About the Team

About the Role

In this senior individual-contributor role as a Senior Machine Learning Engineer, you will bring strong applied ML expertise to a high-performing team of distributed-systems engineers, contributing to technical strategy and automation across Workday's administration platform. Working closely with Engineering leads and Product Managers, you will help shape technical approach, build and deploy production-grade ML systems, and support fellow engineers while partnering with core platform teams to integrate machine learning into Workday's administrative systems.

Drawing on your solid industry background, you will work effectively within a collaborative ecosystem, turning technical capabilities into measurable business impact for Workday customers.

Key Responsibilities

• Design, build, and productionize machine learning models and pipelines that integrate with Workday's platform-level systems.
• Apply and help refine best practices for ML engineering within the team, including model development, evaluation, deployment, and monitoring.
• Partner with distributed-systems engineers to ensure ML solutions scale reliably across Workday's multi-tenant architecture.
• Own significant pieces of end-to-end ML lifecycle work — from problem framing and data strategy through model training, deployment, and performance monitoring in production.
• Collaborate cross-functionally with product management, data engineering, and platform teams to identify opportunities for ML-driven automation and intelligence.
• Provide technical guidance and code/design review to other engineers on ML system design and implementation.
• Evaluate new tools, frameworks, and techniques to help keep the team's ML practices current and effective.
• Contribute to the technical roadmap for ML capabilities within the Adoption team.
• Design and deploy Generative AI capabilities and Large Language Model (LLM) applications

About You

Basic Qualifications

• Substantial professional experience in machine learning engineering, applied ML, or a closely related discipline, with a track record of shipping ML systems to production.
• Strong software engineering fundamentals, including experience building and operating distributed, production-grade systems.
• Proficiency with common ML frameworks and languages (e.g., Python, PyTorch/TensorFlow) and with MLOps practices (model versioning, CI/CD for ML, monitoring).
• Ability to work with a good degree of independence — contributing to technical direction, participating in architecture discussions, and driving projects from concept to delivery.
• Demonstrated technical leadership and collaboration skills through experience with cross-team initiatives, establishing technical standards, and mentoring junior and mid-level engineers.
• Demonstrated experience designing and developing with Generative AI technologies and LLM integration in production systems.

Other Qualifications

• 7+ years of experience working within large-scale, multi-tenant SaaS platforms.
• Background in applying ML to enterprise/administrative platform problems (e.g., anomaly detection, automation, intelligent configuration).
• Hands-on familiarity with LLM orchestration frameworks (preferably LangChain) and AI agentic architectures.
• Experience with cloud infrastructure and large-scale data processing systems.
• Advanced degree (MS/PhD) in Computer Science, Machine Learning, or a related field, or equivalent practical experience.

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.
