Senior Integration Engineer (Workday & MuleSoft/Workato/AWS)

The Challenge

As an Integration Engineer you will work on a cross-functional team across the client’s Business Systems such as Finance, Accounting, HR, Data Engineering, Lead to Cash, and internal product engineering organizations. You will have a unique opportunity to shape how our systems communicate by designing, building, testing, and supporting enterprise-grade integrations between Workday and our broader application landscape (HCM, Payroll, Financials, and third-party vendors). In this hands-on role, you will bridge technical and functional teams, write clean integration logic, and ensure reliable, secure data flows in production.

Your Mission

• Design, build, and test inbound and outbound integrations using Workday Studio, Enterprise Interface Builders (EIBs), and Core Connectors.
• Develop and maintain high-quality (MuleSoft and Workato) integration systems that are both scalable and global at their core, including REST and SOAP web services, scheduled orchestration frameworks, and custom XML/JSON mappings.
• Partner with business stakeholders to translate requirements into scalable integration design whether they exist in Workday using calculated fields and custom reports (RaaS) or externally in AWS or Workato.
• Understand existing Mulesoft integrations and work with team members to convert them to Workato or AWS.
• Build serverless, event-driven integrations on AWS using services such as Lambda, API Gateway, Step Functions, EventBridge, SQS/SNS, and S3, with secure credential management through Secrets Manager and IAM.
• Triage production integration failures, monitor system health, perform root-cause analysis, and apply durable fixes with an emphasis on sustainable long-term solutions.
• Maintain clean technical documentation, runbooks, and ISSG/security configurations, with all risks clearly noted and easily decipherable by end-users.

You Are

• Someone who can independently own complex integrations across Workday, MuleSoft/Workato, and AWS to deliver reliable, secure data flows in a challenging, dynamic environment.
• Bachelor’s degree in Computer Science, Information Systems, Engineering, or a related field (or equivalent experience).
• 4+ years of integration engineering experience, including 2+ years of hands-on Workday integration development and deployment in a production environment, with deep expertise in Workday Studio, EIBs, and Core Connectors.
• Proven track record of delivering integration projects end-to-end, from requirements gathering through production support.
• Experienced developing inbound and outbound integrations and workflows with both iPaaS platforms MuleSoft and Workato.
• Hands-on experience building integrations on AWS (Lambda, API Gateway, Step Functions, EventBridge, SQS/SNS).
• Strong proficiency in XSLT, XML, JSON, and Web Services (REST/SOAP).
• Experience with Workday Report Writer, Calculated Fields, and security/ISU/ISSG setup.
• 3+ years of experience in Java or Python development, including debugging against APIs.
• Knowledgeable in security surrounding integrations – X509, PGP, SSH.
• Familiarity with Git version control (GitHub/GitKraken) and Agile/Scrum methodologies.
• Organized and analytical, adept at working in a team environment, able to follow and implement a project schedule, with a continuous improvement mindset and the ability to handle multiple priorities concurrently.
• An excellent communicator, self-starting and energetic, capable of dealing with ambiguity and rapidly changing priorities, and skilled at collaborating cross-functionally with geo-distributed stakeholders at all levels both internally and externally.

Extra Awesome

• Workday Pro Integrations or Extend certification.
• Workato Integration Developer certification or others
• AWS certification (e.g., Developer or Solutions Architect – Associate).
• Experience migrating integrations between platforms (e.g., MuleSoft to Workato or AWS).
• Experience using AI in an integration engineering context.
