Full Job Description

Your work days are brighter here.

At Workday, it all began with a conversation over breakfast. When our founders met at a sunny California diner, they came up with an idea to revolutionize the enterprise software market.

And ever since, the happiness, development, and contribution of every Workmate is central to who we are. Our Workmates believe a healthy employee-centric, collaborative culture is the essential mix of ingredients for success in business. That's why we look after our people, communities and the planet while still being profitable. Feel encouraged to shine, however that manifests: you don't need to hide who you are. You can feel the energy and the passion, it's what makes us unique. Inspired to make a brighter work day for all and transform with us to the next stage of our growth journey? Bring your brightest version of you and have a brighter work day here.

About the Role

In this software engineering role, you will work with machine learning engineers to build, test, and deploy agentic solutions. You will be part of a fast-paced team with a startup-like mentality.

Your primary focus will be to:

  • Lead technical initiatives from conception to production

  • Build and deploy Python and Spark-based ETL pipelines for collecting, joining, transforming, and loading data used for model training and inference

  • Build and deploy secure, restful web services in Python and Kubernetes that activate agents and invoke actions

  • Design and implement a multi-tenant runtime architecture that enables fast inference, scales to millions of users, and integrates with existing Workday components

  • Build React-based interactive prototypes/demos for showcasing and evaluating the agents

You will also:

  • Collaborate with multi-functional teams, including MLEs, product managers, and UX designers

  • Take ownership for finding creative solutions that move projects forward

  • Write clean, maintainable, and testable code following standard methodologies in software engineering, including automation, observability, and scalability.

  • Conduct code reviews, participate in design discussions, and engage in collaborative team activities like hackathons and knowledge-sharing sessions.

About You

Basic Qualifications:

  • 8 or more years of experience with production-level Software Development

  • 4 or more years of experience in Python.

  • 4 or more years of experience building scalable ETL pipelines

  • 4 or more years of experience deploying production services to cloud platforms (e.g., AWS, Azure, GCP) and using containerization technologies (e.g., Docker, Kubernetes).

Other Qualifications:

  • Experience with full stack engineering, including front-end frameworks (e.g. React), database technologies, and API development

  • Strong understanding of scalable architecture and performance optimization for web applications.

  • Algorithmic Thinking and a proven track record of designing, implementing, and analyzing algorithms

  • Proven experience building flexible and reusable software components.

  • Experience developing Code Testing strategies with an emphasis on understanding various testing methodologies

  • Strong sense of ownership and delivery of finished products. A balance between craftsmanship and the need to ship products to customers.

  • Excellent communication and collaboration skills, with a strong focus on Team Collaboration and customer impact.

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.

Workday is an Equal Opportunity Employer including individuals with disabilities and protected veterans.
