Digital-Analog Electrical Engineer

Location: Ottawa, ON (on-site) Employment type: Full-time Salary range: $70,000 – $125,000 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 Digital–Analog Electrical Engineer will contribute to the development of massively scalable, real-time digital–analog control electronics at the heart of Q-Block's quantum platforms. The work centers on hybrid circuits where high-fidelity analog performance and deterministic digital control must coexist on the same board, under the same timing discipline, at the noise floor quantum hardware requires. This is hands-on electronics engineering for systems that are meant to be built, qualified, and deployed — not one-off laboratory prototypes. The successful candidate is an electrical engineer who is genuinely at home at the boundary between analog and digital, comfortable moving between schematic capture, SPICE simulation, PCB layout, firmware-facing interfaces, and the oscilloscope on the bench. The role rewards engineers who have learned their craft in domains where precision, synchronization, and low-noise performance are non-negotiable, whether that lineage comes from scientific instrumentation, large experimental facilities, sensor-intensive platforms, or any environment where many channels of data must be acquired, synchronized, and trusted. Responsibilities Design, implement, and validate hybrid digital–analog PCBs for quantum hardware used in sensing, communication, and computation platforms. Translate board-level requirements into design concepts: architecture, I/O, signal integrity plan, power tree, thermal budget, key part selection, and firmware interface definition. Design and integrate precision analog front-ends, high-speed DAC and ADC subsystems, low-noise reference and biasing circuits, and the conditioning electronics that connect them to real-world quantum hardware. Architect digital control paths around MCUs and FPGAs with emphasis on deterministic, low-latency behavior and clean coexistence with sensitive analog subsystems.
