With teams across North America, Europe, Latin America, and Asia, we work with the most ambitious companies in financial services, healthcare, media, and technology — helping them move faster, modernize boldly, and compete on their own terms. Management of a Mission-Critical Platform: 3Pillar invites you to join an elite team taking direct ownership of the legacy code that runs a regulated, multi-state utility-and-rent billing platform. Imagine you: stabilizing 18-year-old VB6 components that touch every resident bill, reverse-documenting modules no one else can read, and partnering with the active core-engine owner to keep month-end running while the strangler-fig modernization unfolds around you. This role is not a greenfield assignment and is not a maintenance-only seat.
It is a high-leverage role for an engineer who is energized by complex, undocumented, regulation-bound code — and who knows how to make a legacy estate safer, more observable, and more migratable, one surface at a time. Seize the chance to be the person the team trusts when the bill-generation cycle,



the rate-aggregation engine, or a state-specific tax proc needs an expert's hand.
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.
A minimum of 6+ years of experience as a software engineer.
