We're fixing that, in the open.\nAbout EkaCare\nEkaCare is India's connected healthcare platform: an EMR that doctors run their practices on, a personal health record used by millions of Indians, and one of the deepest integrations with India's ABDM digital-health rails. Our Parrotlet family of medical models already serves Indian doctors in production, and we open-source our work where it counts.\nThe role\nPost-training is where a base model becomes a doctor's tool, and where most medical models quietly fail. You'll turn a strong pre-trained base into a model that follows instructions, knows what it doesn't know, stays safe in a clinical setting, and does it in a dozen Indian languages.\nWhat you'll do\nDesign SFT/IFT data mixes and chat templates for clinical tasks, and reformat the world's medical data to match.\nRun preference optimisation (DPO/ORPO/GRPO-class) and reward-model training; own the ablation grid.\nBuild RL loops with verifiable medical rewards, with practising physicians in the loop. Real doctor-in-the-loop, not proxy labels.\nCreate agentic and tool-use training data for healthcare workflows.\nLive in the eval → error-analysis → iterate loop; red-team your own model before the world does.\nWhat we look for\n2-4 years in ML with hands-on post-training of ≥7B open-weights models; you've shipped SFT plus at least one preference-optimisation method end to end, not a notebook demo.\nFluency with the open post-training stack (TRL / NeMo RL / OpenRLHF; vLLM for rollouts).\nStrong empirical taste: ablation discipline, LLM-judge literacy, contamination paranoia.\nSolid engineering, Python, distributed-training basics, comfort in a fast codebase.\nBonus\nPPO/GRPO at scale; reward-hacking war stories.\nMultilingual or medical/clinical alignment work.\nOpen-source contributions people actually use.","description_format":"text","description_chars":2081,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["EHR & Clinical Software","Practice Management Software","Consumer Health Apps"],"lifecycle":[{"event":"open","at":"2026-08-10T10:54:34Z"}],"visa":[],"liveness":{"score":12,"band":"cold","label":"Long shot","p_open":1,"p_active":0.338,"p_room":0.35,"age_days":71,"expected_fill_days":30,"reasons":["conf:2","velocity","win:tail"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/eka-care-ml-research-engineer-post-training-llms","json_url":"https://alion.io/job/eka-care-ml-research-engineer-post-training-llms.json","meta":{"generated_at":"2026-10-21T09:06:53Z","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":12917,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":59359},"rest":"https://alion.io/mcp/rest/get_company?id=59359"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Feka-care-ml-research-engineer-post-training-llms"},{"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%2Feka-care-ml-research-engineer-post-training-llms"},{"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%2Feka-care-ml-research-engineer-post-training-llms"},{"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/eka-care-ml-research-engineer-post-training-llms\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Feka-care-ml-research-engineer-post-training-llms"}]}
