Embedded Firmware Engineer

Location: Ottawa, ON (on-site) Employment type: Full-time Salary range: $95,000 – $130,000 CAD per year About Q-Block Computing: Q-Block Computing builds quantum systems that operate in the real world. The company develops quantum timing, quantum-secure communications, and quantum computing platforms engineered for the performance, reliability, and environmental resilience that mission-critical applications demand — systems designed to be deployed, maintained, and trusted by operators who cannot afford ambiguity about whether the technology works. The long-term vision is deeper than any single platform.

Q-Block is pursuing a mission to decode Nature's foundational model — to build instruments of sufficient precision and coherence that they become tools for understanding the physical universe at its most fundamental level. Every system engineered to sustain quantum coherence under real-world conditions is also an advance in what becomes scientifically possible next. Commercialization and science reinforce each other by design.

About this role: The Embedded Firmware Engineer will develop the real-time control firmware that sits at the heart of Q-Block's quantum hardware platforms — the code that turns precision electronics into coordinated, deterministic, trustworthy instruments. The work spans peripheral drivers, DMA and interrupt architectures, digital control loops, and multi-unit synchronization, all on ARM Cortex-M-based platforms designed to be built, qualified, and deplo
