This role will focus on advancing our perception stack by refining our data engines, architecting robust 2D/3D vision models, and deploying them on production hardware so our robots can handle the chaotic reality of the physical world.\nResponsibilities:\nArchitect Multi-Modal Vision Systems: You will design and train models that fuse 2D inputs with 3D geometry to solve complex grasping and scene understanding tasks.\nLead End-to-End Model Deployment: You will own the transition from research to reality. This includes model graph optimization, quantization (TensorRT), and runtime integration to ensure low-latency inference on our edge compute hardware (NVIDIA Orin).\nDrive Technical Excellence: As a senior member of the team, you will conduct rigorous code reviews, mentor junior engineers, and contribute to the strategic perception roadmap.\nOwn the Data Strategy: You will take ownership of our existing labeled dataset and pipeline. You will identify bottlenecks, improve data quality, implement active learning strategies to systematically resolve edge cases and improve model robustness.\nEnsure Production Reliability: You will write high-performance production code (Python/C++) to seamlessly integrate perception outputs into the broader robotic control stack, prioritizing safety and system stability.\nSkills:\n5+ Years of Experience in Computer Vision and Machine Learning, with a track record of shipping ML products to the physical world (Robotics, AV, or IoT).\nExpert-level Python and PyTorch skills. Working knowledge of C++ for deployment and system integration.\nExperience with 2D Vision (YOLO, MaskRCNN, Transformers) and 3D Vision (PointNet, grasp generation, multi-view geometry, camera calibration).\nYou are proficient with inference optimization tools such as TensorRT, ONNX Runtime, or CUDA to maximize hardware utilization.\nYou have experience curating large-scale datasets, detecting statistical bias, and automating quality assurance within the ML pipeline.\nYou can translate high-level product requirements into specific engineering tasks and explain technical trade-offs to non-expert stakeholders.\nFamiliarity with Docker, AWS/GCP (S3, EC2), labeling platforms and experiment tracking tools.","description_format":"text","description_chars":2350,"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":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Transportation & Logistics","Supply Chain"],"lifecycle":[{"event":"open","at":"2026-10-03T05:44:19Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 9","filings_12m":9,"filings_prev_12m":10,"green_card_filings_12m":0,"median_offered_wage_usd":147500,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:08:04+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":0}],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.3,"p_room":0.28,"age_days":290,"expected_fill_days":92,"reasons":["conf:2","ghost","win:tail","crowd:"],"computed_at":"2026-10-05T05:45:15Z"},"pay":{"stated_usd_annual":175000,"is_top_pay":false},"html_url":"https://alion.io/job/pickle-robot-senior-machine-learning-engineer-perception","json_url":"https://alion.io/job/pickle-robot-senior-machine-learning-engineer-perception.json","meta":{"generated_at":"2026-10-06T02:51:36Z","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","counted_by":"address","units_charged":1,"used_today":4275,"day_limit":5000,"remaining_today":725,"minute_limit":60,"resets_at":"2026-10-07T00:00:00Z"}},"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":176523},"rest":"https://alion.io/mcp/rest/get_company?id=176523"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fpickle-robot-senior-machine-learning-engineer-perception"},{"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%2Fpickle-robot-senior-machine-learning-engineer-perception"},{"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%2Fpickle-robot-senior-machine-learning-engineer-perception"},{"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/pickle-robot-senior-machine-learning-engineer-perception\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fpickle-robot-senior-machine-learning-engineer-perception"}]}
