At Qualia, we've built the leading B2B real estate technology that transforms the home buying and selling experience into a simple, secure, and enjoyable process. Our SMB and Enterprise products bring together users from across the real estate ecosystem—homebuyers and sellers, lenders, title and escrow agents, and real estate agents—onto a single shared digital closing platform, providing greater clarity and transparency to real estate transactions. Today, through our business customers across the country, millions of consumers use Qualia to close on homes every year. WHAT YOU'LL WORK ON Within Qualia, you'll join the Payments team. Every real estate closing ends with money changing hands: earnest money deposits, loan funding, mortgage payoffs, seller proceeds, and commissions. Qualia powers a substantial portion of U.S. residential home sales every year, totaling billions of dollars in transaction volume. The Payments team builds the systems that move those funds safely, accurately, and on time. The stakes are high. A single closing often moves hundreds of thousands of dollars between multiple parties on a tight deadline, and real estate wires are a prime target for fraud. Our mission is to make money movement the most trustworthy part of the closing, so title and escrow teams, and the homebuyers they serve, never have to wonder where their funds are. HOW WE WORK Our engineers are entrepreneurial, pragmatic builders who move quickly without cutting corners, and who are as comfortable owning a project end to end as they are collaborating with a team. We ship frequently, as often as multiple times a day, and work directly with design, compliance, and customer-facing teams to build payment experiences our customers depend on. RESPONSIBILITIES Design, build, and maintain systems that process ACH and wire transfers at scale (billions of dollars annually), including origination, settlement, reconciliation, and exception handling Build and harden payment-processing pipeli

About The Role We’re looking for a Senior Software Engineer, Infrastructure to own the platform that VSCO product and data teams ship on. You’ll join a small infra team that treats AWS, EKS, and GitOps as the default path for new systems, and you’ll spend real time pairing with other teams so - search, Workspace, and data - land in the right Terraform, Helm, and Flux instead of one-off snowflakes. This is a hands-on senior seat. You will design Terraform modules, cut production traffic to EKS, secure traffic with Cloudflare, look for optimizations in our AWS infrastructure, and leave on-call better than you found them. You like production ownership, you can sequence
