You'll work on building robust agentic systems, designing evals, and managing model deployment at scale. This role is ideal for engineers who want to push the boundaries of speech, LLMs, and agentic AI in production at scale.\n\nThe core responsibilities for the job include the following:\n\nSpeech and Voice Systems: \nOwn evaluation, selection, and integration of ASR/LLM/TTS/S2S model providers.\nBenchmark accuracy, latency, and noise robustness across language and code-switched settings, including noise cancellation and audio preprocessing variants.\nBuild and optimize real-time streaming voice pipelines that handle interruptions, endpointing, natural pauses, and real-world audio variability without breakdowns.\n\nModel Quality and Inference: \nAnalyze conversational quality of voice agents against human benchmarks and translate findings into prioritized model improvement roadmaps (fine-tuning, prompting, and harness engineering).\nDesign SFT datasets and lightweight eval frameworks for voice-agent quality at scale.\nOptimize LLM/ASR/TTS inference for in-house model deployments, including memory/KV-cache planning, GPU selection and sizing, and latency-throughput trade-offs for real-time voice workloads.\nHarden promptness, harness, and tool-calling reliability for production agents.\nWork on self-learning agents capable of continuous improvement by observing human workflows and feedback\n\nEngineering and Deployment: \nCollaborate with MLOps and Inference Providers to bring models into real-time, low-latency production environments\nWork with DataOps to create, refine, and build high-quality real-world datasets for in-house data needs.\nEnsure scalability, security, and reliability of deployed ML systems.\n\nCollaboration and Research: \nPartner closely with product and engineering teams to deliver production-ready features.\nStay on top of the latest advances in ASR, TTS, LLMs, speech systems, and real-time inference frameworks, and apply them to Nurix's roadmap.\n\nRequirements: \nBachelor's degree in computer science, AI/ML, or a related field.\n4+ years of hands-on ML engineering experience, with a focus on speech/NLP systems.\nStrong expertise in ASR, TTS, NLP, LLM inference and fine-tuning, and conversational voice systems.\nTrack record of training/fine-tuning models and deploying them in production.\nWorked closely with data operations teams for training/testing data annotation and post-release sanity checks.\nProficiency in Python backends and ML frameworks (PyTorch, vLLM, SGLang, Unsloth, Axolotl).\nExperience in designing low-latency, real-time ML applications.\nStrong understanding of ML lifecycle, evaluation, and deployment practices.\nContributions to open-source ML projects or research publications. Prior work on multilingual or Indian-context ASR/TTS systems.\nSkills\nASR, LLM, NLP, PyTorch, Python, SGLang, TTS, Unsloth, deployment, fine-tuning, inference, vLLM","description_format":"text","description_chars":3011,"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":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["LLM & Generative AI","Conversational AI","AI Agents"],"lifecycle":[{"event":"open","at":"2026-10-22T14:35:30Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":5,"expected_fill_days":29,"reasons":["seen:5","velocity","win:early"],"computed_at":"2026-10-28T05:59:10Z"},"pay":null,"html_url":"https://alion.io/job/nuplay-ai-ml-engineer","json_url":"https://alion.io/job/nuplay-ai-ml-engineer.json","meta":{"generated_at":"2026-10-28T11:44:04Z","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":15445,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-29T00:00:00Z"}},"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":47330},"rest":"https://alion.io/mcp/rest/get_company?id=47330"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fnuplay-ai-ml-engineer"},{"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%2Fnuplay-ai-ml-engineer"},{"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%2Fnuplay-ai-ml-engineer"},{"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/nuplay-ai-ml-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fnuplay-ai-ml-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3090631}},{"tool":"search_jobs","arguments":{"company":"nuplay.ai","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3090631},"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.
