Senior Quantum Engineer

• Lead the engineering design, integration, and qualification of quantum hardware subsystems — optical, photonic, electronic, control, and mechanical — across Q-Block's platform programs, from prototype through field-deployable system.
• Own subsystem-level performance: define specifications, plan verification and validation campaigns, analyze failure modes, and drive technical closure on engineering issues with clear, documented reasoning.
• Drive productization and design-for-reliability efforts, including ruggedization, thermal management, environmental qualification, and manufacturing-readiness transitions for quantum system components.
• Develop and improve fabrication, assembly, alignment, and calibration procedures for precision optical and electronic subsystems, with attention to repeatability, yield, and operator-independent performance.
• Collaborate with scientists and systems architects to translate performance requirements and physical constraints into engineering design specifications.
• Lead design reviews, establish engineering standards and documentation practices, and provide technical mentorship to junior engineers on the team.
• Identify and retire technical risks proactively; lead root-cause analysis for subsystem failures and implement robust corrective actions.
• Contribute to technical proposals, engineering documentation, and IP capture processes as appropriate.
• Stay current with developments in quantum hardware, photonics, precision electronics, and related engineering domains.

• PhD degree in Engineering Physics, Electrical Engineering, Photonics, Mechanical Engineering, or a closely related field.
• 5+ years of professional engineering experience in quantum hardware, scientific instrumentation, photonics, precision electronics, or a related deep-tech hardware domain.
• Demonstrated ownership of subsystem-level engineering deliverables: specification, design, build, test, and documentation through the full development cycle.
• Strong hands-on capability in at least one of: optical systems engineering, laser hardware and stabilization, photonic integration, precision analog electronics, or quantum control systems.
• Experience in a productization or reliability engineering context: transitioning prototype hardware to robust, repeatable, fielded systems.
• Clear, disciplined technical communication: architecture documents, verification plans, test reports, and engineering specifications written for a demanding technical audience.

• Hands-on experience with one or more of: UHV systems, neutral-atom or ion trap hardware, optical frequency metrology, fiber-optic network components, quantum key distribution hardware, or FPGA-based real-time control.
• Experience with precision timing systems, synchronization architectures, or PNT-related hardware.
• Track record of system-level integration across optics, electronics, and software in a quantum or precision instrumentation context.
• Experience working in or alongside defense, national security, or high-assurance systems environments.
• Familiarity with relevant standards and compliance frameworks for defense or regulated hardware programs.

• 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.
