In return, we’ll give you the trust to take risks, the tools to grow, the skills to develop and the support of a company invested in you for the long haul. So, if you want to inspire a brighter work day for everyone, including yourself, you’ve found a match in Workday, and we hope to be a match for you too.\nAbout the Team\nAt Workday, we believe AI agents will change how people and organizations work. The AI Platform organization builds the foundation that makes this possible: a secure, trusted, and scalable platform that Workday, our customers, and our partners use to build, run, and manage AI agents across some of the world's largest enterprises.Our team owns the full life of an agent. We govern how agents operate, help organizations build and measure them, and run them reliably at scale. We also manage the models that power them, route each request to the right model and provider, and provide the data and infrastructure underneath it all. Our customers trust Workday with their most sensitive people and financial data, and we hold our platform to that standard.\nAbout the Role\nThe Sr Principal is the most senior architecture leader in the AI Platform organization. This person owns the end-to-end architecture of the platform, defines the target state and the path to get there, and ensures every pillar builds toward a single, coherent design. The role draws on deep expertise in distributed systems, AI platforms, model engineering, and AI governance.\nThis is a senior individual contributor role with broad influence across the organization and the company. The successful candidate combines a clear architectural vision with the judgment to make lasting design decisions, the ability to align many teams around shared standards, and the communication skills to advise executives on technical strategy and investment.\nKey Accountabilities\nArchitecture Vision and Target State Define the long-term architecture vision and target state for the AI Platform, along with a practical roadmap to reach it. Ensure the architecture scales with Workday's growing agent ecosystem and stays aligned with business strategy.\nEnd-to-End Platform Architecture Own the overall architecture of the platform services that power agents and AI workloads, including runtimes, orchestration, routing, model management, and data infrastructure. Ensure these services fit together as one platform rather than separate systems.\nDistributed Systems Architecture Set the architectural patterns for the highly available, large-scale distributed systems that underpin the platform. Define the standards for reliability, performance, scalability, and fault tolerance.\nModel Architecture Define how models are integrated, served, evaluated, and optimized across the platform. Set direction on the architectural tradeoffs between model quality, performance, and cost, and ensure the platform can adopt new models quickly.\nCloud Architecture Define the cloud architecture across AWS and GCP, including multi-cloud design, the use of managed AI services, and cost-effective infrastructure patterns.\nAI Governance by Design Partner with the AI Governance and Sovereignty and Routing teams to build governance, security, privacy, and compliance into the architecture from the start. Ensure the platform supports auditability, responsible AI practices, and evolving regulatory requirements.\nArchitecture Standards and Governance Establish the reference architectures, design patterns, and architecture principles used across the organization. Lead the architecture review process and make or guide the critical design decisions that shape the platform.\nTechnology Evaluation Lead the evaluation of frameworks, platforms, and vendors, including build versus buy decisions. Ensure technology choices support the long-term architecture rather than short-term needs alone.\nCross-Pillar and Cross-Company Alignment Work across all pillars of the AI Platform organization, and with architects across Workday, to align on shared standards, resolve design conflicts, and ensure the platform integrates cleanly with Workday products.\nMentorship and Architecture Community Mentor architects and senior engineers, raise the design bar across the organization, and build a strong architecture community that can carry the vision forward.\nExecutive and External Influence Advise senior leadership on architecture strategy, technical risk, and investment tradeoffs.

Our approach enables our teams to deepen connections, maintain a strong community, and do their best work. We know that flexibility can take shape in many ways, so rather than a number of required days in-office each week, we simply spend at least half (50%) of our time each quarter in the office or in the field with our customers, prospects, and partners (depending on role). This means you'll have the freedom to create a flexible schedule that caters to your business, team, and personal needs, while being intentional to make the most of time spent together. Those in our remote \"home office\" roles also have the opportunity to come together in our offices for important moments that matter.\nPursuant to applicable Fair Chance law, Workday will consider for employment qualified applicants with arrest and conviction records.\nWorkday is an Equal Opportunity Employer including individuals with disabilities and protected veterans.\nWorkday is committed to providing reasonable accommodations for qualified individuals during our application process, in order to perform one or more essential functions of their job, as well as regarding the use of AI tools for employment decision-making to any degree.
