Quantum Sensing Engineer

Location: Sherbrooke
Employment Type: Full-Time in a fast-growing startup

About Us

SBQuantum is a seed-stage startup at the forefront of magnetic sensing innovation. Our vision is to unlock the full potential of magnetic intelligence through our proprietary quantum diamond technology and curated algorithms.

By combining diamond-based quantum sensors with advanced AI-driven software we transform complex magnetic field data into actionable high-value insights. Our solutions enable accurate magnetic mapping navigation and object detection in environments where traditional sensing technologieslike GPS radar imagery or sonarcannot perform.

From public safety and defence to space exploration our multidisciplinary team of engineers physicists and data scientists is redefining how the world perceives magnetic signalsturning invisible complexity into clear useful intelligence.

Why Join Us

SBQuantum is a fast-growing deeptech startup building multiple bricks for the future of magnetic navigation. At the heart of this emerging capability the diamond magnetometer vector compact and accurate readings are key to reach the full tech potential.

This is a unique opportunity to:

• Bring your expertise in quantum engineering and physics to push field deployable diamond magnetometry to next level
• Work with a team to transition quickly NV physics into prototypes
• Deploy novel sensor designs on the field for end-user feedback
• Pioneer magnetic navigation for real world applications
• Have real ownership and impact in a high-growth mission-driven environment

Who Were Looking For

Were looking for a proactive analytic yet hands-on person who thrives in building structure from the ground up and autonomous in making stuff happen. You bring a pragmatic solution-oriented approach with the autonomy and drive to move initiatives forward in a fast-paced environment. Youre combining your expertise in quantum control and prototyping with the team and collaborators to quickly transition bench demonstrations into product features.

Key Responsibilities

• Lead the development and experimental implementation of high-sensitivity operation schemes for NV-diamond magnetometers from concept through validated performance on hardware.
• Design implement and deliver novel quantum control and pulse-sequence protocols translating operation schemes into robust fieldable measurement routines and demonstrating quantifiable gains in sensitivity bandwidth and accuracy.
• Identify bottlenecks possible improvements to guide innovation and engineering.
• Define and execute SWaP-reduction work packages identifying the optical control and architectural changes needed.
• Contribute to optical design and sensor photonic integration leveraging your optics expertise to move from bulk/free-space setups toward integrated manufacturable sensor architectures.
• Own technical delivery of assigned R&D projects driving them against milestones technical targets and reporting commitments as the accountable performance lead.
• Champion the work both internally and with external partners coordinating collaborative work packages with academic and industry collaborators aligning shared deliverables and serving as the technical point of contact for the sensing effort.
• Share SBQuantum diamond magnetometry advancements at international technical workshops and events.

What Were Looking For

• 4 years of experience in a startup environment
• Background in experimental NV quantum sensing from lab benches to devices
• Comfortable wearing multiple hats and switching contexts quickly
• Strong problem-solver with a bias toward action
• Excellent communication skills (written and verbal)
• Experience with quantum control pulse sequences
• Demonstrated impact leading collaborative projects with academia collaborators

Nice-to-Haves

• Experience in deeptech hardware or scientific environments
• Familiarity with compliance grants or government processes
• Bilingual English/French

What We Offer

• Equity
• Flexible hybrid work environment
• Opportunity to shape both the company and its culture
• Growth opportunities as SBQuantum scales

SBQuantum is based in Sherbrooke Quebec a hub of Quebecs growing quantum sector where a trailhead ski hill or paddle-ready lake is still fifteen minutes from your desk.
