About the Role

We are looking for a hands-on PowerBuilder expert with proven experience leading legacy application modernization and migration initiatives. This role combines deep technical PowerBuilder expertise with the ability to independently assess legacy systems, define modernization roadmaps, and lead delivery workstreams that take applications from legacy platforms to modern architectures.

Key Responsibilities
- Lead assessment of legacy PowerBuilder applications — object inventory, complexity/effort analysis, target architecture recommendations, and migration roadmaps.
- Own and drive a significant workstream within a larger modernization program, from assessment through delivery.
- Develop, maintain, and re-engineer PowerBuilder applications, including DataWindows, user objects, inheritance structures, events, and functions.
- Guide the decomposition of monolithic PowerBuilder applications into services/modules aligned with target architecture (.NET, Java, or web-based stacks).
- Lead or contribute to cross-database migration efforts (e.g., Sybase to SQL Server or Oracle),



including dialect conversion and data migration.
- Write and optimize complex SQL — queries, stored procedures, indexing, and performance tuning.
- Mentor developers, conduct code reviews, and serve as a technical point of contact for client stakeholders.
- Produce explicit technical documentation to support delivery teams and knowledge transfer.
- Collaborate using Git and standard defect/task tracking tools within an agile delivery environment.

Required Skills and Experience
- Hands-on PowerBuilder development experience, including PowerBuilder 2019 or later (2019 R3, 2021, 2022 R3 or newer), along with experience on older versions (PB 9/10/11/12.x).
- Experience with PowerBuilder framework code (PFC or in-house frameworks).
- Strong PowerScript skills with practical depth in DataWindows, user objects, inheritance, events, and functions.
- Demonstrable experience on at least one PowerB
