Data Scientist / ML Engineer (Generative AI)\nExperience: 5-10 years\nLocation: Onsite / Offshore (Flexible)\nPrimary Objective\nWe are seeking a Senior Data Scientist / ML Engineer specializing in Generative AI to design, evaluate, optimize, and productionize AI/ML solutions for enterprise applications-including RAG systems, AI agents, intelligent automation, and model evaluation platforms.\nThe role focuses on improving AI accuracy and retrieval quality, reducing hallucinations, benchmarking LLMs, and building reliable solutions for enterprise-scale deployments.\nSuccess looks like: measurable gains in retrieval/answer quality, robust evaluation frameworks in production, and clear collaboration with AI engineering to ship governed, reliable GenAI systems.\nKey Responsibilities\nPrimary\nDesign and develop machine learning and Generative AI solutions. \nBuild and optimize RAG pipelines, retrieval strategies, embeddings, and semantic search. \nEvaluate and benchmark LLMs for accuracy, performance, and reliability. \nDevelop AI evaluation frameworks for hallucination detection, accuracy measurement, bias/toxicity detection, and ground-truth validation. \nOptimize prompts, models, and retrieval workflows. \nCollaborate with AI engineering teams to deploy models into production. \nAlso expected\nCreate training, validation, and testing datasets. \nPerform model benchmarking, A/B testing, and performance analysis. \nFine-tune foundation models when required. \nImplement model monitoring, observability, and ongoing evaluation processes. \nMust-Have Experience & Skills\n5-10 years of experience in data science, machine learning, or related applied ML roles. \nStrong Python programming skills, with Pandas, NumPy, and Scikit-learn. \nStrong foundation in supervised/unsupervised learning, statistical modeling, feature engineering, and model evaluation techniques. \nHands-on Generative AI experience with LLM evaluation, prompt engineering, RAG architectures, embedding models, fine-tuning approaches, and agent evaluation frameworks. \nExperience with PyTorch and/or TensorFlow. \nExposure to OpenAI models, Claude, Gemini, and/or open-source LLMs. \nExperience with vector databases, semantic search, and retrieval optimization. \nExperience delivering or supporting production AI/ML solutions in enterprise environments. \nExperience working with distributed onshore/offshore teams. \nPreferred Skills\nDatabricks, MLflow, and Spark. \nGraphRAG and Knowledge Graphs; exposure to Neo4j. \nResponsible AI, Explainable AI, and AI governance. \nBanking or Financial Services domain experience. \nFamiliarity with Azure AI Foundry, AWS Bedrock, Kubernetes, and AI observability platforms. \nSoft Skills\nClear communication with engineering and business stakeholders. \nAbility to translate evaluation results into actionable model/product decisions. \nComfortable owning quality metrics and trade-offs (accuracy, latency, cost, risk) in a delivery setting. \nCompensation, Benefits and Duration\nMinimum Compensation: USD 60,000\nMaximum Compensation: USD 210,000\nCompensation is based on actual experience and qualifications of the candidate. The above is a reasonable and a good faith estimate for the role.\nMedical, vision, and dental benefits, 401k retirement plan, variable pay/incentives, paid time off, and paid holidays are available for full time employees.\nThis position is available for independent contractors\nNo applications will be considered if received more than 120 days after the date of this post.","description_format":"text","description_chars":3503,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["401k plan","Retirement plans"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","IT Consulting & Digital Transformation"],"lifecycle":[{"event":"open","at":"2026-10-23T07:32:17Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.249,"p_room":0.28,"age_days":85,"expected_fill_days":16,"reasons":["conf:24","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-11-04T06:34:25Z"},"pay":{"stated_usd_annual":60000,"is_top_pay":false},"html_url":"https://alion.io/job/photon-senior-data-scientist-ml-engineer-gen-ai-boston","json_url":"https://alion.io/job/photon-senior-data-scientist-ml-engineer-gen-ai-boston.json","meta":{"generated_at":"2026-11-04T21:30:57Z","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":33416,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-05T00:00:00Z"}},"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":3186451},"rest":"https://alion.io/mcp/rest/get_company?id=3186451"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fphoton-senior-data-scientist-ml-engineer-gen-ai-boston"},{"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%2Fphoton-senior-data-scientist-ml-engineer-gen-ai-boston"},{"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%2Fphoton-senior-data-scientist-ml-engineer-gen-ai-boston"},{"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/photon-senior-data-scientist-ml-engineer-gen-ai-boston\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fphoton-senior-data-scientist-ml-engineer-gen-ai-boston"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3139168}},{"tool":"search_jobs","arguments":{"company":"photon.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3139168},"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.
