Sr Workday Applications Engineer

About the role

You are a key contributor to the team, leading the way on the most important integration and application initiatives, designs, and operational events across Workday and the broader enterprise ecosystem. You habitually design effective architectures, deliver critical bodies of code and integration, and shepherd the quality of the team's outputs. You are an expert on your team's systems and business domain, and you understand how they fit into the larger cross-team architecture. You contribute to projects that cut across teams and domains, and you are relied upon to resolve critical operational incidents, meet essential deadlines, and propose effective designs.

Responsibilities

• Serve as the technical lead for complex integration and application work across Workday, Gem, BrightHire, ServiceNow, AD/Okta, payroll and benefits vendors, and internal platforms; define the reusable patterns and set standards for the team
• Build complex integrations, services & applications using Workday Studio, EIB, Core Connectors, and REST/SOAP/GraphQL APIs, and architect Extend applications (custom objects, validations, orchestration-backed workflows)
• Act as an expert in multiple subdomains owned by your team; influence and shape team architecture, working closely with Principal and other senior Engineers, and treat testability, resiliency, and observability as first-order concerns
• Design and own MCP (Model Context Protocol) servers and connectors that expose Workday capabilities to AI agents and internal tooling; treat the AI-enablement layer as first-class platform work
• Establish how the team uses and adopts AI-assisted IDEs and coding agents (Claude Code, Cursor, GitHub Copilot); raise delivery speed and code quality across the team/org, not just your own output
• Set the standard for observability across the integration estate (dashboards, metrics, alerts, and runbooks); resolve complex, high-severity production issues at the root cause and drive measurable improvements in platform health and reliability
• Act as a focal point for projects: coordinating deliverables, writing designs, ensuring accurate estimates, and reviewing artifacts
• Mentor engineers, improving their craft and integrating them into team culture and process
• Communicate consistently with technical and non-technical staff, documenting decisions and the rationale behind build/buy and design tradeoffs
