About the Role

We are looking for a Principal Consultant – AWS Data Platforms & Agentic AI to provide technical leadership in architecting, building and scaling next-generation enterprise Data and Agentic AI platforms.

This is a senior, hands-on technology leadership role requiring a rare combination of AWS Data architecture, Agentic AI expertise, engineering depth and executive presence.

You should be equally comfortable presenting a technology vision to CTOs and Managing Directors, defining Reference Architectures/HLDs/LLDs, leading technical workshops, and working directly with engineers to solve complex design, implementation, and performance issues.

This is not a strategy-only architecture role. Strong hands-on engineering capability is essential.

What You'll Do

• Lead architecture and engineering across Enterprise Data Platforms, Data Fabric, Data Products, Data Marketplace, BI and Agentic AI.
• Define scalable Lakehouse and Medallion Architecture patterns for data ingestion, processing, storage, governance and consumption.
• Architect Semantic Layers, Ontologies and Knowledge Graphs, including Amazon Neptune, to support analytics and Agentic AI.
• Design secure Agentic AI solutions using Amazon Bedrock AgentCore, Runtime, Gateway, Identity and Model Context Protocol (MCP).
• Establish patterns for Agent Identity, authentication, authorization, entitlements and governed agent-to-data access.
• Build identity and entitlement architecture across IAM, IAM Identity Center, Cognito, Lake Formation, S3, Glue, Athena and QuickSight.
• Design fine-grained data security, including RLS/CLS, data governance, guardrails and access observability.
• Industrialize Amazon QuickSight through dataset automation, SPICE optimization, security integration and platform governance.
• Establish enterprise Agent telemetry, observability and evaluation across agents, models, MCP/tool calls and data access.
• Define reusable Reference Architectures, HLDs, LLDs, engineering standards and implementation guardrails.
• Lead architecture workshops, technical deep-dives and design reviews with engineering and senior leadership.

Hands-On Engineering: This role requires someone who can go beyond architecture and work under the hood.

You will:

• Deep-dive into code, Spark jobs, data pipelines, SQL, APIs, IAM policies, infrastructure and platform configurations.
• Diagnose complex design, integration, production and performance issues.
• Optimize workloads across Spark/EMR, Athena, data pipelines and distributed services.
• Build POCs and reference implementations.
• Review solutions for scalability, security, resiliency and production readiness.
• Act as a senior technical escalation point and mentor architects and engineers.

Technology Expertise

Strong architecture and hands-on expertise across several of the following:

AWS Data & Analytics

• Amazon S3, AWS Lake Formation, Glue Data Catalog
• Amazon EMR on EC2 / EMR Serverless
• Spark / PySpark, Amazon Athena
• Lakehouse & Medallion Architecture
• Data Fabric, Data Products, Data Marketplace
• Data Pipelines, Metadata, Lineage & Data Governance

Agentic AI & Knowledge Platforms

• Amazon Bedrock / AgentCore
• AgentCore Runtime, Gateway & Identity
• Model Context Protocol (MCP)
• Semantic Layer & Ontologies
• Knowledge Graphs / Amazon Neptune
• Agent Identity, Entitlements & AI Guardrails

Integration, Security & Platform Engineering

• AWS IAM, IAM Identity Center, Cognito
• EventBridge, SNS, SQS, API Gateway, Lambda
• Terraform, AWS CloudFormation
• OpenTelemetry, CloudWatch, CloudTrail
• QuickSight / SPICE / RLS / CLS
• APIs, SQL, Angular and automation

What We're Looking For

• 12+ years across Data Platforms, Cloud Engineering, Platform Engineering or Architecture.
• 7+ years of strong AWS architecture and engineering experience.
• Proven experience architecting and building enterprise-scale Data Platforms on AWS.
• Deep understanding of Data Architecture, Medallion/Lakehouse, Data Products, Data Pipelines, Semantic Layers, metadata, governance and security.
• Strong understanding of GenAI and Agentic AI architectures and their integration with enterprise data.
• Experience taking solutions from architecture through implementation, production deployment and operationalization.
• Ability to troubleshoot complex code, data, integration and performance issues.
• Strong experience creating Reference Architectures, HLDs and LLDs.
• Ability to lead executive conversations as well as hands-on technical workshops.
• Financial Services or regulated-industry experience preferred.

Who Will Thrive in This Role

You are neither a strategy-only Enterprise Architect nor solely a delivery-focused Data Engineer.

You bring together:

Architecture Depth | Hands-on Engineering | Data & Agentic AI Vision | Executive Presence

You can articulate the future of Enterprise Data and Agentic AI to senior executives, translate that vision into detailed architecture, and then work alongside engineering teams to build, troubleshoot and optimize the solution.

You don't just define the architecture. You help build it and make it work in production.
