Sr. Software Development Engineer - Distributed Systems ( Java/ Kotlin)

As a Senior Software Engineer, you will play a key role in designing and scaling Workday’s Developer core services platform. We are looking for a product-minded engineer with a strong sense of end to end ownership -someone who can wear multiple hats, thrive in ambiguous environments, and act as an owner to drive core platform initiatives from conception to completion. You will lead the architecture of critical distributed subsystems, drive technical execution within the team, and collaborate closely with cross-functional partners to deliver robust solutions.

This role requires deep hands-on expertise in distributed systems and microservices, along with a proven track record of translating complex product requirements into scalable code. You are not just building software to a specification; you possess a deep curiosity about how your components integrate into the broader business ecosystem, a relentless focus on customer adoption, and mastery of AI-driven engineering tools to drastically reduce delivery cycles. You will tackle sophisticated technical challenges, champion engineering best practices, and help mentor team members to ensure high-velocity, reliable delivery.

What You’ll Do

• Design, build, and evolve secure, scalable microservices and intuitive frontend experiences that power mission-critical product features with strong performance and reliability.
• Own major platform initiatives end-to-end translating ambiguous technical and product concepts into clean, functional software with clear accountability.
• Champion best practices in domain-driven design, API contract management, testing, observability, and architectural modernization to reduce technical debt and elevate code quality.
• Leverage AI-assisted engineering tools and autonomous coding agents (e.g., Cursor, Claude Code) as an expert power-user 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 to foster a culture of continuous learning.

• Bachelor’s or Master’s degree in Computer Science, Engineering, or equivalent practical experience.
• 8+ years of software engineering with a strong focus on backend microservice architectures and distributed systems.
• 5+ years of experience in each of the following:
• Programming: Java, Kotlin, or Go.
• Cloud Platforms: AWS (preferred), GCP, or Azure, including expertise with S3, Lambda, EC2, CloudFront, SQS, SNS, DynamoDB, and MySQL.
• Containerization/Orchestration: Docker and Kubernetes.
• 2+ years of full-stack experience building modern frontend UIs (e.g., React, Angular, or Vue).
• 1+ year of experience with:
• Modern architectural standards (e.g., Model Context Protocol/MCP).
• Expert-level AI-augmented development (e.g., Cursor, Claude Code, GitHub Copilot), with a demonstrated ability to direct, prompt, audit, and validate agentic-generated code.

Other Qualifications

• Deep backend proficiency in Java or Kotlin, with strong command of design patterns, distributed systems, and high-availability architecture.
• Expert API development and contract management skills, including familiarity with modern protocols (e.g., MCP) to support a spec-driven development approach.
• 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, balancing performance with financial scalability.
• Strong collaborator and communicator - able to partner with PMs, designers, and engineers to break down features into sprint tasks and clearly articulate technical tradeoffs to both technical and non-technical stakeholders.
• Experience with Developer Platforms, DevTools, or core engineering platforms is a plus.

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.
