Data Scientist, Platform AI Squad, Group Data Office (AVP/VP)

About the Role

As a Data Scientist, Platform AI Squad, Group Data Office, you will design, optimize, and maintain the enterprise cloud infrastructure and software frameworks powering Enterprise AI across the bank. Operating at the intersection of AI application engineering, high-performance inference, and cloud platform engineering, you will work across Agentic AI frameworks and applications, low-latency LLM inference stacks leveraging hybrid-cloud services, and platform-level MLOps/DevOps pipelines.

In this role, you will establish standardized MLOps processes, optimize LLM inference, architect and build end-to-end AI solutions, maintain production pipelines, and drive enterprise AI engineering best practices.

Key Responsibilities

1. Agentic AI Platforms & Frameworks

• Build and scale multi-agent orchestration frameworks (LangGraph, AutoGen, CrewAI) integrated with AWS.
• Design and implement reusable, enterprise-grade agentic platform components and applications.
• Implement function-calling harnesses and modern protocols (Model Context Protocol / MCP, A2A) connecting LLMs to databases (e.g., AWS Aurora, DynamoDB), vector stores, and enterprise APIs.
• Integrate managed cloud services (Amazon Bedrock Agents & Knowledge Bases) alongside custom open-source agent frameworks.
• Deploy automated evaluation pipelines (RAGAS, DeepEval, Bedrock Guardrails) to validate tool-calling precision, hallucination rates, and prompt safety before production release.

2. LLM Inference Optimization & Model Lifecycle

• Deploy and maintain low-latency LLM serving engines (vLLM, TensorRT-LLM, TGI, SGLang) across on-premises GPU clusters and cloud infrastructure.
• Establish GPU capacity planning, utilization tracking, monitoring, and budgeting processes.
• Oversee automated model versioning, artifact storage, and metadata tracking using MLflow or Amazon SageMaker Model Registry.
• Integrate foundation models via Amazon Bedrock and Amazon SageMaker AI for serverless scaling and hybrid workload routing.
• Package models into production-ready microservices supporting REST/gRPC APIs, batch processing, and streaming inference.
• Implement PagedAttention, Dynamic Batching, KV Cache offloading, and Speculative Decoding to minimize Time-to-First-Token (TTFT) and maximize token throughput.

3. AWS Cloud Architecture, MLOps & Daily DevOps Support

• Provide daily operational support for MLOps platforms, ensuring high availability (99.9%+ SLA), cluster stability, and rapid incident resolution.
• Build and maintain automated CI/CD workflows (GitHub Actions, GitLab CI, Bitbucket, Jenkins, AWS CodePipeline, ArgoCD) for model testing, containerization, feature store syncing, and release management.
• Provision multi-tenant enterprise infrastructure using Terraform, AWS CloudFormation/CDK, and Helm on Kubernetes (EKS).
• Configure telemetry (AWS CloudWatch, Prometheus, Grafana) for GPU tracking, latency SLAs, token costs, and data/model drift monitoring.

Experience & Background

• Education: Bachelor's, Master's, or Ph.D. in Computer Science, Data Science, Artificial Intelligence, or a quantitative discipline.
• Work Experience:
  • AVP Level (4+ years): Hands-on experience building LLM applications, microservices, containerized AWS deployments (EKS/Docker), and managing daily MLOps operations, have experience to drive a project from 0 -1.
  • VP Level (8+ years): Demonstrated track record architecting production AI platforms, LLM serving stacks, and multi-agent harnesses at enterprise scale, while leading platform engineering practices, have team leading experience.

Technical Skills

• AWS Cloud & AI Services: Core experience with Amazon Bedrock, SageMaker AI, EKS, EC2 GPU instances, S3, IAM, CloudWatch, and PrivateLink.
• Languages & Core AI Frameworks: Strong proficiency in Python. Deep hands-on experience with LangChain/LangGraph and LlamaIndex.
• Agentic Frameworks & Protocols: Practical experience with agentic workflows and protoco
