

Locations Available: Irvine, Ottawa Ontario, Argentina

Key Responsibilities:

• Design, implement, and maintain firmware supporting advanced DSP algorithms on embedded processors, working closely with system designers on

• Design finite state machines governing DSP acquisition and tracking control loops


• Optimize firmware for real‑time operation, latency, throughput, and resource usage to meet firmware specifications

• Own pre‑silicon test‑driven development framework for DSP firmware

• Hardware Abstraction Layer generation and integration with simulation, emulation platforms


• Collaborate with verification teams to align firmware validation strategy with regression infrastructure

• Debug complex firmware, DSP, and system‑level issues

• Analyze issues using firmware logs, traces, and instrumentation


• Support regression testing teams by identifying root causes and improving test coverage

• Enforce firmware coding standards, test coverage and best practices

• Mentor and guide junior firmware engineers


• Contribute to defining development workflows, and long‑term maintainability

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field.


• 3–5 years of relevant experience in embedded/firmware development


• Strong background in Digital Signal Processing (DSP) fundamentals and algorithm implementation

• Optimizing FFT algorithms and FFT‑based resampling (preferably on SiFive processors)

• Strong hands-on expertise in:




• Programming: C/C++


• Firmware development: for DSP‑centric embedded systems


• Debug and analysis tools: tracing, profiling, logging, and hardware/software debuggability

• Ability to work cross‑functionally with systems, DSP, verification, and hardware teams


• Strong communication skills and ability to mentor junior engineers

Preferred Qualifications

• Experience working in coherent optical systems, silicon photonics


• Knowledge of RISC V architecture (SiFive or similar)


• Familiarity with:
  
  
  
  • FPGA and emulation platforms for pre silicon validation
  
  
  • Lab bring up tools, including JTAG debuggers, logic analyzers, and oscilloscopes
  
  
  • UVM based verification environments and SystemVerilog test methodologies
