We are starting out with understanding and building hardware; electronics systems and semiconductors where AI can design and create beyond human cognitive limits.\nAbout the Team\nBacked by Silicon Valley’s top investors, Stanford University, and CEOs/Presidents of Google, AMD, Broadcom, Marvell, etc. We are a team of previous Stanford professors, SAIL researchers, Olympiad medalists (IPhO, IOI, etc.), CTOs of Synopsys & GlobalFoundries, Head of Sales & CRO of Cadence, former US Secretary of Defense, National Security Advisor, and Senior Foreign-Policy Advisor to four US presidents.\nPost-Training\nIn this role, you will post-train frontier models to autonomously perform complex tasks across the semiconductor design and verification pipeline. Models you train will propose and optimize chip architectures, generate and refine RTL code, run simulations, identify verification gaps, and iteratively improve designs - accelerating the pace of semiconductor innovation.\nYou will collaborate with leading experts in hardware design, verification, and computer architecture to design rich reinforcement learning environments that capture the intricacies of chip design workflows. You’ll develop structured reward functions, scaling strategies, and evaluation frameworks that push models toward higher reliability, efficiency, and creativity in semiconductor reasoning.\nYour work will directly advance the goal of creating AI systems capable of reasoning about, designing, and verifying next-generation silicon systems.\nYou might thrive in this role if you have experience with\nCreating and scaling RL environments for LLMs or multimodal agents\n\nBuilding high-quality evaluation datasets and benchmarks for complex reasoning or design tasks\n\nWorking closely with domain experts in hardware and verification to define evaluation metrics, constraints, and simulation conditions\n\nDesigning reward functions and feedback pipelines that balance correctness, performance, and design efficiency\n\nRunning large-scale RL fine-tuning or post-training experiments for frontier models\n\nApplying reinforcement learning or curriculum learning to structured reasoning or symbolic domains","description_format":"text","description_chars":2306,"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":["EDA Software","AI Agents"],"lifecycle":[{"event":"open","at":"2026-09-11T02:41:44Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 4","filings_12m":4,"filings_prev_12m":3,"green_card_filings_12m":0,"median_offered_wage_usd":192500,"route":null,"cap_exempt":false,"checked_at":"2026-10-15T11:24:14+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)"],"filings_for_role_12m":1}],"liveness":{"score":28,"band":"fade","label":"Fading","p_open":1,"p_active":0.626,"p_room":0.44,"age_days":344,"expected_fill_days":338,"reasons":["conf:0","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/voltai-research-engineer-post-training","json_url":"https://alion.io/job/voltai-research-engineer-post-training.json","meta":{"generated_at":"2026-10-17T12:34:59Z","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":16686,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"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":685840},"rest":"https://alion.io/mcp/rest/get_company?id=685840"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fvoltai-research-engineer-post-training"},{"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%2Fvoltai-research-engineer-post-training"},{"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%2Fvoltai-research-engineer-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/voltai-research-engineer-post-training\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fvoltai-research-engineer-post-training"}]}
