ADP is seeking a Lead Application Developer to drive end-to-end solution delivery across our application portfolio. This role combines hands-on development with technical leadership—guiding design, code quality, data integration, and reporting capabilities across a complex ecosystem that includes .NET, SQL Server, Oracle/Oracle APEX, Salesforce, and ADP data sources.

What You’ll Do
Own solution delivery across the full SDLC: requirements, design, development, testing, deployment, and support. Design and build .NET applications (VB.NET, C#, ASP.NET, .NET Core) with clean architecture and testable patterns. Develop robust data layers using SQL Server (T-SQL queries, views, functions, stored procedures) and Oracle (PL/SQL) and build apps in APEX where appropriate. Create dashboards and reports using SSRS and/or other BI tools; establish data models and govern data refresh and access. Integrate systems via REST APIs (consume and orchestrate), including Salesforce and internal/external services. Leverage ADP data (e.g., Databricks, Oracle, DB2, SQL Server instances) and apply ADP RS SORs understanding for authoritative data sourcing and data lineage. Author high-quality technical documentation (solution designs, data dictionaries, specs, deployment guides). Partner with product owners and business SMEs to clarify requirements, size work, and prioritize backlogs. Champion best practices in security, performance, reliability, and observability.Required Qualifications

Data ecosystem knowledge in ADP: awareness of core data sources such as Databricks, Oracle, DB2, SQL Server instances, and how to design integrations with them. ADP RS SORs understanding and how systems-of-record impact integration, data quality, and reporting. REST API consumption: authentication (OAuth 2.0/Bearer), pagination, error handling, and resilience patterns. Technical writing capabilities: architecture diagrams, sequence flows, ADRs, and runbooks.Preferred Qualifications
Experience with CI/CD (Azure DevOps, GitHub Actions, or similar), automated testing, and infrastructure-as-code basics.
