We are now building the navigation solution on top of them, and we want someone who has done it before to lead that work. You will own inertial navigation and sensor fusion end to end: the estimation architecture, the algorithms, the calibration, the validation and the roadmap. You will set the technical direction for fusion and INS development and grow a small team around it, working directly with the CEO and the gyro design team. This is a hands-on lead role, not a management role. Navigation architecture. The INS mechanization and the GNSS/INS estimation architecture, and the reasoning behind every design choice in it. IMU error models, factory and in-field calibration, temperature compensation, and the test regime that proves them out. Performance and validation. Define how we measure navigation performance, run truth-referenced test campaigns, and own the numbers we publish. Set the fusion and INS roadmap with product leadership, then grow and lead the navigation software team behind it. Customer depth. Support integration at demanding customers and hold your own in the room with their navigation engineers. Substantial hands-on experience building GNSS/INS or inertial navigation systems that actually shipped, flew, drove or dived. Deep working knowledge of inertial navigation: strapdown mechanization, coordinate frames, error propagation, alignment. Kalman filtering on real data, tuning, observability, fault detection,



and knowing why the filter diverged at minute 40. GNSS fluency, including RTK or PPP, and a realistic view of how GNSS degrades in the environments our customers operate in. Production-quality C or C++ on embedded targets, plus Python or MATLAB for analysis. Comfort with the unglamorous half of the job: logging, replay, regression, bench and field test. Sleeves-up in a startup: we are small, and everyone helps with whatever the team needs. Eligible to work in Canada and to be cleared for controlled-goods and export-controlled work. Fiber-optic, ring-laser or another high-performance gyro class in your background, rather than MEMS only. Experience leading or growing a small technical team. Graduate research in navigation, and a track record in the ION community. Bilingual, French and English. Relocation support is available for this position. One Silicon Chip Photonics (OSCP — legal entity OSCPS Motion Sensing Inc.) develops next-generation photonic inertial measurement units (IMUs) and navigation systems for GNSS-denied environments. We are Montréal-based, venture-backed, and ITAR-free (Canadian jurisdiction) — a deliberate strategic advantage for our customers. Self-motivation and the ability to work independently with minimal supervision. Robust ownership — you ship, document, and support what you build. A collaborative mindset paired with the confidence to advocate for the right technical path.
