Software Development Engineer

We’re obsessed with making hard work pay off, for our people, our customers, and the world around us. As a Fortune 500 company and a leading AI platform for managing people, money, and agents, we’re shaping the future of work so teams can reach their potential and focus on what matters most. The minute you join, you’ll feel it. Not just in the products we build, but in how we show up for each other.

Our culture is rooted in integrity, empathy, and shared enthusiasm. We’re in this together, tackling big challenges with bold ideas and genuine care. We look for curious minds and courageous collaborators who bring sun-drenched optimism and drive. Whether you're building smarter solutions, supporting customers, or creating a space where everyone belongs, you’ll do meaningful work with Workmates who’ve got your back.

In return, we’ll give you the trust to take risks, the tools to grow, the skills to develop and the support of a company invested in you for the long haul. So, if you want to inspire a brighter work day for everyone, including yourself, you’ve found a match in Workday, and we hope to be a match for you too.

In this team you will work closely with engineers, product managers, and other cross-functional peers to turn business goals into well-scoped, high-quality engineering work. Within our team we value a team first mentality, lifting each other up, and ensuring that we are delivering the product features that our customers will truly value.

As a Full Stack Developer on the Developer Tooling team, you will help shape the tools that define how developers build on Workday. You will work across the stack — from React-based interfaces to Node.js backend services — delivering features for App Builder, the Workday CLI, and adjacent developer-facing products. Your work will directly impact how easily developers can adopt, extend, and build on the Workday platform.

You will partner closely with peers, product owners, and designers to plan, build, test, and deliver high-quality software that helps our developer community succeed. This role is a strong fit for someone who enjoys full-stack ownership, takes pride in well-tested and maintainable code, and is energized by building tools that other developers rely on every day.

• Contribute to and deliver new and existing features for App Builder, the CLI, and other developer tools, with a focus on scalability, performance, and a high-quality developer experience.
• Collaborate with peers, product owners, and designers to scope, plan, and ship features in an agile environment.
• Discover and troubleshoot issues within the existing architecture and codebase, identifying opportunities for improvement and keeping the platform healthy and forward-looking.
• Support developer-facing documentation, onboarding flows, and tooling improvements that make the platform easier to adopt and extend.
• Contribute to release planning by evaluating the effort, risk, and priority of planned features.
• Help improve team productivity by contributing to process improvements and engineering best practices

• 4+ years of professional experience building and supporting multi-tier or full stack web software
• 4+ years of experience in Node.js for backend service development
• 4+ years experience developing RESTful APIs and manage complex third-party API integrations
