As a Principal/Senior Software Engineer, Agentic UX in Agent Factory, you’ll help build the conversational AI experience and ambient capabilities that bring Workday’s agents to life. You are an AI-native builder, not a pure frontend developer. You will own features end-to-end, connecting the agentic logic directly to the user interface. You don't just build UI; you orchestrate the agentic flows that power the UX. You’ll design and ship experiences that bridge the gap between AI capabilities and user intent. This role is about turning powerful technology into products people actually use: scalable, reliable systems that simplify complex business processes. You’ll collaborate closely with AI engineers, software engineers, product managers, and designers, ensuring that the interface is a seamless extension of the agent's reasoning. If you enjoy building real products and solving meaningful problems at the intersection of AI and human workflows, you'll feel right at home here.

Your responsibilities:

• Design and deliver intuitive conversational and agentic AI experiences, prioritizing seamless user interactions and thoughtful workflows.
• Shape how users experience AI reasoning by bridging the gap between powerful agent capabilities and clear, usable interfaces.
• Collaborate in an iterative, team-first environment that values strong engineering practices and continuous learning
• Share knowledge, mentor teammates, and help raise the technical bar across the pod 

• 12+ years of experience in software engineering
  7+ years experience with a web development framework (TypeScript/React, Python/FastAPI)
• 3+ years of experience building conversational or agentic AI applications
• 5+ years of experience leading projects or teams

• 8+ years of experience in software engineering
  5+ years experience with a web development framework (TypeScript/React, Python/FastAPI)
• 2+ years of experience building conversational or agentic AI applications

• Experience collaborating with product designers, or a demonstrated portfolio focusing on high-quality UX/UI design principles
• Experience building and operating SaaS products in cloud environments (AWS preferred)
• Familiarity with the tradeoffs and architecture of modern distributed systems
• Knowledge of software development best practices (DevOps, CI/CD, automated testing, observability)
• Hands-on experience with containerization technologies (Docker, Kubernetes)
• Familiarity with Elasticsearch
• Exposure to additional programming languages like Java (backend) and TypeScript (frontend/fullstack) is a plus
• Proven success working within fast-paced, agile environments and cross-functional teams
• Strong communication skills, with the ability to collaborate with both technical and non-technical partners
• Comfortable working with ambiguity and translating complex problems into clear, thoughtful solutions
• Committed to fostering an inclusive, team-oriented environment and contributing to a culture of continuous improvement
