The company’s mission is to empower organizations to confidently scale their data operations across multi-cloud and on-premises environments while leveraging the power of AI without compromising security.\nSentra’s unique approach enables enterprises to autonomously scan their environments without the need for agents, ensuring that data remains securely within their cloud or on-premises infrastructure. This innovative methodology sets us apart in the industry, providing organizations with control and visibility over their sensitive data at all times. Our commitment to excellence in data security posture management and data detection and response makes Sentra a leader in the field.\nAs a Data Scientist, you will lead research and development of advanced AI models - from LLMs and NER systems to generative and self-supervised architectures - that power Sentra’s data classification capabilities. You’ll explore emerging AI techniques, build prototypes and bring them to production.\nResponsibilities\nResearch & Innovation - Design and evaluate novel AI and NLP approaches (LLMs, generative models, self-supervised methods) to enhance entity recognition and contextual understanding.\nPrototype to Production - Develop proof-of-concept models and collaborate with MLOps and engineering teams to harden and deploy them in production environments.\nExperimentation Frameworks - Build tools and pipelines for large-scale experimentation, model evaluation, and continuous improvement.\nData-Driven Insights - Leverage Sentra’s unique datasets to define key metrics, drive iterative improvements, and balance precision-recall trade-offs.\nCross-Functional Collaboration - Work closely with Product and Engineering to align research direction with business and customer impact.\nRequirements\n7+ years of experience in machine learning or AI research, with deep expertise in NLP, LLMs, or Generative AI.\nProven track record of delivering AI models into production, including model deployment, monitoring, and lifecycle management.\nStrong proficiency in Python and deep learning frameworks (e.g., PyTorch, TensorFlow).\nHands-on experience with large-scale data processing (Spark, Ray, or similar) and cloud platforms (AWS, GCP, or Azure).\nSolid understanding of MLOps practices, including continuous training, evaluation, and model versioning.\nExcellent communication and collaboration skills, especially when working across product and engineering teams.\nProffered Qualifications\nExperience in data security, privacy, or compliance domains.\nFamiliarity with LLM fine-tuning, and prompt optimization.\nExperience with cloud-based AI training and fine-tuning frameworks.\nAdvanced degree (Master’s or Ph.D.) in Computer Science, Machine Learning, or related field.","description_format":"text","description_chars":2839,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Israel","iso":"IL","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Data Loss Prevention"],"lifecycle":[{"event":"open","at":"2026-11-04T13:35:02Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":29,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-11-06T05:58:05Z"},"pay":null,"html_url":"https://alion.io/job/sentra-data-science","json_url":"https://alion.io/job/sentra-data-science.json","meta":{"generated_at":"2026-11-06T23:23:51Z","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":2823,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-07T00:00:00Z"}},"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":180445},"rest":"https://alion.io/mcp/rest/get_company?id=180445"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsentra-data-science"},{"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%2Fsentra-data-science"},{"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%2Fsentra-data-science"},{"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/sentra-data-science\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsentra-data-science"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3746736}},{"tool":"search_jobs","arguments":{"company":"sentra.io","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3746736},"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.
