About this opportunity

Job Description

Vertex is seeking a   Senior   Principal AI Engineer to define and build the foundational enterprise AI platform that powers intelligent applications across the enterprise. This role will lead the design and implementation of scalable, secure, and reusable capabilities for agentic AI, with a strong focus on retrieval-augmented generation (RAG), orchestration frameworks, evaluation systems, and platform architecture.

In addition to building out the core platform, this   engineer   will own the vision   and day-to-day operations of   a centralized AI   Gateway   / Control Plane /   Control Tower   that enables agent monitoring, observability, policy enforcement, governance, and operational controls across AI solutions at Vertex. This is a highly strategic and hands-on role for an experienced AI   engineer   who is excited to shape enterprise AI architecture, standards, and long-term technical direction.

Key Responsibilities

Agentic AI platform :   the shared architecture, services, and reusable capabilities that make it faster and safer to build AI-powered applications across Vertex

AI Control Tower operations: standing up and running the centralized control plane for agent monitoring, observability, telemetry, policy enforcement, guardrails, usage analytics, and auditability

Own the strategy, architecture, implementation, and day-to-day operation of the centralized AI Gateway / Control Tower as the enterprise control point for model access, routing, governance, cost management, and operational oversight

Intelligent model routing, provider abstraction, fallback, failover, rate limiting, and workload optimization across approved models

AI FinOps, including token and consumption visibility, budgeting, chargeback/ showback , cost allocation, forecasting, and model-cost optimization

Centralized guardrails for content safety, prompt-injection defense, data-loss prevention, sensitive-data handling, and responsible AI policy enforcement

Identity, access, security, privacy, regulatory compliance, and lifecycle governance controls for models, agents, tools, and AI interactions

End-to-end observability, telemetry, quality monitoring, latency and reliability metrics, incident response, and operational health management

Usage analytics, immutable audit trails, policy evidence, risk reporting, and executive-level transparency across the enterprise AI estate

Model onboarding, approval, versioning, deprecation, resiliency, capacity management, and third-party provider governance

Retrieval and knowledge systems: RAG pipelines, vector search, document retrieval, and the grounding patterns that make enterprise content usable by agents

Agent lifecycle and quality: deployment, versioning, evaluation frameworks, reliability measurement, and continuous improvement of agents in production

Standards and technical leadership: platform APIs, service contracts, architecture patterns, and the engineering practices other teams build against

Define the technical vision, architecture, and roadmap for Vertex’s enterprise agentic AI platform

Design and build reusable platform services that accelerate development of safe, reliable, and scalable AI-powered applications

Lead architecture and implementation for RAG pipelines, knowledge retrieval systems, prompt workflows, tool use, and agent orchestration

Establish core frameworks for agent lifecycle management, including deployment, monitoring, observability, evaluation, and continuous improvement

Develop scalable infrastructure patterns for enterprise AI workloads, including model integration, data access, and orchestration services

Partner closely with product, engineering, data, security, and UX teams to deliver common AI platform capabilities that support multiple use cases across Vertex

Establish best practices for AI reliability, evaluation, safety, and performance measurement

Drive technical standards for platform APIs, service contracts, architecture patterns, and reusable components

Evaluate emerging technologies, frameworks, and vendors in the AI/agentic ecosystem and make strategic recommendations

Mentor engineers and influence cross-functional technical teams through architectural leadership and hands-on guidance

Ensure platform solutions align with enterprise requirements for scalability, resilience, security, and maintainability

Contribute to Vertex’s long-term AI strategy by identifying opportunities to expand platform capabilities and increase enterprise adoption
