You’ll work directly with real-world agent data, apply frontier methods in production, and see your work ship into the product. By making agent behavior measurable and debuggable, your systems will support teams deploying agents across finance, legal, operations, and other high-stakes workflows. You will own projects end-to-end, with significant autonomy, and work closely with the team to build self-improving agent systems.\nWhat You'll Do:\nBuild AI systems to aggregate, index, and analyze large-scale long-running agent interaction data in order to extract meaningful signals\n\nDesign and implement post-training and optimization workflows to improve agents, both internally and for customers\n\nBuild agent platform infrastructure, including orchestration, runtimes, and developer tools that help teams define, test, deploy, and iterate on complex agent workflows\n\nBuild internal tools and infrastructure that support rapid experimentation, analysis, and training\n\nWork closely with product to integrate agents into customer-facing workflows\n\nCollaborate with external companies and research partners on frontier AI research\n\nWhat We're Looking For\nEvery hire clears three bars, no exceptions:\nAgency. You are intellectually curious, self-directed, and stay up to date with the latest research, blogs, trends, and ideas.\n\nDepth of thought. You can reason clearly about abstract systems, and ideally have experience working on agents, RL, or the infrastructure that supports them.\n\nOwnership. You own outcomes, not just tasks. You use freedom to experiment responsibly, make business-driven decisions, and focus first on work that moves the company forward.\n\nMore specifically, you should bring strength in at least one of the following areas:\nData quality, evaluation, benchmarking, and hands-on work with messy production data\n\nAgent systems built or evaluated in real-world or production settings\n\nReinforcement learning, post-training, agents, or machine learning fundamentals\n\nInfrastructure and systems work across training, data pipelines, evaluation, or model serving\n\nTranslating research into product while balancing customer constraints, technical tradeoffs, and business impact\n\nTurning ambiguous problems into clear, well-designed plans","description_format":"text","description_chars":2503,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Peripherals"],"lifecycle":[{"event":"open","at":"2026-09-12T16:44:25Z"}],"liveness":{"score":6,"band":"cold","label":"Long shot","p_open":1,"p_active":0.206,"p_room":0.28,"age_days":255,"expected_fill_days":43,"reasons":["conf:8","win:tail","crowd:"],"computed_at":"2026-09-24T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/judgmentlabs-applied-ai-engineer","json_url":"https://alion.io/job/judgmentlabs-applied-ai-engineer.json","meta":{"generated_at":"2026-09-24T09:30:41Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers"}}
