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
Required Qualifications
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
Salary Range $150,000 - $250,000 Base Annually
The final offer will be determined based on job-related skills, experience, qualifications, and location.
Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field.
