Lead Data scientist

Job Description

Job title:

Lead Data scientist

Your role:

The Lead Data Scientistarchitects, builds, and runsproduction-gradeMachine Learning and Generative AI systemsu2014owning the full lifecycle from model development to scalable cloud deployment and ongoing performance monitoring. In addition, the role partners with commercial stakeholders translate market/customer data into decision-ready insights and AI-enabled analytics solutions that drive measurable outcomes

Operating with a builder and translator mindset, the individual rapidly develops MVP analytics solutions, leverages AI to accelerate insight generation, and ensures strong product engineering fundamentals, data quality, and governance. The role plays a critical part in establishing a single source of truth for performance management across markets and channels while elevating analytics maturity from descriptive reporting to predictive and insight-led decision making.

Key Responsibilities

1) ML & Deep Learning Model Development

• Design, train, and optimizeML models for prediction, classification, ranking, time-series forecasting, anomaly detection, NLP, and recommendation use cases.

• Build robust experimentation workflows (train/validation strategy, ablations, error analysis) and improve model quality through iterative tuning.

• Ensure reproducibility and maintainability through clean code practices, versioning, and automated testing.

2) GenAI Engineering (LLMs, RAG / MCP / fine-tuning, Agents)

• Build enterprise-grade LLM applications using RAG (retrieval-augmented generation), MCP, and fine-tuning approaches: chunking strategies, embedding generation, hybrid retrieval, reranking, prompt templates, and citation/attribution patterns.

• Develop LLM applications with tool use/function calling patterns and agentic workflows where appropriate.

• Implement systematic evaluation: curated eval sets, prompt regression tests, hallucination checks, retrieval quality metrics, and automated quality gates.

3) ML & LLM Operations: Productionization, Deployment & Monitoring

• Deploy and operate real-time and batch inference solutions on Azure using managed endpoints and/or containerized serving.

• Build CI/CD for ML systems: automated packaging, container builds, model validation tests, staged rollouts, and rollback strategies.

• Establish lifecycle management: model registry/versioning, lineage, promotion workflows, and release governance.

• Implement observability: latency, throughput, cost, drift signals, data quality checks, alerts, and performance degradation monitoring.

4) Pipeline Orchestration & Automation (Train u2192 Deploy)

• Build standardized ML pipelines for training, evaluation, and deployment using orchestration tools (cloud-native pipelines and/or platform tools).

• Automate dataset/version management, feature generation, scheduled retraining triggers, and approval workflows.

• Define repeatable patterns for scalable experimentation and reliable production delivery.

5) Analytics Products, Dashboards & Data Governance

• Own key analytics outputs as products (dashboards, reusable datasets, internal tools), continuously improving them based on usage patterns and performance gaps.

• Build and automate dashboards and analytical components using scalable SQL logic, Python transformations, and reusable modules.

• Act as owner for critical commercial/syndicated datasets (e.g., GfK, Circana, Nielsen or equivalent): definitions, assumptions, and limitations, ensuring transparent logic and trust in outputs.

• Partner with data engineering/IT to ensure data quality, harmonization, and governance through strong validation and reconciliation practices.

6) Stakeholder Partnership & Decision Support (Lightweight, High Impact)

• Serve as trusted analytics thought partner to senior stakeholders (e.g., BU leadership, Sales, Marketing, Finance), shaping problem statements and aligning on success metrics.

• Translate complex analytics into clear recommendations with a decision-oriented storyline (u201Cso-what / now-whatu201D), tailored for leadership forums and reviews.

• Support performance reviews, planning cycles, and high-priority ad-hoc requests with speed, rigor, and confidence proactively challenge assumptions with fact-based insights.

7) Responsible AI, Security, and Risk Controls (GenAI-ready)

• Implement guardrails: prompt injection defenses, sensitive data protections, output validation, and secure tool execution patterns.

• Apply responsible AI practices: transparent evaluation criteria, auditability, and risk controls aligned to enterprise needs.

8) Technical Leadership (Lead-level Expectations)

• Set engineering standards for DS/ML codebases: design docs, code review practices, testing discipline, and production readiness checklists.

• Mentor data scientists/ML engineers on modeling, GenAI engineering, and MLOps best practices.

• Lead architectural decisions across modeling approaches, retrieval stack, serving patterns, and evaluation strategy.

Core Skills & Competencies

Must-have (Technical)

• Strong Python (production-quality coding) and solid CS fundamentals strong SQL for data access and validation.

• Depth in ML: Traditional ML exposure and at least one deep learning framework (PyTorch/TensorFlow), with strong understanding of metrics and failure modes.

• GenAI implementation: RAG / MCP / fine-tuning, embeddings/vector search, prompt orchestration, evaluation harnesses, and LLM application patterns.

• Production deployment experience on AWS or Azure (model/LLM app deployment, API serving, scaling, monitoring).

• MLOps tooling: experiment tracking, model registry, CI/CD, and pipeline orchestration (e.g., MLflow or equivalent patterns).

Good-to-have (Business + Influence)

• Strong business acumen and ability to connect disparate data points into compelling narratives that influence senior stakeholders.

• Builder/MVP mindsetu2014rapid prototyping and iterating based on stakeholder feedback while maintaining data quality and governance

Education Requirements

• Bacheloru2019s degree in engineering, Computer Science, Statistics, Economics, Mathematics, or a related quantitative field.

• Masteru2019s degree preferred (e.g., Data Analytics, Business Analytics, Applied Statistics, Economics, AI, or MBA with strong analytics focus).

• Continuous learning mindset expected, with demonstrated upskilling in advanced analytics, AI, or data engineering concepts (formal or informal).

Note: This role values applied problem-solving and business impact over purely academic specialization.

You're the right fit if:

• Proven track record of owning end-to-end analytics domains, not just contributing to isolated analyses or consuming pre-built reports.

• 7u201312+ years in hands-on Data Science / ML Engineering with multiple production deployments owned end-to-end.

• Demonstrated ability to take solutions from experimentation u2192 production (reproducible pipelines, deployment to managed endpoints/container platforms, monitoring + iterative improvement).

• Strong GenAI delivery record: shipped RAG/MCP/fine-tunedLLM applications with measurable quality controls, safety measures, and operational readiness.

• Experience operating in complex, matrixed environments and partnering with senior stakeholders to drive insight-led decision making

• Hands-on exposure to AI-enabled analytics, including the use of GenAI tools (e.g., ChatGPT, Claude, or similar) to accelerate insight generation, analysis, or productivity.

• Strong experience partnering with senior business stakeholders (BU leaders, Sales, Marketing, Finance), influencing decisions through insight-led storytelling.
