Job description

JOB SUMMARY: The Delphi Software Engineer is responsible for maintaining and modernizing the legacy Delphi application portfolio while leading migration to the new target environment: Azure cloud-native solutions built on C# (Function Apps, App Services, Storage Accounts, Managed Identity, Key Vault, and related services). This role keeps purpose-built applications supporting health plan business capabilities running reliably while still re-platforming for future utilization. KEY RESPONSIBILITIES: Maintain, support, and troubleshoot the existing Delphi application portfolio, including both desktop and web-based solutions, against Oracle and SQL Server databases. Lead modernization of Delphi applications to Azure cloud-native solutions built on C#, including redesign and redevelopment using Function Apps, App Services, Storage Accounts, Managed Identity, and Key Vault. Assess each legacy Delphi application's business logic, data dependencies, and integrations to design an appropriate cloud-native replacement architecture. Develop migration plans that sequence and prioritize which Delphi applications to modernize first, balancing business risk, technical complexity, and ongoing support burden. Write clean, maintainable C# code and apply Azure security and identity best practices (Managed Identity, Key Vault-based secrets management) in all newly built services. Validate data integrity and business logic parity between legacy Delphi applications and their modernized Azure replacements. Partner with Architecture, Data Engineering, and Security teams to align modernization work with target-state cloud architecture and HIPAA/HITRUST-aligned controls. Document legacy application behavior, data flows, and business rules discovered during modernization to preserve institutional knowledge as Delphi systems are retired. Support and troubleshoot Oracle and SQL Server dependencies shared between legacy Delphi applications and their modernized replacements during transition periods. Performs other job-related duties as required or assigned. QUALIFICATIONS: Demonstrated experience maintaining and developing in Delphi (desktop and/or web-based applications). Strong C# development experience, including building and deploying Azure-native services (Function Apps, App Services). Working knowledge of Azure cloud services relevant to application modernization, including Storage Accounts, Managed Identity, and Key Vault. Experience working with both Oracle and SQL Server databases. Proven ability to reverse-engineer and document legacy application logic and data flows in order to replicate them in a modern architecture. Strong problem-solving skills and the judgment to balance legacy system stability against the pace of modernization work. Effective communication skills, with the ability to document technical findings and migration plans for other engineers and IT leadership. Successful completion of Health Care Sanctions background check. EDUCATION/EXPERIENCE: Bachelor's degree in Computer Science, Information Systems, or related field (or equivalent experience). A minimum of three years of experience developing or maintaining Delphi applications. A minimum of two years of experience building applications or services in C# on Azure preferred. Experience modernizing or re-platforming legacy applications to a cloud-native architecture strongly preferred. Experience in healthcare, health plan, or other regulated, data-sensitive environments preferred. Familiarity with Oracle and SQL Server database development and administration preferred.
