You will help build and ship the ML models and AI features that power our CDP platform, from customer segmentation and entity resolution to predictive analytics and LLM-powered automation. This is a hands-on engineering role : your work goes to production, not into notebooks that stay in research. You will learn by shipping, with mentorship from senior team members.\n\nKey Responsibilities : \n\n- Build and evaluate customer segmentation and clustering models (K-Means, DBSCAN, hierarchical) under guidance from senior team members\n\n- Support the development of entity resolution pipelines, using fuzzy matching, blocking and scoring to unify customer profiles across data sources\n\n- Train and evaluate predictive models for churn, conversion propensity and recommendations (logistic regression, Random Forest, XGBoost)\n\n- Help build LLM-powered features such as schema mapping, natural language querying and insight generation, using prompt engineering, embeddings and RAG pipelines through LLM APIs\n\n- Write SQL for feature engineering on analytical databases such as Snowflake or BigQuery\n\n- Wrap models in APIs (FastAPI) and help containerize and deploy them for batch and real-time inference\n\n- Contribute to monitoring, retraining and versioning of models in production\n\n- Work with data engineers to keep training data and feature pipelines clean and reliable\n\n- Document your experiments, assumptions and results clearly\n\nExperience and Skills : \n\n- Solid Python fundamentals, with working knowledge of Pandas, NumPy and scikit-learn\n\n- Good understanding of core ML concepts : supervised vs. unsupervised learning, overfitting, cross-validation, and precision/recall trade-offs\n\n- Comfortable with SQL beyond basic SELECT : joins, aggregations and an introduction to window functions\n\n- Basic understanding of text embeddings and semantic similarity\n\n- Familiarity with calling LLM APIs (Claude, OpenAI or similar) and writing effective prompts\n\n- Basic exposure to REST APIs (FastAPI or Flask) and Git\n\n- Strong problem-solving ability and a willingness to learn quickly\n\nGood to Have : \n\n- Hands-on exposure to XGBoost, or to Hugging Face transformers or sentence-transformers\n\n- Basic familiarity with Docker\n\n- Exposure to vector search (FAISS, Pinecone) or frameworks like LangChain\n\n- Familiarity with MLflow or other experiment tracking tools\n\n- Knowledge of fuzzy matching (Levenshtein, Jaro-Winkler) or record linkage\n\n- Academic projects, internships, Kaggle entries or GitHub work that show applied ML skills\n\n- Interest in customer analytics or MarTech\n\nQualifications : \n\n- B.E./B.Tech/M.Tech/M.Sc. in Computer Science, Data Science, Statistics, Mathematics or a related field\n\n- 0 - 1 year of relevant experience, including internships and substantial personal or academic projects\nSkills\nData Science, Python, Machine Learning, SQL, Generative AI, Data Scientist, Artificial Intelligence, LLM, Numpy, Pandas","description_format":"text","description_chars":3168,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Sales & Marketing"],"lifecycle":[{"event":"open","at":"2026-10-08T08:29:00Z"}],"visa":[],"liveness":{"score":84,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.836,"p_room":1,"age_days":4,"expected_fill_days":24,"reasons":["seen:4","win:early","comp:junior"],"computed_at":"2026-10-13T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/firsthive-data-science-engineer","json_url":"https://alion.io/job/firsthive-data-science-engineer.json","meta":{"generated_at":"2026-10-13T10:22:43Z","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":15815,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-14T00:00:00Z"}},"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":721213},"rest":"https://alion.io/mcp/rest/get_company?id=721213"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffirsthive-data-science-engineer"},{"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%2Ffirsthive-data-science-engineer"},{"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%2Ffirsthive-data-science-engineer"},{"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/firsthive-data-science-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffirsthive-data-science-engineer"}]}
