At Airbnb, driven by our philosophy of "High Tech, Human Touch," we are looking for a Senior Workday Integration Engineer to be the technical representative for critical integration initiatives within BizTech. You will help shape our integration strategy and technical roadmap, influencing architectural decisions that enable seamless HR data flows across our global employee population.
What You'll Do
- Architect, design, build, and maintain inbound and outbound integrations using Workday Studio, Core Connectors, EIBs, Document Transforms, and RaaS API endpoints.
- Develop integrations against Workday Web Services (WWS), including WSDL interpretation, web service versioning, and request/response handling for both SOAP and REST endpoints.
- Build and expose RaaS API endpoints for internal consumers and external vendor partners; provide hands-on guidance to vendors building against Airbnb's API specifications.
- Handle high-volume data scenarios — payroll runs, benefits open enrollment, and global rollouts — with appropriate performance and scalability design.
- Build and maintain advanced Custom Reports and Calculated Fields to shape data for integration consumption.
- Work within and around the Business Process Framework — understanding how business process events trigger integration flows.
- Leverage Core Connectors and Business Processes to configure outbound integrations for benefits, payroll, and HR change events.
- Serve as subject matter expert on current and upcoming Workday capabilities, including Workday AI Features, Orchestrate, and Extend.
- Maintain integrations across Workday's semi-annual release cycle: proactively assess release notes for impact, test in sandbox, and deploy updates to production.
- Own SLAs for your integration portfolio; build and maintain monitoring, alerting, retry logic, idempotency strategies, and runbooks.
- Implement PII handling, audit controls, and data reconciliation strategies that meet compliance requirements across multiple jurisdictions (GDPR, India PDPB, SOC 2).
- Enforce data security protocols: PGP, SSH, SFTP, HTTPS, OAuth 2.0, SAML, WS-Security.
- Manage tenant deployment strategy: sandbox → production promotion, version control of integration artifacts via Git, and rollback planning.
- Provide advanced technical leadership on integration design decisions, influencing cross-domain solutions across BizTech and partner teams.
- Translate complex functional and business requirements into sound technical integration designs, clearly evaluating constraints and trade-offs for stakeholders.
- Partner with Employee Experience, Recruiting, Payroll, and IT Security teams to gather requirements and deliver solutions.
- Collaborate with adjacent middleware integration teams (e.g., MuleSoft) building integrations against Workday's exposed APIs.
- Write thorough Integration Design Documents, technical specifications, and operational runbooks maintainable by others.
- Conduct code reviews and contribute to integration standards, reusable patterns, and governance practices across Talent Systems.
- Proactively identify risks, communicate trade-offs, and manage stakeholder expectations when constraints require it.
What We're Looking For
- Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field (or equivalent experience).
- 10+ years of industry experience in software development or systems integration.
- 6+ years of hands-on Workday integration development experience, covering the full lifecycle: requirements → design → build → testing → go-live → post-production support.
- Demonstrated, hands-on proficiency in Workday Studio: complex multi-step integrations, sub-integrations, custom error handling and fault frameworks, XSLT transformations.
- Demonstrated, hands-on proficiency in Core Connectors: worker data, business process events, payroll and benefits outbound connectors.
- Demonstrated, hands-on proficiency in Enterprise Interface Builder (EIBs): including knowledge of where EIBs are appropriate and where their limitations require escalation to Studio.
- Demonstrated, hands-on proficiency in Document Transforms: payload mapping and field-level transformation logic.
- Demonstrated, hands-on proficiency in RaaS (Report-as-a-Service): advanced report design, calculated fields, and endpoint exposure.
- Demonstrated, hands-on proficiency in Workday Web Services (WWS): WSDL reading, SOAP/REST web service calls, versioning, and error response handling.
- Expertise building advanced Custom Reports and Calculated Fields to support integration logic.
- Working knowledge of the Business Process Framework and how events trigger and interact with integration flows.
- Expert proficiency in XSLT, XML, and JSON; proficiency in Java, XTT, and ETV sufficient for Studio development.
- Experience integrating Workday with downstream SaaS systems: payroll processors, benefits carriers, ATS platforms, identity providers, and HCM downstream systems.
- Familiarity with Workday functional configuration across HCM, Benefits, Payroll, Security, and Time & Absence — enough to independently navigate a tenant and diagnose upstream data issues.
- Strong knowledge of data security and compliance requirements: PGP, SFTP, OAuth 2.0, SAML, WS-Security, PII handling.
- Experience managing integrations across Workday's semi-annual release cycle, including impact assessment and sandbox testing.
- Git-based version control and experience with structured deployment and change management processes.
- Experience working in an Agile/Scrum environment.
- Exceptional written and verbal communication skills; able to write clear IDDs and runbooks and present technical trade-offs to non-technical stakeholders.
- Proven track record as a technical leader influencing architecture decisions across cross-functional teams.
Nice to Have
- Workday Pro Certification in Integrations (highly valued).
- Experience with Workday payroll interfaces (PECI, PICOF) and third-party payroll providers.
- Experience with Workday Orchestrate and Extend capabilities.
- Experience with CloudPay or Global Payroll Connect (GPC).
- Experience with middleware/iPaaS platforms (MuleSoft, Boomi, Workato) and the architectural judgment to know when middleware is appropriate vs. native Workday integration.
- Experience supporting global, multi-country production environments.
- Knowledge of GDPR, India PDPB, or SOC 2 compliance requirements in the context of HR data flows.
Technical Stack
- Workday Studio, Core Connectors, Enterprise Interface Builder (EIBs), Document Transforms, RaaS API endpoints, Workday Web Services (WWS)
