We make complex steps easier to navigate so business owners can focus on building what comes next.\nAbout the role:\nHelp shape how Bizee uses AI to reach and serve more entrepreneurs. As a Staff Applied Scientist, you’ll turn open-ended marketing questions into experiments, models and systems that improve acquisition, conversion and customer value. Your work will connect customer behavior and marketing decisions to measurable business results.\nThis is a hands-on role where you will define the scientific approach when the problem, available evidence or measures of success are unclear. You’ll investigate data, develop hypotheses, train and adapt models, design experiments, and work with engineers to bring successful solutions into production. You’ll decide which problems deserve investment and establish whether the work produces incremental value.\nWhat you will do:\nPartner with Marketing, Product and Engineering to identify valuable opportunities. Use customer and campaign data to challenge assumptions and translate open-ended problems into testable hypotheses and clear measures of business success.\n\nDevelop models and AI workflows for audience understanding, personalization, recommendations, campaign optimization and content generation. Choose applications based on their potential to improve customer and business outcomes.\n\nDesign controlled experiments to measure incremental improvements in conversion, efficiency and customer value. Use causal methods where randomization is impractical, explain their assumptions and distinguish incremental impact from attributed activity.\n\nTrain, adapt and evaluate models for marketing tasks. Compare statistical baselines, predictive models and LLM-based approaches, choosing methods based on evidence, data availability and operating cost.\n\nDevelop reliable training and evaluation datasets from customer, campaign and product data. Address missing data, selection bias and imbalance, prevent leakage, and respect privacy and consent requirements.\n\nCreate repeatable evaluations that connect model performance to marketing decisions and customer outcomes. For generative applications, test factual accuracy and failure cases using real Bizee examples, expert review and validated automated checks.\n\nOwn the scientific outcome through production and adoption, partnering with engineers to deploy and monitor models, diagnose performance changes, and improve latency and cost. Build feedback loops, track data and model versions, and define when to retrain, revise, or retire a solution.\n\nStay close to advances in AI and test the ideas that could improve Bizee’s products. Explain results and trade-offs clearly, document experiments, and share reusable methods that help the wider team make better decisions.\n\nWhat you need to have:\nA track record in applied science or machine learning of defining problems under uncertainty and taking models from experimentation into sustained business use.\n\nStrong foundations in statistics, machine learning and experimental design, with depth in causal inference, marketing science, personalization or optimization. You can identify bias, quantify uncertainty and explain what an experiment does and does not establish.\n\nHands-on experience developing models for customer behavior or marketing decisions, and applying AI to business workflows. You can choose between predictive models, experimentation and LLM-based approaches rather than treating one method as the default.\n\nStrong Python and SQL skills, experience with PyTorch or an equivalent framework, and the ability to write tested, maintainable code for reproducible experiments and production collaboration. Use AI tools to accelerate the work while verifying generated code and analysis.\n\nExperience with customer, product or campaign data and the limitations of observational evidence. You choose meaningful metrics, build representative evaluation sets and connect offline results to measured business impact.\n\nSound judgment about AI reliability and sensitive data. You can address unsupported outputs, prompt injection, and data exposure, and design traceable results with appropriate review and fallback behavior.\n\nThe autonomy to identify the problem when goals or evidence conflict, prioritize experiments and make practical trade-offs. You communicate clearly in English and establish methods and decisions that help colleagues work independently.\n\nA master’s or PhD in computer science, machine learning, statistics, or a related discipline, or equivalent experience demonstrating comparable scientific depth and delivery.\n\nNice to have:\nExperience with uplift modeling, recommendation systems, customer lifetime value, retention or budget optimization.\n\nExperience measuring campaign incrementality, working with advertising platforms or combining experimental and observational evidence.\n\nExperience with LLM-based personalization or content workflows, including evaluation of quality, factual accuracy and downstream customer outcomes.\n\nExperience operating ML systems in the cloud, or research and open-source contributions that demonstrate original thinking and practical impact.\n\nWhat we offer\nCompetitive compensation 34,000-47,000 PLN/month, stock options, and an annual bonus.\n\nA flexible benefits allowance to spend on what matters to you.\n\nAn office in the city center and a friendly, non-corporate atmosphere.\n\nReal ownership and the opportunity to make a visible impact.\n\nTech stack\nPython\nSQL\nPyTorch\nMachine Learning\nStatistics\nExperimental design","description_format":"text","description_chars":5730,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Legal Services","Accounting & Bookkeeping Services"],"lifecycle":[{"event":"open","at":"2026-10-30T14:25:00Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":11,"expected_fill_days":80,"reasons":["seen:11","velocity","win:early"],"computed_at":"2026-11-11T05:49:22Z"},"pay":{"stated_usd_annual":143556,"is_top_pay":false},"html_url":"https://alion.io/job/bizee-staff-applied-scientist-marketing","json_url":"https://alion.io/job/bizee-staff-applied-scientist-marketing.json","meta":{"generated_at":"2026-11-11T09:15:21Z","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":15241,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-12T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":3775},"rest":"https://alion.io/mcp/rest/get_company?id=3775"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbizee-staff-applied-scientist-marketing"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Fbizee-staff-applied-scientist-marketing"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Fbizee-staff-applied-scientist-marketing"},{"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/bizee-staff-applied-scientist-marketing\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbizee-staff-applied-scientist-marketing"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3526788}},{"tool":"search_jobs","arguments":{"company":"bizee.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3526788},"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.
