Senior Embedded Linux Developer; Audio Platforms

Position Title: Senior Embedded Linux Developer (Audio Platforms)

Location: Ottawa, ON

Department: R&D

Status: Full-time, permanent

Salary Range: $110,000 to $145,000 CAD

About us:

For over forty years our companies, industry-leading manufacturers and distributors of high-quality, luxury consumer audio products, have set the standard for excellence in every product category we offer. 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 Martin Logan 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!

We are looking for a Senior Embedded Linux Developer to engineer, maintain, and optimize the core Linux foundation for our next-generation streaming audio products. You will assume responsibility for the Board Support Package (BSP), the kernel, and the low-level audio pipeline.

This is a highly technical, hands-on role where you will join a strategic project in active development. You will work directly with our System Architects to stabilize and optimize the underlying "plumbing"—from the I2S clocks on the circuit board to the ALSA drivers and Pipe Wire graph—ensuring our flagship products meet the high standards of our brand. As you drive the current product to launch, you will play a key role in defining the OS strategy and tooling for our future product roadmap.

Key Responsibilities:

• Platform Ownership: Maintain, customize, and optimize the Yocto-based Linux distribution for NXP i.MX and similar SoCs. You will manage Bit Bake recipes, layers, device tree overlays, and secure boot configurations.
• Audio Subsystem Integration: Dive deep into the Linux audio stack. You will configure ALSA System-on-Chip (ASoC) drivers, debug DAI links (I2S/TDM), and ensure userspace routing using Pipe Wire and Wire Plumber is robust and glitch-free.
• Vendor SDK Integration: You will be the expert at merging complex vendor SDKs (e.g., Stream Unlimited, NXP) with our custom codebase. You will handle kernel upgrades, resolve upstream conflicts, and patch drivers to support our specific use cases.
• Hardware Bring-up: Work side-by-side with Electrical Engineers to validate new boards. Use logic analyzers and oscilloscopes to verify clocks, digital interfaces, and driver initialization sequences.
• System Reliability & Performance: Act as the lead debugger for complex system failures. You will use tracing tools such as ftrace, perf, Wireshark, and LTTng to root-cause latency issues, eliminate XRUNs (audio dropouts), and optimize boot time and power consumption.

Experience and Qualifications:

• 5+ years of Embedded Linux development experience, with substantial experience in audio or multimedia systems.
• Linux Audio Deep Dive: Expert knowledge of ALSA System-on-Chip (ASoC). You must be comfortable configuring asound.conf, writing or patching machine drivers, debugging DAI links (I2S/TDM), and troubleshooting clock synchronization issues.
• Multimedia Frameworks: Strong experience with GStreamer and/or Pipe Wire. You understand how to construct and debug complex graphs, manage buffer negotiation, and integrate proprietary plugins such as NXP-optimized components into the pipeline.
• Proprietary Stack Integration: Proven experience…
