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 when we began to rise, one thing that really set us apart was our culture. A culture which was driven by our value of putting our people first. 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 Team

The Demand Capacity org is responsible for some of Workday’s core service orchestration technologies, which are deployed in Workday’s data center and public cloud environments. We provide orchestration solutions for other Workday development and operations teams, allowing us to reach the next level of scale.

Within this team, we are responsible for Workday’s optimized job processing platform, which performs some of the largest customer jobs in Workday. We are a core part of the Workday stack, working with concurrent and distributed systems to provide this background job processing platform for our internal and external customers.

Our platform performs critical processing and has a key role in the scalability of Workday’s platform. Our team is constantly innovating and evolving to build the next generation of critical Workday services.

About the Role

You will be responsible for designing, developing, troubleshooting and debugging scalable components, microservices and libraries using our technology stack, in a highly distributed environment. Among other technologies, we frequently use Scala, Akka, Gradle, AWS, Docker, Kubernetes, Jenkins, Kafka, and ZooKeeper.

The role will involve designing, developing and deploying critical production services, including working on highly concurrent transaction processing, distributed memory management, communication protocols, and algorithms for distributed processing.

About You

  • 9+ years of software engineering experience

  • 7+ years of distributed systems engineering experience in production, using Scala, or advanced Java/functional programming

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.
