AvidXchange processes payments and automates accounts payable workflows for over 8,800 middle-market businesses. That's a high-value transaction pipeline sitting on .NET-based platforms - a surface area that attracts credential stuffing, business email compromise, and invoice fraud as a matter of course. The threat model is straightforward: intercept or manipulate payment flows at scale, and the financial damage compounds fast.
The security team operates in a space where application-layer integrity and identity assurance aren't theoretical concerns - they're the perimeter. With a headcount exceeding 1,600 and a customer base that trusts the platform to move real money, the engineering culture emphasizes ownership and decision-making authority. Security roles here intersect directly with the payment automation stack, meaning you're defending systems where a single misconfiguration has immediate, measurable downstream impact.
Based in Charlotte, NC, AvidXchange has been operating since 2000 - long enough to have inherited legacy code paths alongside modern builds, which creates the kind of layered attack surface that keeps security engineers honest. The company holds Great Place to Work® certification and maintains structured inclusion and continuous-learning programs.
