Quantum Sensing Engineer Location: SherbrookeEmployment Type: Full time in a fast-growing startupAbout 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 technologies—like GPS, radar, imagery, or sonar—cannot 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 signals—turning 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 levelWork with a team to transition quickly NV physics into prototypesDeploy novel sensor designs on the field for end-user feedbackPioneer magnetic navigation for real world applicationsHave real ownership and impact in a high-growth,



mission-driven environmentWho We’re Looking For We’re 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. You’re 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 SWa P-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 We’re Looking For 4+ years of experience in a startup environmentBackground in experimental NV quantum sensing, from lab benches to devicesComfortable wearing multiple hats and switching contexts quicklyStrong problem-solver with a bias toward actionExcellent communication skills (written and verbal)Experience with quantum control pulse sequencesDemonstrated impact leading collaborative projects with academia collaboratorsNice-to-Haves Experience in deeptech, hardware, or scientific environmentsFamiliarity with compliance, grants, or government processesBilingual English/FrenchWhat We Offer EquityFlexible hybrid work environmentOpportunity to shape both the company and its cultureGrowth opportunities as SBQuantum scalesSBQuantum is based in Sherbrooke, Quebec — a hub of Quebec's growing quantum sector, where a trailhead, ski hill, or paddle-ready lake is still fifteen minutes from your desk.#J-18808-Ljbffr
