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.

- 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.
