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 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

We’re a fast-growing deeptech startup building multiple bricks for the future of magnetic navigation. This is a unique opportunity to:

• 
  Pioneer magnetic navigation for real world applications


• 
  Bring your expertise in geophysics to collaborate with industry, government and contribute to an emerging product


• 
  Deploy and test your solution on different platforms


• 
  Have real ownership and impact in a high-growth, mission-driven environment

Who We’re Looking For

We’re looking for a proactive and 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 highly collaborative, able to work seamlessly across technical and non-technical teams and motivated by delivering meaningful impact through strong execution.

Key Responsibilities

• Magnetic field mapping & survey design - Plan and execute surveys to produce total-field, vector, and gradient magnetic maps for navigation applications, selecting appropriate sensor configurations, flight/traverse parameters, and tie-line strategies to meet required spatial resolution and coverage.


• Data processing & geophysical software - Process raw magnetic data through established workflows in Geosoft Oasis Montaj and equivalent geophysical toolchains, including diurnal correction, IGRF removal, levelling, microlevelling, gridding, and filtering


• Research-level modelling with SimPEG & Python - Apply open-source inversion and forward-modelling frameworks (SimPEG, discretize) alongside custom Python pipelines for advanced susceptibility modelling, potential field transforms, and algorithm development. Leverage these tools to simulate and compare different types of magnetic maps.


• Data QA - Continuously monitor and evaluate data quality throughout acquisition and processing; identifying noise sources, sensor anomalies, heading errors, and tie-line mismatches. Maintain rigorous QA/QC documentation to ensure map integrity for navigation use.


• Field trial coordination & adaptive survey management - Coordinate and lead field campaigns; liaising with platform operators, logistics teams, and navigation engineers; while interpreting data in real time and making informed decisions to adjust survey plans dynamically in response to coverage gaps or environmental conditions.


• Gridding, interpolation & map product delivery - Apply and evaluate gridding algorithms (minimum curvature, kriging, bi-directional) and potential field enhancements (RTP, upward continuation, derivatives) to produce calibrated, georeferenced map products formatted for direct ingestion into navigation systems.


• Cross-disciplinary collaboration & critical interpretation - Work closely with INS/navigation engineers to translate geophysical map outputs into fit-for-purpose navigation datasets, critically interpreting ambiguous magnetic signatures, flagging geological noise sources, and iterating on map specifications as system requirements evolve.

What We’re Looking For

• 
  5 years of experience in a startup environment


• 
  Background in magnetic map processing


• 
  Experience in autonomous platforms deployment


• 
  Comfortable wearing multiple hats and switching contexts quickly


• 
  Strong problem-solver with a bias toward action


• 
  Excellent communication skills (written and verbal)


• 
  Experience with Geosoft/MiraGeophysics/SimPeg and custom Python code

Nice-to-Haves

• 
  Experience in deeptech, hardware, or scientific environments


• 
  Familiarity with compliance, grants, or government processes


• 
  Bilingual English/French

What We Offer

• 
  Flexible hybrid work environment


• 
  Opportunity to shape both the company and its culture


• 
  Equity


• 
  Growth opportunities as SBQuantum scales
