Workday Pay Transparency Statement ## Description We are looking for Software Development Engineers to help build the AI Infrastructure Development Platform: the platform that enables teams to develop, deploy, and operate AI agents in production. In this role, you will design and implement backend services, systems, and tooling that support the Software Development Life Cycle (SDLC) for AI applications. You'll work on problems spanning distributed systems, orchestration, and developer experience, helping teams reliably build, test, and scale AI-powered workflows. This is a great opportunity for an engineer who enjoys building production systems, solving complex technical problems, and working at the intersection of platform engineering and AI., * Build and maintain services and tooling that support agent deployment, testing, and lifecycle management within the CI/CD pipeline. * Develop systems for workflow coordination, state management, and tool integration in the context of development and operations. * Write high-quality, maintainable code in Python to power platform capabilities and APIs. * Deploy and operate services on Kubernetes, ensuring reliability and scalability. * Contribute to systems for observability, logging, tracing, and debugging of distributed workflows in development and production. * Improve system performance across latency, throughput, and fault tolerance. * Build internal tools and APIs that improve the developer experience for teams using the platform. * Collaborate with engineers, product managers, and AI teams to deliver production-ready solutions and development infrastructure. * Participate in design discussions and contribute to system architecture and technical decisions., 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.
