Principal DSP Firmware Engineer

Ottawa, ON – Córdoba, Argentina - Irvine, CA

About the Role

 

We are seeking Principal DSP Firmware Engineer to lead the architecture, development, and validation of firmware supporting advanced DSP algorithms on next‑generation silicon platforms. You will play a critical role in defining DSP firmware strategy, owning pre‑silicon development, and leading silicon bring‑up, while mentoring engineers across the team.

This role is ideal for a senior technologist who can own end‑to‑end DSP firmware subsystems and drive technical decisions from architecture through deployment.

Locations Available: Ottawa, ON – Córdoba, Argentina – Irvine, CA

Key Responsibilities:

  • Lead the architecture, design, and implementation of DSP firmware subsystems
  • Define FW control interfaces, configuration parameters, and runtime debug controls and diagnostics
  • Drive collaboration with system architects and DSP designers on algorithm partitioning, FSM design, and firmware controls
    • Design finite state machines governing DSP acquisition and tracking control loops
    • Optimize firmware for real‑time operation, latency, throughput, and resource usage to meet FW 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
  • Drive regression strategy, automation, and test reusability, including customer release automation using Jenkins pipelines
  • Debug complex firmware, DSP, and system‑level issues
  • Own bring-up of DSP acquisition flows
  • 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.
  • 6–10 years of experience in embedded/firmware development.
  • Strong background in DSP theory and algorithm implementation
  • Optimizing FFT algorithms and FFT‑based resampling (preferably on SiFive processors)
  • Deep experience architecting DSP‑centric firmware systems and expert‑level programming skills in C/C++
  • Familiar with emulation testing frameworks and firmware‑level mocking strategies
  • Experience with pre‑silicon development, silicon bring‑up, and system‑level debugging
  • Familiar with UVM based verification environments and SystemVerilog test methodologies
  • Familiar with FPGA and emulation platforms for pre silicon validation
  • Experience with silicon bring-up, board bring-up, and complex firmware debugging.
  • Ability to work cross‑functionally with systems, DSP, verification, and hardware teams
  • Strong technical leadership and mentoring skills

Preferred Qualifications

  • Knowledge of
    • CMIS (Common Management Interface Specification) standards for optical modules
    • RISC V architecture (SiFive or similar)
  • Familiarity with
    • Operating environments: Embedded Linux or RTOS (FreeRTOS, Zephyr, VxWorks)
    • Boot architecture: U‑Boot, custom multi‑stage boot flows
    • Low‑level SoC and hardware interfaces: PCIe, Ethernet, I2C, SPI, UART

 

Salary Range for US 

$150,000 - $250,000 Base Annually 
The final offer will be determined based on job-related skills, experience, qualifications, and location.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Form CC-305

OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
