Sr. Software Engineer

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.

While we don’t process payments directly, our infrastructure serves as a critical, fault-tolerant security layer that enables our customers to safely process millions of dollars in transactions.

We’re looking for an experienced, product-minded Senior Software Engineer to help build and scale our payments-enabling applications, with a focus on tokenization, credential updating, and card-on-file technologies.

In this role, you’ll design resilient, high-throughput systems capable of handling 1,000+ transactions per second (TPS) with absolute precision.

What you will be doing at VGS…:
•
Product-Minded Collaboration: Partner closely with Product Management to shape the roadmap and define what actually gets built. You won't just be handed technical specs; you will actively collaborate to understand customer pain points and engineer the best possible solutions.

•
Build Mission-Critical Systems: Design, develop, and deploy fault-tolerant, highly available distributed systems capable of handling 1,000+ TPS and securing millions of dollars in sensitive financial data with zero data loss.

•
Cross-Functional Partnership: Work seamlessly across organizational boundaries, partnering deeply with Product, Revenue Ops, Cloud Platform, and Security teams to ensure our payments infrastructure aligns with holistic business and operational requirements.

•
Optimize for Scale and Latency: Tackle complex performance bottlenecks and architect scalable solutions that maintain strict low-latency requirements for high-volume payment flows.

•
Drive Technical Decisions: Engage in technical trade-off discussions, drawing from past industry experience to help the team make informed architecture and design choices for high-throughput environments.

•
Code Quality & Review: Act as a valuable and rigorous code reviewer. Maintain a culture of code quality through comprehensive testing, automation, and adherence to rigorous engineering standards.

•
Full Lifecycle Ownership: Engage proactively in all phases of the software lifecycle, monitoring, alerting, and maintaining your work post-deployment to ensure absolute reliability in production.

What we are looking for from you (Requirements)...:
•
5+ years of experience in software design and development within a Cloud SaaS environment, particularly working on high-throughput, mission-critical distributed systems.

•
Deep experience with payments technologies and the broader ecosystem—specifically tokenization, credential updating, card-on-file architectures, and PSP-adjacent technologies.

•
Solid understanding of cloud-native architecture, microservices, CI/CD (GitHub Actions, Argo), GitOps, Authentication and Authorization, APIs, and API Gateways.

•
Proficiency in Java and Spring Framework/Spring Boot.

•
Hands-on experience with modern cloud infrastructure and streaming technologies: Docker, Kubernetes (EKS), Kafka (MSK), and other AWS services.

•
Experience in building robust backend API specs, mocks, and service implementations.

•
Experience with Observability solutions using Grafana and Open Telemetry to monitor system health at scale.

What you get from us...

• Flexible work hours and flexible PTO

• Competitive health benefits

• VGS stock options

• 401k plan, with employer matching 4% and immediate vesting (available only for US employees)

• Life & disability insurance

• Pre-tax flexible spending accounts, dependent and healthcare FSA (available only for US employees)

At VGS, we have 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—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.

We consider applicants without regard to race, color, national origin, sex, age, religion, sexual orientation, gender identity, veteran status, marital status, physical or mental disability, or other protected classes under all local, state, and federal laws and ordinances (AA/EOE/W/M/Vet/Disabled).

Qualified applicants with arrest and conviction records will be considered for the position in accordance with the San Francisco Fair Chance Ordinance.
