the exercise of critical thinking, analyzing and assessing problems and implications, identifying patterns, making connections of underlying issues, understanding risks and developing mitigation strategies, and taking ownership of the outcome\n- Teamwork and communication - putting our collective best together through documentation, collaboration, relationship-building, listening, empathy, recruiting, and evangelism\n- Prior experience in a high-growth startup or SaaS company is preferred\n- Familiarity with a cloud-based data stack (e.g. Snowflake, dbt)\n- Proficient in at least one statistical programming language (Python or R)\n- Strong business acumen and the ability to connect analysis to product strategy, roadmap tradeoffs, and business outcomes\n- Demonstrated curiosity about AI tools and emerging technologies, with a track record of applying them to accelerate analysis, improve rigor, or expand the reach of data science work\n- Strong expertise in experimental design, causal inference, and statistical methods - you know how to draw defensible conclusions from imperfect data\n- 7+ years of experience as a data scientist or analyst, with a track record of driving business impact through statistical analysis, experimentation, and predictive modeling\n- Excellent communication and data storytelling skills - you can translate complex findings into clear narratives that influence strategy and decisions at all levels of the organization\n- Fluent in SQL","description_format":"text","description_chars":3634,"description_truncated":false,"requirements":{"experience_years_min":7,"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":["Human Resources","Payroll Services"],"lifecycle":[{"event":"open","at":"2026-10-14T00:40:12Z"},{"event":"close","at":"2026-10-14T07:10:37Z"}],"visa":[{"country":"US","licensed_sponsor":true,"evidence":"H-1B filings in 12 months: 11 · green card filings: 2","filings_12m":11,"filings_prev_12m":18,"green_card_filings_12m":2,"median_offered_wage_usd":170192,"route":null,"cap_exempt":false,"checked_at":"2026-10-03T21:08:04+00:00","sources":["US Department of Labor: LCA disclosure data (H-1B, H-1B1, E-3)","US Department of Labor: PERM disclosure data (green cards)"],"filings_for_role_12m":0}],"liveness":null,"pay":{"stated_usd_annual":214000,"is_top_pay":true},"html_url":"https://alion.io/job/justworks-senior-data-scientist","json_url":"https://alion.io/job/justworks-senior-data-scientist.json","meta":{"generated_at":"2026-10-15T00:48:24Z","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":933,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-16T00:00:00Z"}},"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":3396},"rest":"https://alion.io/mcp/rest/get_company?id=3396"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fjustworks-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%2Fjustworks-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%2Fjustworks-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/justworks-senior-data-scientist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fjustworks-senior-data-scientist"}]}
