Our vision is to unlock the full potential of magnetic intelligence through our proprietary quantum diamond technology and curated algorithms.\nBy 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.\nFrom 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.\nWhy Join Us\nWe’re a fast-growing deeptech startup building multiple bricks for the future of magnetic navigation. This is a unique opportunity to:\nPioneer magnetic navigation algorithms based on inertial systems\nWork directly with leadership on strategic and execution priorities \nDeploy and test your solution on different platforms\nCollaborate with world leading organizations in the PNT space\nHave real ownership and impact in a high-growth, mission-driven environment\nWho We’re Looking For\nWe’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.\nKey Responsibilities\nINS filter design & tuning - Design, implement, and tune Kalman-based and hybrid filters (e.g. EKF, UKF) for inertial navigation systems, balancing convergence speed, noise rejection, and drift compensation across operational scenarios.\nMagnetic navigation integration - Develop and refine sensor fusion algorithms that combine magnetometer data with IMU outputs, addressing magnetic anomaly mapping, hard/soft iron calibration, and geomagnetic model integration.\nHybrid systems architecture - Evaluate and iterate on hybrid navigation architectures (loosely-coupled, tightly-coupled, deeply-coupled), defining data flow, aiding source hierarchies, and fault-detection logic for robust multi-sensor operation.\nPerformance benchmarking & analysis - Define and run systematic benchmark suites against reference trajectories and truth data, tracking key metrics\nField testing & real-world validation - Plan and execute field trials across representative environments, capturing sensor logs, post-processing data, and closing the loop between lab simulation and real-world edge cases to drive algorithm refinement.\nRapid algorithm iteration - Prototype novel approaches quickly in simulation, apply structured tuning methodologies, and move promising candidates through hardware-in-the-loop testing with short iteration cycles from concept to validated result.\nCritical system-level problem solving - Diagnose ambiguous failure modes across the full signal chain - from raw sensor data to navigation output - proposing unconventional solutions where standard approaches fall short and documenting findings to build team knowledge.\nWhat We’re Looking For\n5 years of experience in a startup environment \nBackground in robotics, including INS systems EKF filters tuning\nDemonstrated experience customizing INS platforms with custom sensors\nExperience with robotics control software such as MOSA, ASPN, PNTOS ArduPilot\nExperience in autonomous platforms deployment\nComfortable wearing multiple hats and switching contexts quickly \nStrong problem-solver with a bias toward action \nExcellent communication skills (written and verbal) \nHigh level of discretion and professionalism\nNice-to-Haves\nExperience in deeptech, hardware, or scientific environments \nFamiliarity with compliance, grants, or government processes\nBilingual English/French\nWhat We Offer\nFlexible hybrid work environment \nOpportunity to shape both the company and its culture \nEquity \nGrowth opportunities as SBQuantum scales","description_format":"text","description_chars":4352,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"French","level":"Proficiency (C2)","optional":false},{"language":"English","level":"Proficiency (C2)","optional":false}]},"benefits":["Equity","Growth opportunities","Hybrid work"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Sensors & Transducers"],"lifecycle":[{"event":"open","at":"2026-09-26T09:18:11Z"}],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.207,"p_room":0.28,"age_days":140,"expected_fill_days":30,"reasons":["conf:34","win:tail","crowd:"],"computed_at":"2026-10-02T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/sbquantum-robotics-engineer","json_url":"https://alion.io/job/sbquantum-robotics-engineer.json","meta":{"generated_at":"2026-10-03T01:23:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":1338,"day_limit":5000,"remaining_today":3662,"minute_limit":60,"resets_at":"2026-10-04T00:00:00Z"}}}
