VGS is the world's leader in payment tokenization.  Large banks, aspiring fintechs, and growing merchants embed our universal token vault into their technology stack to manage the complexities of payment data tokenization across processors and networks, open banking, card issuance, omnichannel loyalty, PCI compliance, payment orchestration, and more. We empower our clients and partners by tokenizing sensitive payment data, limiting compliance scope, and consolidating payments to unlock revenue and business opportunities. VGS provides processor-agnostic tokenization solutions via secure universal token vaults, iframes, mobile SDKs, tokenization proxies, APIs, and data orchestration tooling to support payment acceptance, card issuance, PII and bank account tokenization, and other payments value-added services. Some of the use cases we enable include multi-processor Network Tokenization, Account Updater, payment orchestration, secure settlement file processing, 3DS, and Risk provider connectivity. We are looking for a well-versed, passionate Engineer who wants to play a key role in site reliability engineering and cloud operations of our global cloud infrastructure. We’re seeking individuals with creative problem-solving, enthusiasm for new technologies, and a desire to contribute to our product.
