As a Guidance, Navigation & Control (GNC) Engineer, you will design the algorithms that let our spacecraft know where they are, decide where to go, and get there precisely. You will own estimation, attitude and orbit determination, and control across the full loop - from math on the whiteboard to flight software running on hardware in high-stakes, resource-constrained environments.\nResponsibilities\nDesign and implement guidance, navigation, and control algorithms for spacecraft attitude determination and control (ADCS), orbit determination, and maneuver planning\nDevelop state estimation and sensor fusion (e.g., Kalman/nonlinear filters) fusing IMU, star tracker, sun sensor, GPS, and other sensor data\nModel spacecraft dynamics and orbital mechanics, and design controllers (e.g., PID, LQR, robust/adaptive) for pointing, station-keeping, and trajectory tracking\nBuild high-fidelity simulation environments to validate GNC performance across nominal and off-nominal conditions\nImplement and test GNC algorithms in flight software, and support hardware-in-the-loop verification\nRun Monte Carlo analyses and closed-loop verification to characterize performance, stability, and margins\nCollaborate with software, systems, avionics, and operations engineers to integrate GNC into the full vehicle\nSupport on-orbit operations, commissioning, and anomaly resolution for GNC subsystems\nBasic Qualifications\nBachelor's degree in Aerospace, Mechanical, Electrical Engineering, Robotics, Applied Mathematics, or a related field\nStrong foundation in control theory, linear algebra, and dynamics\nProgramming experience in Python and/or C/C++\nExperience with simulation and analysis tools such as MATLAB/Simulink or equivalent Python stacks\nExperience with version control systems such as Git\nWhat We're Looking For\nWe're building technology that hasn't been done before. Experience is helpful, but curiosity, drive, and the ability to learn quickly matter more. If you're excited about spacecraft, enjoy solving hard engineering problems, and want to help build something new, we encourage you to apply - whether you're early in your career or more experienced.\nPreferred Skills\nCreative problem solver with strong first-principles thinking, capable of assessing risk and making decisions with limited data.\nExperience in a nimble, technical engineering role, with a scrappy, entrepreneurial approach to meeting tight time or budget constraints.\nHands-on experience with spacecraft ADCS, orbital mechanics, or trajectory design\nExperience implementing estimators or controllers in embedded / flight software\nFamiliarity with sensor calibration, sensor fusion, and hardware-in-the-loop testing\nExperience with real built hardware - student design teams (rocketry, CubeSat, autonomous vehicles), research, or industry\nExcellent verbal and written communication skills, collaborative team player, and detail-oriented with a focus on quality.\nAdditional Requirements\nExtended hours and weekend work may be required to support critical project and mission milestones.\nThis role requires a physical presence at the Ottawa facility.\nCompensation\nSalary: $75,000 - $110,000 CAD per year\nEquity: 0.1% - 0.5%\nIf you're excited about shaping the future of space systems, we'd love to hear from you.\nPlease submit any projects that you have worked on.","description_format":"text","description_chars":3444,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-15T02:38:30Z"}],"visa":[],"liveness":{"score":9,"band":"cold","label":"Long shot","p_open":1,"p_active":0.316,"p_room":0.28,"age_days":62,"expected_fill_days":21,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-15T05:46:00Z"},"pay":{"stated_usd_annual":77032,"is_top_pay":false},"html_url":"https://alion.io/job/spaceium-inc-guidance-navigation-control-gnc-engineer","json_url":"https://alion.io/job/spaceium-inc-guidance-navigation-control-gnc-engineer.json","meta":{"generated_at":"2026-10-15T18:31:50Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":28124,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3779071},"rest":"https://alion.io/mcp/rest/get_company?id=3779071"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fspaceium-inc-guidance-navigation-control-gnc-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fspaceium-inc-guidance-navigation-control-gnc-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fspaceium-inc-guidance-navigation-control-gnc-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/spaceium-inc-guidance-navigation-control-gnc-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fspaceium-inc-guidance-navigation-control-gnc-engineer"}]}
