Job Title

AVP - Lead Data Scientist (Overall 12+ years of professional experience)

Role Description

We are seeking an AVP - Lead Data Scientist with deep expertise in applied machine learning andGenerative AI/LLM solutions, strong Python skills, and a track record of delivering models and experimentation into production-grade applications/platforms. This role will lead thedata science strategy, modeling approach, evaluation standards, and experimentation disciplinefor GenAI and ML use cases, partnering closely with AI/ML engineers, data engineering, and application/platform teams (including agentic application development). Candidates with experience shaping end-to-end solutions (problem framing → modeling → evaluation → productionization → monitoring) and influencing architecture/design decisions are preferred.

Roles & Responsibilities

• Lead end-to-end data science delivery across multiple initiatives:problem framing, hypothesis design, feature strategy, model development, evaluation, and iteration.
• Drive development and improvement ofML and GenAI solutions, including model selection, fine-tuning approaches (where applicable), and performance optimization.
• Define and implementevaluation frameworksfor ML/LLM systems (offline metrics, test sets, error taxonomy, regression testing, human evaluation loops).
• Provide DS leadership forRAG-based solutions(retrieval strategy, grounding, relevance quality, context optimization) and partner with engineering on implementation.
• Guide data science contributions toagentic applications: tool selection logic, planning/routing heuristics, guardrails, and measurable quality outcomes.
• Partner with AI/ML engineers and software/platform teams to transition models into production: packaging, APIs, monitoring, and continuous improvement.
• Collaborate with data engineers to define data requirements, data quality checks, preprocessing utilities, and feature engineering pipelines.
• Use cloud platforms (Azure preferred / AWS) to run experiments and support scalable training/inference using managed services where appropriate.
• Establish best practices for experiment tracking, reproducibility, documentation, and model governance.
• Communicate insights and recommendations to stakeholders translate business goals into measurable ML/GenAI objectives and technical plans.
• Mentor senior/junior data scientists lead reviews for modeling approach, evaluation design, and experiment results.
• Stay current on ML/GenAI advancements and recommend pragmatic adoption aligned with business and platform constraints.

Core/Must have skills

• BS or Master's in Computer Science, Computer Information Systems, Engineering, Mathematics, or related field.
• 12+ years overall experience with8+ years hands-on Pythonfor applied data science/ML development.
• Strong knowledge ofmachine learning algorithms, model development lifecycle, feature engineering, and evaluation methodologies.
• Practical experience withLLMs/GenAI(e.g., GPT/BERT-class models), including prompt-based approaches and/or fine-tuning concepts.
• Strong understanding ofLLM evaluationand quality measurement ability to set up repeatable experimentation and regression testing.
• Experience partnering with engineering teams toproductionize models(deployment patterns, monitoring, iterative improvements).
• Hands-on exposure toAzure or AWSML/AI services and tooling.
• Excellent stakeholder management, communication, and cross-functional collaboration skills.

Good to have skills

• Experience withprompt engineering, prompt routing strategies, and guardrails for enterprise LLM applications.
• Experience withDatabricksand/orAzure Machine Learningfor scalable experimentation and pipelines.
• Knowledge ofagent frameworks/patterns(e.g., orchestration, tool/function calling, memory) and how to measure agent quality.
• Familiarity with Docker/containerization and basic deployment concepts for DS assets.
• Experience with model risk, compliance considerations, and privacy/security patterns for GenAI (PII handling, prompt injection awareness).
