Application Security Engineer

About VGS

VGS is building the trust infrastructure for a new era of commerce. As commerce becomes agentic, payments are increasing dramatically in volume, speed, and complexity, and the companies driving that shift need a foundation they can fully trust.

That's where VGS comes in. We're the world's leader in payment tokenization, trusted by the most innovative AI and Fortune 500 companies, merchants, banks, and fintechs to power modern payments and agentic commerce. We store more than 9 billion tokens and process more than 10 billion monthly interactions, touching a third of all e-commerce. That scale isn't incidental. It's why leading companies embed our universal token vault and credential management platform directly into their stack, taming the complexity of payment data so they can move faster.

Come build the platform that enables modern payments for the world's largest companies. We're helping businesses unlock new possibilities in an industry that never stops moving. And that takes exceptional people.

How We Work

At VGS, we embrace a remote-first philosophy because we believe flexibility leads to great work and a healthy work-life balance. That said, if you live within 30 miles of one of our office locations, you'll be on a hybrid schedule with some in-person time, because we know there's real value in coming together.

We're not about being in the office every day. We are about connection, collaboration, and the energy that comes from a great brainstorm, a team lunch, or celebrating a big win in person.
