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.

• Architect and maintain scalable, reliable infrastructure: Design and optimize infrastructure for high availability, fault tolerance, and performance across distributed systems.

• Performance tuning and capacity planning: Identify bottlenecks and optimization opportunities, and implement scaling strategies to handle traffic spikes and growing workloads efficiently.
• Collaborate with cross-functional teams: Work closely with software engineers, product teams, and DevOps to enhance system reliability and delivery pipelines.
• Improve operational processes: Champion continuous improvement initiatives in deployment, scaling, and performance testing, while advocating for the adoption of SRE best practices across the organization.
• Mentorship and leadership: Provide technical mentorship to junior engineers, contribute to strategic decisions around infrastructure, and ensure best practices are implemented at scale.
• Be proactive and innovative: we rely on your feedback to build a world-class product.

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