Staff Workday Integration Engineer

Integration Architecture & Technical Strategy

• Define and own Airbnb's Workday integration architecture standards, patterns, and governance frameworks
• Lead architectural decisions for complex, high-risk integration initiatives, including global rollouts, payroll runs, benefits open enrollment, and system migrations
• Evaluate and advise on build-vs-buy decisions, Workday-native-vs-middleware trade-offs, and long-term integration platform strategy
• Establish reusable integration design patterns, error handling frameworks, and observability standards adopted team-wide
• Anticipate platform evolution and architect integrations that accommodate Workday's semi-annual releases with minimal rework

Core Workday Integration Development

• Architect, design, build, and maintain complex inbound and outbound integrations using Workday Studio, Core Connectors, EIBs, Document Transforms, and RaaS API endpoints
• Develop integrations against Workday Web Services (WWS): WSDL interpretation, web service versioning, request/response handling for SOAP and REST
• Own design and delivery of high-volume integration scenarios: payroll runs, benefits open enrollment, global workforce changes, and multi-country rollouts
• Build and maintain advanced Custom Reports and Calculated Fields for integration consumption
• Work deeply within the Business Process Framework, understanding how process events trigger integration flows
• Maintain expert knowledge of Workday payroll interfaces (PECI, PICOF) and their interaction with third-party payroll providers
• Manage integration portfolio across Workday's semi-annual release cycle: assess release notes, lead sandbox testing, deploy to production with rigorous change controls

Workday Extend & Orchestrate

• Define and own Airbnb's adoption strategy for Workday Extend, including when Extend is the right tool versus Studio, EIB, or middleware
• Architect and build custom Workday Extend applications (data models, business logic, UI pages, orchestration flows) for HR processes not supported natively
• Design and expose Extend REST APIs for internal consumers and external vendor integrations; govern API versioning, OAuth 2.0 authentication, and rate limit strategies
• Lead adoption of Workday Orchestrate for multi-system workflow coordination across Workday and external systems
• Own the Extend and Orchestrate application lifecycle: requirements, design, development, sandbox testing, production deployment, and ongoing maintenance

Production Reliability, Operations & Platform Governance

• Drive operational excellence across the integration portfolio: SLAs, prioritization, and escalation handling
• Own SLAs for the most critical integrations; establish monitoring, alerting, retry logic, idempotency, and runbook standards that raise the bar across the team
• Drive root cause analysis on integration failures and implement preventative controls
• Implement PII handling, audit controls, and data reconciliation strategies meeting GDPR, India PDPB, and SOC 2 requirements
• Enforce data security protocols: PGP, SSH, SFTP, HTTPS, OAuth 2.0, SAML, and WS-Security across all integration surfaces
• Own tenant deployment strategy: sandbox to production promotion, Git-based version control of integration artifacts, and rollback planning

HR Technology & Functional Knowledge

• Maintain a strong working understanding of core HR and payroll processes (hire-to-retire, compensation cycles, benefits enrollment, compliance reporting) sufficient to design integrations that reflect real business requirements
• Partner with Employee Experience, Recruiting, Payroll, Total Rewards, and Legal/Privacy to translate HR process requirements into sound technical architectures
• Understand how HR data flows across the enterprise: from Workday as the system of record through downstream payroll processors, benefits carriers, identity providers, and compliance platforms
• Proactively surface configuration and upstream data issues that affect integration reliability, and partner with functional owners to resolve them
• Bring an employee-centric lens to integration design so the technology we build translates to seamless experiences for the people it serves

Technical Leadership & Cross-Functional Influence

• Act as a technical authority for Workday integrations across BizTech; influence architectural decisions in adjacent teams including middleware, Identity, and Data Platform
• Mentor and upskill senior and mid-level engineers through design reviews, code reviews, pair development, and documented standards
• Translate ambiguous, high-level business requirements into sound technical architectures; clearly communicate constraints, trade-offs, and risks to stakeholders at all levels
• Write authoritative Integration Design Documents and operational runbooks maintainable by the broader team
• Proactively identify systemic risks and integration portfolio health issues; drive resolution and communicate transparently with leadership
• Represent Talent Systems in enterprise architecture forums and vendor technical discussions on integration topics

Required Qualifications

• Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field (or equivalent experience)
• 12+ years of industry experience in software development or systems integration
• 8+ years of hands-on Workday integration development covering the full lifecycle: requirements, design, build, testing, go-live, and post-production support
• Workday Studio: complex integration development experience
• Workday Integration Proficiency (personally written code required)
