Digital-Analog Electrical Engineer

• 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.
• Design clock distribution, synchronization, and timing reference circuitry for coherent multi-channel and multi-board operation.
• Apply RF design discipline where needed: controlled-impedance routing, shielding strategy, grounding, and EMI/EMC considerations appropriate to precision mixed-signal systems.
• Complete schematic capture, manage layout constraints and placement, lead layout reviews, and produce manufacturing and assembly documentation.
• Own BOM, part qualification, long-lead-item management, and design-for-manufacturability decisions.
• Perform SPICE and signal-integrity simulation, noise and stability analysis, and other pre-silicon and pre-layout design analyses to retire risk before fabrication.
• Plan and execute bring-up, characterization, and validation on the bench using oscilloscopes, network and spectrum analyzers, arbitrary waveform generators, and custom test fixtures.
• Identify technology and design risks early and drive them to closure with clear, documented reasoning.
• Collaborate across hardware, firmware, optics, and systems teams; contribute to a culture of continuous learning, rigorous design review, and honest technical discussion.

• Bachelor's degree in Electrical Engineering, Computer Engineering, Engineering Physics, Physics, or a closely related field.
• 5+ years of professional experience designing digital, analog, and mixed-signal circuits, with demonstrated ownership of boards taken from concept through validated hardware.
• Extensive understanding of electronic circuit design, communication protocols, and PCB design and manufacturing processes.
• Strong laboratory skills with oscilloscopes, network and spectrum analyzers, arbitrary waveform generators, and standard bench instrumentation for characterizing precision electronics.
• Proficiency with SPICE simulation and standard mixed-signal design analysis techniques.

• Demonstrated experience with RF design, low-noise analog circuit design, or high-speed signal paths.
• Hands-on experience with precision DAC/ADC subsystems, low-noise references, and analog front-ends for sensitive measurement or control.
• MCU- and FPGA-based digital control design, including deterministic, low-latency control architectures on hybrid digital–analog boards.
• Experience with clock distribution, multi-channel synchronization, and timing-critical data acquisition across distributed hardware.
• Background in environments where large arrays of channels must be acquired, synchronized, fused, or controlled with tight timing discipline — across scientific, experimental, or defense-adjacent domains.
• Exposure to signal processing, noise analysis, and systems where the analog performance floor directly determines scientific or operational outcomes.

• Must be eligible to obtain and maintain Government of Canada security clearance, if required for assigned projects.
• Must be eligible to comply with requirements of the Controlled Goods Program, if required for assigned projects.
• Must be willing to participate in background screening, documentation, and compliance processes associated with security-sensitive work.
• Ability to work effectively within security, export-control, and compliance-sensitive technical environments is an asset.

• Strong attention to detail, authenticity, and a sense of responsibility in all tasks.
• Critical thinking and a problem-solving mindset grounded in measurement and evidence.
• Clear written and verbal communication; ability to produce design documentation that holds up under rigorous review.
• Strong interpersonal skills and the ability to work collaboratively in a dynamic, multidisciplinary team.
