? We’re Hiring: Senior Software Engineer (Payments)
Are you a software engineer with deep experience building and supporting payment systems that process real money at scale?
We’re looking for a Senior Payments Engineer to join our Engineering team and help build, enhance, and modernize a critical payments platform serving local governments across online portals, IVR, kiosks, POS terminals, cashiering, and recurring autopay.
This is not a generalist software engineering role. We’re looking for someone who understands the payment lifecycle, gateway integrations, tokenization, settlement, reconciliation, and PCI DSS — and who enjoys being deeply hands-on. Approximately 75–85% of the role is hands-on engineering.
