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.
