About the Role As a Senior Software Engineer on the Developer Platform team, you will design and scale Workday’s core services platform. You will be product‑oriented, take ownership of the full lifecycle of applications, and lead the architecture of critical distributed subsystems. Your role spans backend microservices, frontend experiences, and the integration of AI‑driven engineering tools. What You’ll Do Design, build, and evolve secure, scalable microservices and intuitive frontend experiences that power mission‑critical product features. Own major platform initiatives end‑to‑end, translating ambiguous technical and product concepts into clean, functional software. Champion best practices in domain‑driven design, API contract management, testing, observability, and architectural modernization to reduce technical debt. Leverage AI‑assisted engineering tools and autonomous coding agents to accelerate delivery and raise baseline quality. Lead and unblock a small, high‑velocity team (1–3 developers), providing technical guidance, mentorship, and constructive code reviews. Basic Qualifications Bachelor’s or Master’s degree in Computer Science, Engineering, or equivalent practical experience. 8+ years of software engineering with a focus on backend microservice architectures and distributed systems. 5+ years of experience with Java, Kotlin, or Go. 5+ years of experience with AWS (preferred), GCP, or Azure, including S3, Lambda, EC2, CloudFront, SQS, SNS, DynamoDB, and MySQL. Experience with Docker and Kubernetes. 2+ years of full‑stack experience building modern frontend UIs (React, Angular, or Vue). 1+ year of experience with modern architectural standards such as Model Context Protocol (MCP). Expert‑level AI‑augmented development (e.g., Cursor, Claude Code, GitHub Copilot) with the ability to direct, prompt, audit, and validate agentic‑generated code. Other Qualifications Deep proficiency in Java or Kotlin with strong command of design patterns, distributed systems, and high‑availability architecture. Expertise in API development and contract management, including familiarity with modern protocols such as MCP. Strong full‑stack competency with modern frontend frameworks (React/TypeScript), algorithmic thinking, and a track record of translating complex requirements into scalable code. Service ownership mindset: end‑to‑end accountability for operational health, test automation, CI/CD pipelines, and cloud‑native observability. Hands‑on experience integrating AI capabilities into software products and using AI‑augmented workflows to accelerate delivery. Proven ability to lead cloud infrastructure cost optimization initiatives across large‑scale AWS/GCP deployments. Strong collaborator and communicator, able to partner with PMs, designers, and engineers to break down features into sprint tasks and articulate technical tradeoffs to both technical and non‑technical stakeholders. Experience with Developer Platforms, DevTools, or core engineering platforms is a plus.
