We continuously push the boundaries of design and quality with a constant focus on providing high-performance solutions and value.

In our Ottawa design center, we create a wide range of products, including Home Theater Receivers, Audio and Video Processors, Single- Stereo- and Multichannel Amplifiers,Sound Distribution Systems and subwoofer pre-amplifiers and amplifiers sold under Anthem, Paradigm and MartinLogan brands. Each of our products is a masterpiece of engineering. We have expertise and capability to go through all stages of the product development, from in-house design to in-house manufacturing, from ideas and concepts to best products on the market that fuel the ambiance of living rooms and concert halls

Senior Embedded Firmware Developer:

We are looking for a Senior Embedded Firmware Engineer to take ownership of the control plane for our high-performance audio products. You will join a multidisciplinary team of hardware, software, and acoustic engineers to drive the "bare-metal" domain—developing and refining the safety-critical firmware that manages power sequencing, thermal protection, and inter-processor communication.

This is a hands-on role where you will join a strategic project in the middle of the development cycle, applying your expertise to help drive a flagship product to launch. Moving forward, you will have the opportunity to see product development through every phase, architecting solutions from ideation to mass production for our future roadmap. You will work side-by-side with our Hardware Engineers, using schematics and logic analyzers to debug complex interactions on custom circuit boards.

Key Responsibilities:

• Firmware Implementation: Develop, optimize, and maintain real-time C++ firmware for ARM Cortex-M microcontrollers (STM32/NXP i.MX) using FreeRTOS.
• System Lifecycle Ownership: Design and maintain custom Bootloaders for firmware updates.
• Collaborative Hardware Integration: Work closely with the Electronics team to bring up new boards. You will read digital schematics to verify pinouts and signal routing, enabling you to participate meaningfully in hardware/software debugging sessions.
• Low-Level Drivers: Write and refine drivers for complex peripherals (PMICs, Relays, ADC/DACs, Rotary Encoders) based on datasheets and active testing.
• Bus-Level Debugging: Troubleshoot communication failures on I2C, SPI, UART, and I2S buses. You should be comfortable hooking up a Logic Analyzer or Oscilloscope to verify timing and signal integrity alongside hardware colleagues.
• System Communication: Implement robust Inter-Processor Communication (IPC) protocols to exchange commands and file transfers with the Linux System on Module.
• Protection Logic: Design fail-safe algorithms for thermal management, short-circuit protection, and update recovery.

Experience and Qualifications:

• 5+ years of embedded firmware experience in C/C++.
• Experience with custom Bootloaders and Firmware Update mechanisms on bare-metal targets.
• Deep understanding of memory management (Flash layout, linker scripts, RAM execution).
• Hardware Literacy: Ability to read and navigate mixed-signal schematics.
• Lab Proficiency: Comfortable using Oscilloscopes, Logic Analyzers, and Multimeters to debug embedded systems.
• Deep understanding of communication protocols: USB, I2C, SPI, UART, and I2S.
• Solid understanding of RTOS concepts (Preemption, Queues, Mutexes).
• Experience with Git and collaborative development workflows (Jira).

HDMI Control Experience:

Knowledge of HDMI subsystems is a major asset. Specifically managing HDMI Matrix/Switch chips via I2C, handling Hot Plug Detect (HPD) events, parsing EDID structures, and implementing CEC state machines for system power control.
