Senior Principal AI Engineer

Job Description

Vertex is seeking a   Senior   Principal AI Engineer   to design, build, and optimize the shared platform capabilities that power AI-enabled products and intelligent workflows across the enterprise.   Working within the Agentic AI Platform team, this   role will focus on delivering production-grade platform services for model integration, prompt and workflow orchestration, evaluation, observability, performance optimization, and agent lifecycle management.

A key focus of this role will be enabling a build/bring-your-own-agents capability within the Agentic AI Platform, allowing teams across Vertex to create, integrate, customize, and operationalize their own agents using shared platform standards, tooling, and governance controls.

The ideal candidate combines strong software engineering fundamentals with deep experience in applied AI systems. This individual will be comfortable operating across rapid experimentation and engineering rigor, translating emerging AI capabilities into scalable, reliable, secure, and reusable platform components. The Senior Principal AI Engineer will play a critical leadership role in accelerating AI adoption across Vertex by enabling product teams to build and deploy AI solutions faster and more effectively.

Key Responsibilities

Build/bring-your-own-agents capability (primary focus): the frameworks, SDKs, templates, interfaces, and guardrails that let teams across Vertex create, integrate, customize, and operationalize their own agents on shared platform standards

Platform services: model integration, prompt and workflow orchestration, tool use, memory patterns, and agentic task coordination that other teams build against

Agent lifecycle and quality: registration, configuration, testing, deployment, versioning, monitoring, and retirement, plus the evaluation and benchmarking frameworks behind them

Developer experience: self-service onboarding, documentation, reference implementations, and enablement resources that shorten the path from idea to production

Standards and technical leadership: platform APIs, service contracts, architecture patterns, and the engineering practices that keep custom agents safe, reliable, and supportable

Architect and develop shared AI/agentic platform services that support enterprise AI products and internal workflows

Design and implement a build/bring-your-own-agents capability that enables teams to create, register, integrate, deploy, and manage their own agents within the enterprise agentic platform

Establish reusable frameworks, SDKs, templates, interfaces, and guardrails that standardize how custom agents are built and onboarded onto the platform

Own the   developer experience   for the platform, delivering intuitive self-service onboarding, SDKs, CLIs, sandbox environments, reference implementations, and clear documentation that let builders move from idea to production quickly

Define agent lifecycle capabilities including agent registration, configuration, testing, deployment, monitoring, versioning, and retirement

Build and maintain robust integrations with foundation models, model gateways, APIs, enterprise tools, and related AI infrastructure

Design and implement systems for prompt orchestration, workflow execution, tool use, memory patterns, and agentic task coordination

Develop reusable frameworks and services for evaluation, benchmarking, and validation of AI model, agent, and workflow performance

Establish platform capabilities for observability, monitoring, tracing, logging, and alerting across AI workloads and autonomous agent interactions

Optimize platform performance, scalability, latency, reliability, and cost efficiency for production AI and agentic systems

Partner with product, data, engineering, security, and architecture teams to enable enterprise-ready AI solutions

Translate prototypes and experimental concepts into hardened, maintainable, production-grade services

Define engineering standards, best practices, and design patterns for AI platform development and deployment

Support governance, risk management, and responsible AI practices through measurable controls, policy enforcement, and technical safeguards for agent behavior

Drive platform adoption by creating reusable components, documentation, onboarding patterns, and developer enablement resources

Mentor engineers and provide technical leadership across AI platform initiatives

Evaluate emerging tools, frameworks, and architectural patterns in generative AI and agentic systems to inform platform strategy

Required Qualifications

Bachelor’s degree in Computer Science , Software Engineering, Machine Learning, Data Engineering, or a related technical field; advanced degree preferred

Significant industry experience in software engineering, machine learning engineering, or AI platform development, including experience in senior or principal-level technical roles

Proven track record designing and delivering production-scale AI or ML platforms

Strong experience building distributed systems, APIs, microservices, and cloud-native applications

Demonstrated experience operationalizing machine learning, generative AI, or agent-based solutions in enterprise environments

Experience designing extensible platform capabilities that enable internal teams to build or integrate custom applications, tools, or services

Deep understanding of software engineering best practices including testing, CI/CD, version control, code review, and system reliability

Deep understanding of AI-native software engineering practices and experience establishing standards, governance, and best practices for the responsible use of AI coding assistants and software engineering agents across engineering teams

Experience defining architecture, standards, and reusable services for large-scale enterprise environments

Experience leading complex technical initiatives and influencing architecture across cross-functional teams

Strong communication skills with the ability to explain complex technical concepts to varied audiences

Experience balancing experimentation speed with production engineering discipline, security, and maintainability

Technical Skills Required
