About the Team

About the Role

As a Senior Software Development Engineer in Product Engineering, you will be a technical leader in designing and delivering high0throughput, low0latency APIs and frameworks that support Workday's next generation of products and agents. You will shape API design, drive performance and observability improvements, and coach and grow future senior engineers across the team.

You will:

• Lead design and implementation of APIs and platform features used by Product Engineering teams.
• Champion consistent API standards, patterns, and tooling that align with cross0org guidance while solving concrete product needs.
• Help Product Engineering teams expose capabilities via REST, GraphQL, and emerging integration patterns in a way that is friendly to agents and external consumers.

What you0ll do

• Lead end0to0end design and development of complex backend services and APIs.
• Drive consensus with product managers, architects, and partner teams to define clear, evolvable API contracts and data models, using OpenAPI and internal standards.
• Drive performance and scalability improvements, including latency optimization, capacity planning, and resiliency strategies for mission0critical product flows.
• Design and implement observability for product APIs (metrics, tracing, structured logging), and use data to drive technical decisions and SLOs.
• Collaborate on frameworks, tools, and patterns that make it simpler for other Product Engineering teams to define, publish, and maintain APIs.
• Work with data platform teams to define patterns for exposing data safely and efficiently to API and agent workflows.
• Provide technical leadership through design reviews, RFCs, spike investigations, and coaching junior engineers.
• Participate in and improve on0call and incident response processes; own root cause analysis and long0term remediation for significant issues.
• Act as a trusted technical partner to teams across Product Engineering, helping them make API and integration decisions.

About You

Basic Qualifications

• 8+ years experience in software development engineering, architecting, building, and scaling robust and efficient software systems.
• 5+ years experience in the following programming languages and technologies: TypeScript or Python. 
• Bachelor0s degree in Computer Science, Engineering, or related discipline, or equivalent practical experience.

Other Qualifications

• Strong ability in Algorithmic Thinking, including advanced data structures and algorithms such as graphs, concurrent data structures, and caching/eviction strategies, to design and optimize solutions for complex API orchestration, request routing, and high-throughput workloads.
• Solid experience with API Development, including REST, SOAP, and GraphQL, OpenAPI/Swagger-driven design, and experience in designing and building scalable, secure APIs and API integration patterns.
• Strong understanding of Code Testing methodologies, such as contract testing, performance testing, and system/integration testing, and experience with advanced testing tools or frameworks (e.g., JUnit, ScalaTest, Postman, Mockito, and coverage tools such as Jacoco or Scoverage).
• Strong understanding of Object-Oriented Design (OOD) principles like SOLID, domain-driven design concepts, and common architectural patterns (e.g., layered architecture, hexagonal architecture) and their application in designing scalable software architectures.
• Solid understanding of Software Development principles and advanced development methodologies such as continuous delivery, trunk-based development, and test-driven or behavior-driven development.
• Solid experience with Source Control Management (SCM) tools such as Git and advanced branching and merging strategies across multiple teams or services.
• Proven ability to lead Team Collaboration within a software development team and mentor junior and mid-level engineers through design reviews, technical guidance, and knowledge sharing.
• Strong skills in creating Technical Writing Documentation for comprehensive technical specifications, design documents, RFCs, and API and integration best-practice guides.
• Experience leveraging AI0assisted code generation and review tools (e.g., Cursor, Claude Code, GitHub Copilot) to improve development speed and quality.
• Exposure to MCP or similar models is a strong plus.

Our Approach to Flexible Work

With Flex Work, we0re 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 you0ll 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 2home office2 roles also have the opportunity to come together in our offices for important moments that matter.
