You will define modeling methodology, build production ML systems, and apply modern AI and agentic capabilities across our data products.\nYou bring 8+ years of experience, deep expertise in machine learning and modern AI, and the technical range to take methodology from research through production deployment. You are an active collaborator with engineering, product, and partner teams, and an advocate for rigorous, defensible modeling practice.\nWhat You'll Do\nModeling and ML Development\nOwn end-to-end delivery of data science projects, from problem scoping through production deployment.\n\nDefine and ship modeling methodology that powers Samba's data products, including model selection, evaluation frameworks, and reproducibility standards.\n\nApply solid command of core ML and statistics (regression, classification, clustering, model evaluation, experimental design, causal inference) to billion-row, real-world data.\n\nBuild production-quality Python and PySpark on Databricks: well-tested, documented, reusable.\n\nPartner with Data Engineering to define data requirements, validate pipelines, and ensure model inputs are reliable and production-ready.\n\nAI and Agentic Capabilities\nBuild and operate advanced AI systems using modern methodologies: retrieval-augmented generation (RAG), LLM-augmented modeling and Graph Neural Networks. Design AI-driven modeling approaches that improve as signals evolve, supporting agentic decision-making at platform scale.\n\nIntegrate LLMs and agentic workflows into production ML pipelines where they extend modeling capability and unlock new product surfaces.\n\nTechnical Contribution and Collaboration\nDrive technical design for modeling components within your scope, producing clear solution documents covering problem statement, approach, metrics, and trade-offs.\n\nTranslate business requirements into modeling solutions in close collaboration with product, engineering, and go-to-market partners.\n\nUphold high standards for production-quality data science.\n\nMentor data scientists on the team through structured feedback, pairing, and design review.\n\nMLOps and Production Practice\nEstablish and operate MLOps practices: experiment tracking, pipeline orchestration (Airflow), model monitoring, retraining workflows, and reproducibility standards.\n\nApply privacy-compliant data handling practices, including GDPR, CCPA, and Samba's data governance policies.\n\nWho You Are\nRequired\n8+ years of hands-on data science experience with a Bachelor's degree in Statistics, Data Science, Computer Science, Mathematics, or a related quantitative field (or 6+ years with a Master's, 3+ years with a PhD, or equivalent).\n\nDemonstrated ability to own and deliver complex, multi-sprint data science projects from problem scoping through production deployment.\n\nSolid command of core ML and statistics, including neural networks, regression, classification, clustering, model evaluation, experimental design, and causal inference, applied to billion-row datasets.\n\nTrack record of building methodology, not just applying it: data analysis, model selection, evaluation frameworks, and solid documentation of decision processes\n\nProduction experience with vector databases (Pinecone, Weaviate, Milvus, pgvector, or equivalent) for retrieval, matching, or inference at scale.\n\nAdvanced Python with production-quality, tested code; strong SQL and PySpark on billion-row datasets.\n\nDatabricks, Delta Lake, and job orchestration (Airflow); hands-on production experience on AWS, GCP, and Databricks.\n\nMLOps proficiency: experiment tracking, pipeline orchestration, model monitoring, reproducible deployment.\n\nExperience designing and operating agentic AI systems in production: prompt engineering, agent orchestration, tool use, or integration of LLMs into ML pipelines.\n\nA clear communicator who translates technical work into design docs, user stories, and cross-functional conversations.\n\nAn active mentor who invests in others, gives direct feedback, and raises the bar for the team as a whole.\n\nPreferred\nKnowledge graph design (RDF, OWL, SPARQL, or equivalent graph frameworks), Natural Language Processing, Background in ad tech, CTV/OTT, ACR, audience activation, identity resolution, or measurement methodologies.\n\nExperience with causal inference (A/B testing, synthetic control, uplift modeling).","description_format":"text","description_chars":4464,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Advertising","Media & Audience Measurement"],"lifecycle":[{"event":"open","at":"2026-09-06T07:20:12Z"}],"visa":[],"liveness":{"score":35,"band":"fade","label":"Fading","p_open":1,"p_active":0.795,"p_room":0.44,"age_days":144,"expected_fill_days":143,"reasons":["conf:3","win:tail","crowd:"],"computed_at":"2026-10-25T05:49:26Z"},"pay":null,"html_url":"https://alion.io/job/samba-tv-senior-data-scientist","json_url":"https://alion.io/job/samba-tv-senior-data-scientist.json","meta":{"generated_at":"2026-10-25T10:47:46Z","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":15390,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-26T00:00:00Z"}},"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":171913},"rest":"https://alion.io/mcp/rest/get_company?id=171913"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsamba-tv-senior-data-scientist"},{"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%2Fsamba-tv-senior-data-scientist"},{"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%2Fsamba-tv-senior-data-scientist"},{"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/samba-tv-senior-data-scientist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsamba-tv-senior-data-scientist"}]}
