The firm is recognised for its innovative approach, combining strategy and management consulting with data science and creativity. Sia Partners serves a diverse range of sectors, including energy, banking, healthcare, and technology, providing services to over 1,000 clients worldwide, including many Fortune 500 companies. With a strong emphasis on delivering tangible results and superior value, Sia Partners is committed to helping clients navigate the digital revolution and achieve transformation. The firm operates with a global presence, employing over 3,500 consultants across 48 locations in 20 countries\nOur Mumbai office was launched in 2024, marking an exciting new chapter for us. We’re building the team with people who are eager to shape something from the ground up - combining the agility and entrepreneurial energy of a startup with the backing and reach of a global brand.\n We are seeking a high-impact Senior Applied Data Scientist to join our team, where you will bridge the gap between advanced mathematical modeling and tangible business value. You will lead the design and implementation of sophisticated analytical solutions that solve complex problems for our global clients.\nIn this role, you will act as a strategic partner, working alongside consultants and engineers to translate business requirements into scalable data products. Unlike theoretical research, your focus will be applied-meaning you will be responsible for the end-to-end lifecycle of a model, from exploratory data analysis and feature engineering to production-grade deployment and monitoring.\nYou are not just a model builder; you are a problem solver who understands the \"why\" behind the data. You will navigate the nuances of predictive analytics, causal inference, and optimization to ensure our clients reach their transformation goals with precision and efficiency. We invest in your growth by providing access to cutting-edge tools, global centers of excellence, and a collaborative environment where technical rigor meets business strategy.\nKey Responsibilities\nEnd-to-End ML Development: Lead the discovery, development, and deployment of machine learning models (Regression, Classification, Clustering, Time-Series Forecasting) to solve industry-specific challenges.\n\nBusiness Translation: Work closely with stakeholders to identify high-value use cases and translate vague business problems into concrete technical roadmaps.\n\nData Engineering & Wrangling: Design and optimize data pipelines and feature stores, ensuring data quality and integrity across diverse environments (SQL, NoSQL, Data Lakes).\n\nAdvanced Analytics: Apply statistical rigor to experimental design, including A/B testing and causal inference, to validate the impact of business interventions.\n\nModel Productization: Partner with ML Engineers to implement MLOps best practices, including versioning, automated testing, and CI/CD for model deployment.\n\nScalable Architecture: Design robust, reusable analytical frameworks that can be scaled across different client engagements or internal Sia products.\n\nStakeholder Management: Communicate complex technical findings to non-technical executive audiences through compelling storytelling and data visualization.\n\nMentorship: Act as a technical lead, providing code reviews, architectural guidance, and mentorship to junior data scientists within the team.\n\nInnovation: Stay at the forefront of the field, evaluating and integrating emerging techniques in Deep Learning, Reinforcement Learning, or Optimization into the Sia toolkits.\n\nEducation: Master’s or PhD in a quantitative field such as Statistics, Mathematics, Computer Science, Economics, or Physics. \nExperience: 6+ years of professional experience in Data Science, with a proven track record of deploying models into production environments.\n\nCore Tech Stack: Expert-level proficiency in Python and its ecosystem (Pandas, NumPy, Scikit-Learn, XGBoost/LightGBM).\n\nDeep Learning: Hands-on experience with frameworks like PyTorch or TensorFlow.\n\nCloud Proficiency: Strong experience with cloud-based AI/ML platforms (AWS SageMaker, Azure ML, or Google Vertex AI).\n\nAI-Native Engineering Leadership: Experience managing teams that utilize Cursor, GitHub Copilot, or Claude Code as a core part of their daily workflow.\n\nData Manipulation: Advanced SQL skills and experience with big data technologies (Spark, Databricks, or Snowflake).\n\nDevOps/MLOps: Familiarity with Docker, Kubernetes, and Git-based workflows.\n\nConsulting Mindset: Excellent communication skills with the ability to navigate fast-paced, client-facing environments and manage multiple priorities.\n\nProblem Solving: A sharp analytical mind capable of breaking down complex, ambiguous problems into executable steps.\n\n What Success Looks Like\nThinks in systems, not just features.\n\nActs as a force multiplier for technical teams.\n\nDrives clarity in ambiguous technical situations.\n\nChooses long-term maintainability over short-term hacks.\n\nCommunicates complex ideas with precision and calm authority.\n\nLeads through technical credibility, not hierarchy.\n\nWhat We Offer\nOpportunity to lead cutting-edge AI projects in a global consulting environment.\n\nA dynamic and collaborative team environment with diverse projects.\n\nSia is an equal opportunity employer. All aspects of employment, including hiring, promotion, remuneration, or discipline, are based solely on performance, competence, conduct, or business needs.","description_format":"text","description_chars":5584,"description_truncated":false,"requirements":{"experience_years_min":6,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Management Consulting","AI Consulting & Integration","Analytics & BI Consulting"],"lifecycle":[{"event":"open","at":"2026-04-28T08:14:38Z"}],"visa":[],"liveness":{"score":4,"band":"cold","label":"Long shot","p_open":1,"p_active":0.151,"p_room":0.28,"age_days":171,"expected_fill_days":17,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/sia-senior-applied-data-scientist","json_url":"https://alion.io/job/sia-senior-applied-data-scientist.json","meta":{"generated_at":"2026-10-18T13:00:57Z","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":19303,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"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":5732},"rest":"https://alion.io/mcp/rest/get_company?id=5732"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsia-senior-applied-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%2Fsia-senior-applied-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%2Fsia-senior-applied-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/sia-senior-applied-data-scientist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsia-senior-applied-data-scientist"}]}
