Operating at the intersection of technical customer leadership, AI expertise, and technical project management, you will guide an interdisciplinary team of engineers, algorithm developers, linguists, and infrastructure experts, driving alignment and execution. You are a technical leader and trusted customer partner, translating complex AI concepts, building deep client trust, and driving project scope, milestones, risks, and execution, while balancing resources, timelines, and quality.\nRequirements\nKey Requirements\nDeep Technical AI Expertise:\nStrong technical understanding of modern AI/LLM systems and model training processes, with the ability to engage credibly with engineers and algorithm developers.\nAbility to navigate technical trade-offs and provide sound technical judgment across the AI lifecycle, including training, evaluation, data and inference.\nProject Management:\nAbility to define and drive scope, milestones, priorities, dependencies and success criteria, while proactively managing risks and blockers.\nStrong execution and communication skills, with the ability to create clarity in complex and ambiguous environments.\nOrchestrating multiple high-stakes, expensive projects and navigating internal and external stakeholders under tight schedules and technical uncertainty.\nTechnical Customer Relations: Driven by a genuine interest in customer success, you possess exceptional client-facing skills with a talent for managing high-profile relationships, establishing healthy communication routines, understanding nuanced customer needs, and building lasting trust.\nLeadership & Cross-Functional Influence:\nProven ability to lead without authority across diverse, interdisciplinary teams while fostering strong internal routines and collaboration.\nWorking with internal and external senior management, including legal and finance, across different resolutions and depths.\nProduct Definition: Ability to define what a \"good\" model output looks like. Experience writing data specs, resolving behavior tradeoffs, establishing success metrics, and curating golden datasets.\nAbout Us\nAI21 is one of the leading, most experienced foundational AI labs in the world.\nAs companies start to deploy AI agents at scale, they face challenges rooted in missing expertise and ownership. We help companies scale their AI agents - sustainably. We automatically reduce token cost and waste without harming frontier quality, replacing weeks or months of manual tuning. This is achievable by applying advanced research and methodologies across the stack, from intelligent model routing and up to harness and model training.","description_format":"text","description_chars":3377,"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":[{"name":"Israel","iso":"IL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["LLM & Generative AI","Natural Language Processing","Foundation Models","AI Research Labs"],"lifecycle":[{"event":"open","at":"2026-11-13T11:43:39Z"}],"visa":[],"liveness":{"score":84,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.842,"p_room":1,"age_days":5,"expected_fill_days":28,"reasons":["conf:1","win:early"],"computed_at":"2026-11-13T13:35:21Z"},"pay":null,"html_url":"https://alion.io/job/ai21-labs-technical-project-manager-post-training","json_url":"https://alion.io/job/ai21-labs-technical-project-manager-post-training.json","meta":{"generated_at":"2026-11-13T13:35:21Z","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":27256,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-14T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":175},"rest":"https://alion.io/mcp/rest/get_company?id=175"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fai21-labs-technical-project-manager-post-training"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"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%2Fai21-labs-technical-project-manager-post-training"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fai21-labs-technical-project-manager-post-training"},{"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/ai21-labs-technical-project-manager-post-training\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fai21-labs-technical-project-manager-post-training"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4234916}},{"tool":"search_jobs","arguments":{"company":"ai21.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4234916},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
