Job description

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.

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 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 small, fast‑moving, and ambitious team building something truly transformative. At SBQuantum, you’ll have the opportunity to:

• Shape cutting‑edge quantum sensing technology from the ground up.
• Collaborate with passionate experts across physics, data science, and engineering.
• Contribute directly to solving real‑world challenges across critical industries.

Who We’re Looking For

We’re seeking a proactive and driven individual with experience in startups or the public safety sector to help us strengthen our software capabilities and shape the future of our technology. If you thrive in fast‑paced, multidisciplinary environments and love working on hard problems with real‑world impact, we’d love to meet you!

Be part of the next generation of quantum sensing and data‑driven innovation. Join SBQuantum and help us build the magnetic intelligence of tomorrow!

The Role

As a Senior Software Engineer, you will be one of the first engineering hires, working closely with the founding team. You’ll take ownership of backend development, implement algorithms grounded in complex physics, and integrate machine learning models into production systems. You’ll also play a key role in defining best practices, setting technical direction, and mentoring the engineers who join after you.

What You’ll Do

• Design, implement, and scale backend services that power our quantum sensor solutions.
• Translate complex physics algorithms into efficient, production‑ready software.
• Integrate and deploy machine learning models into real‑world applications.
• Collaborate with data scientists, physicists, and hardware engineers to bridge theory and practice.
• Work with our tech stack: Python, Native Android development, and AWS.
• Establish coding standards, testing frameworks, and DevOps practices to scale our systems.
• Help recruit, mentor, and grow the engineering team as we scale.

What We’re Looking For

• Technical Excellence: Strong backend engineering experience, ideally with Python, cloud platforms (AWS preferred), and distributed systems.
• Applied Science Mindset: Ability to understand and implement algorithms based on physics and scientific principles.
• Machine Learning Integration: Experience with deploying data science pipelines or ML models into production systems.
• Startup DNA: A self‑starter who thrives in early‑stage environments, comfortable wearing many hats, and excited about building from scratch.
• Collaboration: Strong communication skills and the ability to work closely with interdisciplinary teams (scientists, engineers, product).
• Leadership Potential: Desire and ability to help grow and mentor a team over time.
• Bilingual: Proficiency in French and English is an asset.

Nice‑to‑Haves

• Experience with scientific computing, numerical methods, or signal processing.
• Familiarity with Android native development.
• Background in working with sensor data, real‑time data processing, or IoT systems.
• Previous startup experience.

What We Offer

• Competitive salary and meaningful equity.
• Opportunity to be an early team member shaping both the technology and the culture.
• Flexible, collaborative work environment (remote/hybrid options).
• Direct impact: your work will shape breakthrough products in a cutting‑edge field.
• Professional growth opportunities as we scale.

At SBQ, we are mission driven and collaborate with people independently of gender, race, beliefs, citizenship, orientation and value unconventional paths. Let's meet!
