ABOUT THE TEAM
Admin Central is building the future of how administrators work across Workday—turning a fragmented patchwork of tools and disconnected AI into a single, unified experience.
Within Admin Central, the Business Process Optimize team powers the underlying platform infrastructure. You’ll build mission-critical distributed systems, high-availability usage pipelines, and event-driven data flows across global product regions to ensure enterprise billing integrity at scale. If you're excited to build from scratch, move fast, and transform how thousands of admins work every day, come join us!
ABOUT THE ROLE
As a Principal Machine Learning Engineer on the Business Process Optimize team within Admin Central, you will lead the architecture and implementation of Workday’s next-generation AI platforms and autonomous agent frameworks. You’ll sit at the intersection of machine learning, event-driven data systems, and enterprise platform engineering—transforming cutting-edge AI research into production-ready, highly reliable systems handling tens of millions of daily requests for over 100+ Tier-0 enterprise tenants.
In this hands-on, high-impact role, you will design the ML infrastructure, multi-agent orchestration layers, and high-availability usage pipelines that power enterprise-grade decision-making, usage tracking, and billing integrity across international regions.
Your Primary Focus:
- Agentic AI & Orchestration: Design, implement, and maintain advanced agentic capabilities, including tool calling, multi-agent workflows, long-range planning, reasoning frameworks, and human-in-the-loop integrations.
- Scalable ML Infrastructure: Build secure, high-throughput REST services and event-driven data pipelines using Python, Kubernetes, and cloud-native tech. Architect multi-tenant runtimes that deliver fast, low-latency inference to millions of global users.
- MLOps & Enterprise Reliability: Establish end-to-end MLOps standards—including CI/CD automation, observability, evaluation frameworks, model monitoring, and privacy/anonymization guardrails—ensuring systems are explainable, secure, and production-resilient.
- Technical & Strategic Leadership: Partner closely with software engineers, Product Managers, Data Engineering, SRE, and Legal/Compliance stakeholders to turn ambiguous business needs into scalable technical designs and long-term data-governance strategies.
BASIC QUALIFICATIONS
- 12+ years in ML development and R&D leadership, including 8+ years with advanced ML methodologies, distributed frameworks, and cloud-based platforms — designing complex, scalable, production-grade ML systems.
- 6+ years building and hosting scalable ML services, microservices, and high-throughput data pipelines in production using Java, Go, Scala, or Python.
- 4+ years working with LLMs, generative AI, RAG pipelines, and autonomous agent frameworks for real-world enterprise applications.
OTHER QUALIFICATIONS
- Data Processing & Pipelines: Expert in high-throughput streaming (Kafka), real-time feature extraction (Spark/Flink), and distributed columnar storage (ClickHouse, Iceberg) to architect large-scale ML pipelines.
- AI/ML Expertise: Deep knowledge of deep learning, LLM orchestration, RAG, and agentic systems — applying ML algorithms and Model-Based Design (including MCP integrations and tool-use frameworks) to multi-agent coordination, intent classification, and workflow optimization.
- Data Analysis & Feature Engineering: Proven ability to lead EDA on multi-tenant agentic workflows to shape data strategy, paired with mastery of high-dimensional embeddings, vector database management, and data isolation.
- Model Lifecycle: Proven ability to lead model building, fine-tuning, and deployment of domain-specific foundation models — including Kubernetes/Docker deployment, automated CI/CD retraining, and managing drift/latency at scale.
- Technical Stack: Mastery of Python and the ML ecosystem (PyTorch, TensorFlow, LangChain, LangSmith, LlamaIndex, NumPy, Pandas, Scikit-learn), with strong experience deploying production systems on PostgreSQL, Redis, Kafka, and cloud infrastructure (AWS/GCP/Azure).
- Team Leadership: Exceptional collaboration and mentoring skills — technically leading cross-functional pods, driving sprint planning, and translating technical/governance decisions for executives.
- Education: Bachelor's in Computer Science, Data Science, Statistics, Mathematics, Engineering, or related field (or equivalent experience); Master's or PhD strongly preferred.

OUR APPROACH TO FLEXIBLE WORK
With Flex Work, we’re combining the best of both worlds: in-person time and remote. Our approach enables our teams to deepen connections, maintain a strong community, and do their best work.

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.
Pursuant to applicable Fair Chance law, Workday will consider for employment qualified applicants with arrest and conviction records.

Search Principal Jobs in CaliforniaPrincipal Jobs in California: Frequently Asked Questions
Which companies sponsor visas for principals in California?
Large technology employers account for the majority of principal-level visa sponsorships in California. Companies such as Google, Apple, Meta, Amazon, Salesforce, Adobe, and Intuit have consistent H-1B filing histories for senior individual contributor and principal roles. Semiconductor and biotech firms concentrated in Silicon Valley and San Diego, including Qualcomm and Illumina, also sponsor at this level with regularity.
Which visa types are most common for principal roles in California?
The H-1B is the most common visa category for principal roles in California, as these positions typically require a bachelor's degree or higher in a specific specialty field. Candidates with extraordinary ability in their domain may also qualify for the O-1A. Senior professionals transferring within a multinational organization may be eligible for the L-1A or L-1B, depending on whether the role is managerial or involves specialized knowledge.
Which cities in California have the most principal sponsorship jobs?
The San Francisco Bay Area, including San Jose, Sunnyvale, and Mountain View, concentrates the highest volume of principal-level visa sponsorship activity in California, driven by its technology sector density. Los Angeles follows, with sponsorship activity spread across entertainment technology, fintech, and aerospace. San Diego is a notable hub for principal roles in biotech, defense technology, and semiconductor companies.
How to find principal visa sponsorship jobs in California?
Migrate Mate is built specifically for international candidates seeking visa sponsorship employment in the United States. You can filter directly for principal roles in California to see verified sponsorship-eligible openings from employers with active H-1B or other visa filing histories. Migrate Mate surfaces jobs from companies that have demonstrated willingness to sponsor, helping you focus your search on realistic opportunities rather than sifting through postings that don't support international candidates.
Are there state-specific considerations for principal visa sponsorship roles in California?
California's prevailing wage requirements under Department of Labor rules apply to H-1B petitions, and principal-level roles in high-cost metros like San Francisco and San Jose typically fall into the upper wage tiers. California also enforces strict employee classification laws, which can affect how sponsoring employers structure employment agreements. Candidates should be aware that employer legal and HR teams in California are generally experienced with sponsorship processes given the state's high volume of international hires.
What is the prevailing wage for sponsored principal jobs in California?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
