We create capabilities that multiply the effectiveness of every individual and withstand the world’s toughest environments.\nWe serve the people who build, operate, maintain, and defend our way of life. From technicians and engineers to first responders and service members, they embody the hard work, ingenuity, and meritocratic values that drive Western prosperity. Yet too often they are forced to rely on outdated tools that fail under modern pressures. Rivet exists to reset that priority.\nAt Rivet, you’ll join a mission-driven team that fuses disciplines to deliver decisive outcomes where they matter most. Whether shaping our technology, strengthening our partnerships, or building our culture, every role here contributes to equipping the front lines with the modern systems they deserve.\nWork Authorization Requirement: Due to the nature of our business and compliance with federal regulations, all candidates must be a \"U.S. Person\". Upon hire, you will be required to provide documentation verifying your status as a U.S. Citizen, a lawful permanent resident, or a protected individual under 8 U.S.C. 1324b(a)(3).\nSummary\nRivet is looking for a Software Engineer focused on sensor fusion for real-time AR systems on Android and embedded Linux devices. This role sits at the intersection of perception, tracking, and real-time XR experiences - integrating IMUs, cameras, depth sensors, and other device inputs into robust, low-latency spatial computing systems. You will develop the software pipelines that enable accurate 3DoF/6DoF tracking, spatial awareness, and stable AR experiences in demanding operational environments. The role spans real-time systems, state estimation, runtime integration, and performance optimization on constrained hardware platforms. You will work closely with hardware, firmware, computer vision, and XR application teams to deliver performant and reliable sensor-driven AR capabilities.\nResponsibilities\nDevelop sensor fusion systems for AR/XR devices using IMU, camera, depth, and other sensor inputs.\n\nImplement tracking, calibration, synchronization, filtering, and state estimation pipelines for spatial computing applications.\n\nBuild performant C++ and C# systems for real-time XR applications and device integration.\n\nIntegrate with OpenXR and AR runtimes for cross-platform compatibility.\n\nOptimize latency, timing, motion stability, and tracking performance on Android and embedded Linux platforms.\n\nDevelop tooling, visualization, and debugging workflows for sensor validation and performance analysis.\n\nBuild companion applications and device services in Java/Kotlin for Android-based systems.\n\nUse Python for simulation, automation, testing, and build/CI workflows.\n\nCollaborate across hardware, firmware, perception, graphics, and backend teams to deliver end-to-end AR capabilities.\n\nRequirements\nDeep experience building real-time sensor fusion, robotics, AR/VR, perception, or spatial computing systems.\n\nMS + at least 3 years (or PhD + at least 1 year) of relevant professional experience.\n\nStrong fundamentals in sensor fusion, state estimation, filtering, coordinate systems, motion tracking, and real-time systems.\n\nProficient in C++ and/or C# for performance-critical applications.\n\nExperience developing on Android or embedded Linux systems.\n\nFamiliarity with XR and perception frameworks such as OpenXR, ARCore, SLAM/VIO pipelines, or related technologies.\n\nStrong understanding of latency optimization, synchronization, profiling, and CPU/GPU/memory tradeoffs.\n\nExperience with Java/Kotlin for Android services and peripheral integration.\n\nPython experience for scripting, simulation, automation, or test infrastructure.\n\nAbility to collaborate across hardware, firmware, computer vision, and cloud/backend systems.\n\nTrack record of shipping complex real-time systems or XR capabilities.\n\nPreferred Qualifications\nPhD in a relevant discipline with 5+ years of industry experience, or MS with 10+ years of industry experience.\n\nExperience with visual-inertial odometry (VIO), SLAM, Kalman filtering, or probabilistic estimation techniques.\n\nExperience with Unity, Unreal Engine, StereoKit, or comparable 3D/XR engines.\n\nExperience working on wearable, robotics, aerospace, defense, or embedded sensing platforms.\n\nCompensation may vary within the posted range based on relevant experience, skills, education, and other job-related factors. In addition to base salary, this role may be eligible for equity and other forms of compensation. Eligible employees also receive a competitive benefits package, including unlimited PTO.\nRivet is an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to any characteristic protected by applicable law. Certain roles may require U.S. Person status, security clearance eligibility, or other requirements imposed by law or government contract.","description_format":"text","description_chars":5098,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":["Equity","Unlimited PTO"],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Logistics"],"lifecycle":[{"event":"open","at":"2026-10-09T12:34:04Z"}],"visa":[],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.303,"p_room":0.28,"age_days":100,"expected_fill_days":29,"reasons":["conf:1","stale_co","win:tail","crowd:"],"computed_at":"2026-10-10T05:45:15Z"},"pay":{"stated_usd_annual":240000,"is_top_pay":false},"html_url":"https://alion.io/job/rivet-software-engineer-sensor-fusion","json_url":"https://alion.io/job/rivet-software-engineer-sensor-fusion.json","meta":{"generated_at":"2026-10-11T23:05:26Z","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":13585,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-12T00:00:00Z"}},"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":3870400},"rest":"https://alion.io/mcp/rest/get_company?id=3870400"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frivet-software-engineer-sensor-fusion"},{"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%2Frivet-software-engineer-sensor-fusion"},{"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%2Frivet-software-engineer-sensor-fusion"},{"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/rivet-software-engineer-sensor-fusion\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frivet-software-engineer-sensor-fusion"}]}
