In this role, you'll drive end-to-end computer vision solutions processing hundreds of thousands of vehicle inspections annually into reliable, actionable insights, directly reducing inspection turnaround time, improving valuation accuracy, and scaling the capabilities of our inspection platform. You'll design and train damage detection models while architecting the high-throughput serving infrastructure needed to keep those models performant under real production loads. As ACV continues to grow, you'll play a direct role in ensuring our inspection capabilities remain accurate, efficient, and resilient at scale.\nThis role goes beyond executing on a defined roadmap. You'll identify opportunities, shape solutions end-to-end, and take ownership of outcomes. You connect the dots between stakeholder needs and what's technically feasible, bringing recommendations grounded in both theory and practical constraints. When you hear a narrow question, you think about the broader system it lives in and build toward that.\nThe core responsibilities of this role are:\nDesign and train high-performance computer vision models for automated damage detection, focusing on precision, recall, and model robustness.\nArchitect and maintain high-throughput, containerized microservices for model serving using REST/gRPC to ensure low-latency performance.\nCollaborate with business stakeholders to translate complex inspection requirements into scalable, production-grade ML solutions.\nOwn the end-to-end model lifecycle, from experimentation and design to deployment and optimization in high-traffic environments.\nDesign and maintain robust data pipelines using Kafka to ensure high-fidelity inputs for model serving and inference.\nRequired Qualifications:\nGraduate education (MS or PhD) in a computationally intensive domain or equivalent work experience.\n5+ years of prior computer vision experience\nAdvanced proficiency with Computer Vision frameworks (e.g., PyTorch, OpenCV, TensorFlow) and Python/SQL.\nExperience designing and maintaining visual data annotation pipelines and evaluation frameworks for complex, real-world image datasets.\nExperience optimizing high-latency models for real-time inference\nBackend software engineering experience in the cloud (AWS / GCP) with a focus on microservices (docker) and the ML model development lifecycle.\nExperience building and maintaining streaming data pipelines (e.g., Kafka) for real-time model serving.\nPreferred Qualifications:\nKnowledge of ML frameworks and libraries, such as Kubeflow, Databricks, KServe and so on\nExperience designing evaluation frameworks for complex visual data\nExperience leading technical design reviews","description_format":"text","description_chars":2815,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Auctions","Marketplaces"],"lifecycle":[{"event":"open","at":"2026-10-22T12:09:46Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.349,"p_room":0.28,"age_days":114,"expected_fill_days":36,"reasons":["conf:3","stale_co","velocity","win:tail","crowd:"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/acv-auctions-machine-learning-engineer-iv-data-2","json_url":"https://alion.io/job/acv-auctions-machine-learning-engineer-iv-data-2.json","meta":{"generated_at":"2026-10-24T16:58:18Z","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":24558,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"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":179324},"rest":"https://alion.io/mcp/rest/get_company?id=179324"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Facv-auctions-machine-learning-engineer-iv-data-2"},{"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%2Facv-auctions-machine-learning-engineer-iv-data-2"},{"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%2Facv-auctions-machine-learning-engineer-iv-data-2"},{"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/acv-auctions-machine-learning-engineer-iv-data-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Facv-auctions-machine-learning-engineer-iv-data-2"}]}
