Roles & ResponsibilitiesRole Summary
The AI Engineer is responsible for designing, building, and operationalizing scalable AI/ML solutions across the full lifecycle—from problem framing and data preparation to model development, deployment, and monitoring. This role collaborates closely with multiple teams to deliver measurable impact using machine learning, deep learning, generative AI, and MLOps best practices.
Key Responsibilities

Solution Design & Problem Framing
Translate business challenges into ML problem statements with clear success metrics.
Evaluate and select appropriate algorithms (traditional ML, deep learning, LLMs).
Produce design artifacts: architecture, data flow, risks, and guardrails.

Data Engineering & Feature Development
Build and maintain data pipelines (batch/real-time) using Python, SQL, PySpark.
Engineer reusable features and ensure data quality, validation, and governance.
Work with data owners to define contracts and manage PII responsibly.

Model Development & Evaluation
Develop, train, and tune models using frameworks such as scikit-learn, XGBoost, PyTorch.
Perform evaluation, error analysis, fairness checks, and experiment tracking (MLflow).
Ensure reproducibility, versioning, and documentation.

MLOps & Productionization
Containerize and deploy models using CI/CD pipelines (Azure DevOps, GitHub Actions).
Implement monitoring for model drift, latency, and cost; create auto-retraining workflows.
Optimize inference for scale (quantization, distillation, vector indexing).

Generative AI & LLM Integration
Build Retrieval-Augmented Generation (RAG) workflows: chunking, embeddings, vector stores.
Design prompts, evaluation frameworks, safety guardrails, and hallucination controls.
Assess LLMs using metrics for factuality, consistency, and performance.

Collaboration, Documentation & Leadership
Work cross-functionally with product, engineering, and compliance teams.
Write technical documents, runbooks, model cards, and architecture diagrams.
Mentor junior engineers; participate in technical reviews and hiring.


Required Technical Skills

Languages: Python (proficient), SQL; familiarity with PySpark or Scala a plus.
ML/DL: scikit-learn, XGBoost/LightGBM, PyTorch/TensorFlow, MLflow.
Cloud/Platforms: Azure ML, AWS SageMaker, or Databricks.
Data Tools: Pandas, Spark, Delta/Parquet, Great Expectations (or equivalent).
MLOps Stack: Docker, Kubernetes, FastAPI, CI/CD, model registries.
GenAI Stack: LangChain/LlamaIndex (or equivalent agent frameworks), FAISS/pgvector, Azure OpenAI/OpenAI/HF.
