Principal Technical Architect – AI, Data Platforms & Cyber Security

Role: Senior Principal Technical Architect – AI, Data Platforms & Cyber Security

Location: Princeton, NJ & NYC, NY (Hybrid)

Job Description: Principal Technical Architect – AI, Data Platforms & Cyber Security

Position Title: Principal Technical Architect – AI Systems, Data Platforms & Cyber Security

Department: Enterprise Architecture / Data, AI & Security Engineering

Experience Level: 15+ Years (Executive / Principal Level)

Role Overview

1. We are seeking a visionary and hands-on Principal Technical Architect to lead the architecture, design, security, and strategic evolution of our Enterprise Data Platforms and Multi-Agent GenAI Systems.
2. In this role, you will bridge the gap between complex enterprise data engineering, modern cloud architecture, cutting-edge Generative AI applications, and enterprise cybersecurity controls.
3. You will design zero-touch automated data observability solutions, multi-agent AI pipelines, zero-trust data access patterns, and enterprise-wide GenAI adoption frameworks.
4. The ideal candidate brings a deep technical background in Databricks, cloud platforms, Python, contract-driven LLM architectures, threat modeling for AI systems, and proven enterprise leadership in scaling and securing AI solutions across the organization.

Key Responsibilities:

1. AI Systems & Multi-Agent Architecture

1. Architect Multi-Agent AI Pipelines: Design end-to-end, LLM-powered multi-agent frameworks (deterministic + generative) using Pydantic contracts, asynchronous Python, and provider-agnostic model integration (e.g., OpenAI SDK, Databricks Model Serving).
2. AI Tooling & Scaffolding: Build graph-based execution builders, dynamic YAML rules engines, capability registry patterns, and structured diagnostic retry mechanisms for LLM agents.
3. Human-in-the-Loop Integration: Implement validation and curation layers that enable user DAG editing, schema validation, and error repair before scaffold generation.

2. AI Security, Risk & Guardrails

1. LLM Threat Modeling & Abuse Prevention: Lead abuse-case modeling, prompt injection defense, jailbreak mitigation, and red-teaming strategies for LLM agents and RAG architectures.
2. Output Guardrails & Data Protection: Implement payload masking, custom SQL validation layers, row-count caps, and automated PII/PCI detection to prevent data exfiltration via AI interfaces.
3. Identity & Access Governance: Architect hybrid identity flows (OAuth 2.0, Okta/Entra ID), Service Principal access patterns, and automated token lifecycle/rotation management (e.g., Delta Sharing tokens).

3. Enterprise Data Platforms & Observability

1. Databricks Estate Architecture: Lead large-scale data platform migrations, estate auto-discovery, and governance automation across Databricks workspaces (Unity Catalog, Workflows, Jobs API, Delta Lake, Delta Sharing).
2. Data Governance & Zero-Trust Access: Enforce fine-grained authorization models including Row-Level Security (RLS), dynamic column masking, and centralized data classification in Unity Catalog.
3. Data Quality & Observability Frameworks: Design automated, multi-tiered data quality verification platforms capable of real-time incident detection, automated table onboarding, and continuous file freshness tracking.
4. Platform Governance & FinOps: Oversee multi-cloud cost governance (AWS, Azure, Google Cloud Platform), resource optimization, and infrastructure governance to maximize ROI while maintaining compliance.

4. Enterprise GenAI Adoption & Governance

a)     Org-Wide Transformation: Define and execute adoption strategies for developer AI tooling (e.g., GitHub Copilot, custom LLM assistants) and establish measurement frameworks for code quality, productivity gains, and ROI.

b)     Enablement & Standards: Conduct technical workshops, build best-practices documentation, create reusable architectural patterns, and mentor engineering teams across divisions.

c)     Compliance & Security Auditing: Oversee access recertification, SIEM logging/auditing mechanisms, and regulatory compliance (e.g., regional data residency and vendor risk governance).

Required Qualifications & Technical Expertise

Professional Experience

1. 10+ years of progressive experience in software engineering, enterprise data platforms, AI systems, and technical/security architecture within high-volume enterprise environments.
2. Proven track record of architecting scalable solutions adopted across large organizations while maintaining high standards of data protection and zero-trust security.
3. Experience leading enterprise-wide technology adoption programs, platform migrations, and security governance frameworks.
