About the Team
We're an AI platform organization. We build the platform other engineering teams use to develop, evaluate, and deploy AI systems, and we build production applications on top of it — agentic solutions alongside a broad range of classical ML.
The work spans the full applied-AI stack: model and agent development, evaluation infrastructure, serving performance and cost, and the pipelines that get it all into an enterprise product. Our systems run against real customer data, so correctness, reliability, and observability matter as much as capability.
We're hiring at senior software engineer to have someone own a significant surface area end to end — design through delivery and operation.
About the Role
As a Senior Software Development Engineer on the AI Foundations team, you will be primarily responsible for designing, building, and operating the software systems that host, run, and scale AI-powered applications at Workday.

Work closely with machine learning engineers to write and maintain production-grade backend services that power AI-driven capabilities and agent applications
Design and implement APIs and service integrations that enable AI capabilities to be consumed across Workday products and platforms
Build and operate data ingestion and ETL pipelines that support AI application workflows
Apply distributed systems principles in production to address scalability, concurrency, fault tolerance, and performance challenges
Ensure systems meet enterprise requirements for security, privacy, robustness, and compliance
Own services through their full lifecycle, including deployment, monitoring, debugging, and ongoing operational improvements
What you'll do
- Design, build, and operate core services and infrastructure for AI development, evaluation, and deployment
- Own a significant surface area end to end, including production health and on-call
- Turn open-ended problems into scoped, sequenced work — for yourself and for others
- Raise the bar through design and code review, and mentor engineers on the team
- Partner with product, research, and infrastructure teams on tradeoffs and roadmap

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