Job description

Senior Software Engineer – PowerBuilder

PowerBuilder to .NET migration · 5–8 years experience · Bachelor’s in Computer Science, Software Engineering, or equivalent practical experience

Core Key Responsibilities

Analyze the existing PowerBuilder application — modules, DataWindows, business logic, database interactions, integrations, and dependencies — to establish current behavior.
Support migration of PowerBuilder functionality to .NET / C#, translating existing functionality and business rules into maintainable technical solutions.
Contribute hands-on to the design, development, enhancement, and testing of the replacement .NET implementation.
Identify migration complexity, technical dependencies, gaps, and risks in the legacy codebase, and communicate findings clearly to the project team.
Analyze SQL Server queries, stored procedures, and data dependencies used by the PowerBuilder application and support their transition or reuse in the target solution.
Troubleshoot complex issues across the legacy PowerBuilder modules, the new .NET implementation, databases, integrations, and third-party components.
Document existing PowerBuilder functionality and technical behavior to support migration, testing, traceability, and knowledge transfer.
Develop and maintain unit tests and work with QA to compare legacy and migrated behavior and validate functional equivalence.
Participate in technical analysis, backlog refinement, estimation, sprint planning, and peer code reviews; work with minimal supervision and raise risks early.

Core Technology Skills Required

PowerBuilder — strong hands-on development; able to navigate, understand, troubleshoot, and modify an established codebase.
.NET / C# — hands-on experience sufficient to contribute directly to migration and replacement development.
Legacy modernization — experience migrating or re-platforming legacy applications to .NET or another modern stack, strongly preferred.
SQL Server — queries, stored procedures, and data dependency analysis.
Object-oriented programming, design principles, and application architecture — strong grounding in maintainable code practices.
Git, Visual Studio, and Azure DevOps — source control and development tooling, preferred.
CI/CD — working knowledge of automated build and deployment pipelines, desirable.
Engineering practices — coding standards, code reviews, source control, build processes, testing, deployment, and maintenance.
Reverse engineering — ability to determine legacy application behavior where documentation is limited.
Agile / Scrum — delivery within cross-functional development teams.
Communication — clear documentation of technical findings, dependencies, and migration risks.
