Job Description
Senior Visual Basic Software Developer maintaining legacy billing systems for regulated utility and rent billing platforms at 3Pillar. Involves working with VB6 and ASP technologies.
Responsibilities:
- Independently own, maintain, and extend the legacy billing surfaces — the VB6 COM components, the classic ASP / VBScript operator pages, the SQL Server T-SQL billing procedures, and the ASP.NET WebForms screens that wrap them.
- Partner with the existing COM component owner (who keeps the bill-generation core) on shared interfaces, change windows, and parallel-run validation.
- Reverse-document and add safety tests to the highest-risk undocumented modules — the rate-aggregation engine, the jurisdiction-specific tax and regulatory procs (CARE / FERA / WSA / state-specific admin fees), the classic-ASP operator UI for revenue-affecting workflows, and the Australia-specific billing logic and its opaque property-settings keys.
- Prove and maintain the VB6 build for the full legacy estate, including the three licensed-dependency report DLLs (ActiveReports 2.0 components, Persits AspPDF, SoftArtisans ExcelWriter 4.0).
- Plan and execute the migration of the most fragile legacy surfaces over time
Requirements:
- A minimum of 6+ years of experience as a software engineer.
- Strong, current expertise in
- VB6 and COM / COM+ interop,
- classic ASP and VBScript,
- T-SQL on Microsoft SQL Server (stored procedures, query tuning, schema reasoning),
- ASP.NET WebForms.
- High level of English proficiency required to interact with a globally-based engineering and operations team.
- A demonstrable track record of reading, decoding, and documenting undocumented legacy code.
- Experience working alongside an active code owner on a shared critical-path component, including change-window coordination and parallel-run validation.
- Strong instincts for safety-of-change: small commits, change-budget thinking, parallel-run validation, feature-flag gating, and explicit rollback plans.
Benefits:
- Medical Insurance benefits as per company policy.
- Life Insurance as per company policy
- 12 days of paid vacation, sick leave and paid holidays as per local law
- Paternity and maternity leave as per as per local law
- Marriage, bereavement and graduation leaves as per company policy
