About the role

This is a critical, hands-on role at the heart of product and client delivery, reporting directly to the Head of ML. You'll work across three pillars: running ML Ops processes, refining LLM/ML models with human feedback and performance analysis, and transforming conversation data into repeatable, business-ready insights for clients and ongoing model innovation.

As a Machine Learning Data Engineer, you'll combine technical skills in Python, SQL, BI, and ML Ops with analytical storytelling that bridges data and decision-making. To succeed, you'll bring an analytical, meticulous, and bias-aware mindset, communicate clearly with non-technical stakeholders, collaborate closely with product and engineering teams, and demonstrate adaptability, initiative, and strong time management in a distributed environment.

• Insight & research
• Perform hypothesis-led analysis over large datasets to uncover trends, drivers, and client-ready narratives
• Build and maintain industry benchmark datasets that power reports and dashboards, with tight definitions and version control
• Deliver clear, actionable Power BI reports for clients and internal stakeholders; maintain stand-alone reports in third-party tools where required
• ML Ops lifecycle (operate & improve)
• Own performance dashboards, operational processes, model registry/version control, and experiment tracking
• Monitor drift and bias, validate improvements, and manage safe deployment/rollback
• Keep the feature store up to date, ensuring training data lineage and reproducibility
• Partner on productised evaluations (automated tests, acceptance thresholds) and bias mitigation aligned to policy
• Product & data engineering
• Specify, design, and implement dashboards and reports, integrating with portals and APIs
• Collaborate with platform/DB teams on robust data integration and storage patterns across PostgreSQL/NoSQL and data lake assets
• Support Copilot auto-report creation, ensuring source-of-truth metrics and governance
• Client analysis
• Run client-specific studies to test hypotheses and meet project goals
• Present findings clearly to non-technical audiences
  

• Bachelor's degree in Data Science, Computer Science, Statistics, Mathematics, or a related field
• 3–4 years of experience in data analysis, BI, or ML analytics
• Python (pandas, NumPy, scikit-learn): 3+ years, with strong SQL skills. (R is an advantage.)
• Power BI (data models, DAX): 2+ years, including Power Query (M) and advanced Excel (pivots, complex formulas)
• Data warehousing & ETL: 2+ years, including statistics for A/B testing, sampling, and bias checks
• Databases: PostgreSQL, DynamoDB (or equivalent)
• Familiarity with LLM concepts and evaluation methods
• Exposure to cloud data services (AWS/Azure) and ML Ops tooling (feature store, experiment tracker, model registry, monitoring)
  

• Healthcare or life sciences exposure
• Relevant BI/analytics certifications (e.g., Microsoft Data Analyst)
• Experience with advanced ML Ops practices
  

• Fixed Shifts: 12:00 PM - 9:30 PM IST (Summer) | 1:00 PM - 10:30 PM IST (Winter)
• No Weekend Work: Real work-life balance, not just words
• Day 1 Benefits: Laptop and full medical insurance provided
