About the role

The Senior Quantum Engineer will serve as a technical leader in Q-Block's R&D engineering organization, with responsibility for driving the development, integration, and productization of quantum hardware systems from prototype to deployed capability.
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.

specification, design, build, test, and documentation through the full development cycle.
The Senior Quantum Engineer will own engineering decisions within their domain, mentor junior engineers, and operate as a bridge between experimental capability and 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.
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.
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.
These are systems designed to be deployed, maintained, and trusted.

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.
Experience in a productization or reliability engineering context: transitioning prototype hardware to robust, repeatable, fielded systems.

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.
Security and Compliance Requirements 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.

$120,000-$160,000 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.
These are systems designed to be deployed, maintained, and trusted.
Every system engineered to sustain quantum coherence under real-world conditions is also an advance in what becomes scientifically possible next.
The commercialization and the science reinforce each other by design.
