About The Position

Toast’s People Technology team is building a connected technology ecosystem that helps the company scale and provides intuitive self-service experiences for employees and managers. The Principal HR Integrations Architect serves as a senior technical advisor and hands-on integration leader, defining architecture, standards, and roadmaps for the People technology ecosystem. The role evaluates approaches such as build versus buy, point-to-point integrations, middleware, event-driven patterns, Workday Extend, iPaaS, and AI-enabled tools.

The architect develops, tests, and deploys scalable Workday integrations and owns delivery from discovery and architecture through testing, deployment, hypercare, and ongoing optimization. The position partners with People, Payroll, Benefits, Talent Acquisition, Finance, IT, Security, Enterprise Architecture, and vendors to translate business needs into technical designs and data mappings. It also leads production troubleshooting and systemic improvements, strengthens integration monitoring and governance, protects sensitive employee data, documents standards and systems, and mentors teammates.

Requirements

• 8+ years of integration engineering experience, including 5+ years designing, building, and supporting Workday integrations in a complex enterprise environment.
• Deep, hands-on experience with Workday Studio, EIB, Core Connectors, Cloud Connect, PECI, Workday Web Services, RaaS, calculated fields, and custom reporting.
• Strong working knowledge of REST, SOAP, XML, XSLT, JSON, WSDL, XPath, SFTP, and HTTPS.
• Experience applying OAuth 2.0, SAML, SSL/TLS, and PGP encryption to sensitive data flows.
• Demonstrated ability to make and defend sound architecture trade-offs, including speed versus technical debt, synchronous versus asynchronous designs, and build versus buy, in scalable systems.
• Proven ability to partner with non-technical business leaders, uncover business needs, and explain technical trade-offs in plain language.
• Experience leading cross-functional integration initiatives from ambiguity through delivery, including when requirements, API specifications, or platform access are incomplete.
• Strong analytical and troubleshooting skills, including experience resolving production integration issues and driving permanent fixes through Jira or ServiceNow.
• Solid understanding of core HR functional areas, including HCM, Payroll, Benefits, Compensation, and Time & Attendance, and effective-dated HR data.

Nice To Haves

• Workday Pro Certification in Integrations.
• Experience with Workday Extend or Workday Prism Analytics.
• Hands-on experience with iPaaS or middleware such as Boomi or MuleSoft, or event-driven patterns such as messaging queues, retries, and idempotency design.
• Familiarity with adjacent technology stacks such as Greenhouse, ServiceNow, CloudPay, ADP, Okta, or NetSuite.
• Experience applying AI tooling to integration development, testing, or support.
• Background supporting People Technology in a fast-paced, high-growth, or global matrix environment.

Responsibilities

• Act as a trusted technical advisor to People Technology and business leaders; lead discovery to clarify problems, outcomes, constraints, scope, trade-offs, and timelines.

• Design, develop, test, and deploy scalable Workday integrations using Workday Studio, EIB, Core Connectors, Cloud Connect, PECI, and Web Services; personally handle complex and high-risk builds.
• Partner with People, Payroll, Benefits, Talent Acquisition, Finance, IT, and Security to translate business needs into technical designs and data mappings.
• Own integrations end to end, from discovery and architecture through testing, deployment, hypercare, and ongoing optimization, including Open Enrollment, payroll cycles, and major go-lives.
• Prioritize competing requests using criteria tied to business impact and risk, and influence Enterprise Architecture, Security, and vendors on design decisions.
• Manage the integration service queue, troubleshoot production failures, perform root-cause analysis, and implement systemic fixes that reduce technical debt, manual handoffs, and failure rates.
• Improve monitoring, alerting, logging, error handling, and release testing, including testing for Workday biannual updates.
• Protect sensitive employee data, including PII, compensation, and employee-relations data, through secure-by-design practices.
• Coordinate with integration teammates to define swim lanes, shared standards, and a consistent operating rhythm.
• Create and maintain runbooks, integration specifications, and data flow diagrams; lead design reviews and mentor peers on integration best practices.
