Note: The job is a remote job and is open to candidates in USA. VGS is hiring a Staff Software Engineer to build secure, reliable payment infrastructure for AI agents through its Agentic API. The role leads API and platform architecture, security, observability, provisioning, testing, and cross-functional delivery for production-critical payment workflows.
Responsibilities
- Architect Agentic Payment Infrastructure: Lead the design and evolution of Python 3.13+ and FastAPI services powering secure, production-critical agentic payment flows
- Define the Core API Platform: Design APIs and domain models for card enrollment, agentic token provisioning, purchase intents, mandates, device attestation, OTP flows, confirmations, and cryptogram retrieval
- Own Security, Reliability & Scale: Drive architectural decisions across security, scalability, availability, performance, and developer experience for sensitive payment and cryptographic workflows
- Build Deep Observability: Establish consistent patterns for error handling, traceability, structured logging, metrics, and distributed tracing using OpenTelemetry and Prometheus
- Automate Platform Provisioning: Design extensible provisioning workflows using Kubernetes APIs and Custom Resource Definitions
- Set the Quality Bar: Define rigorous unit, integration, acceptance, and end-to-end testing strategies for high-risk payment flows, including canary-safe production validation
- Lead Complex Initiatives: Lead technical design reviews, surface architectural and delivery risks early, and drive cross-functional initiatives from initial exploration through reliable production operation
- Pioneer AI-Native Engineering: Apply AI-assisted development and agentic workflows across the SDLC to accelerate prototyping, testing, refactoring, investigation, and delivery while maintaining a high quality and security bar
- Partner Across the Ecosystem: Collaborate with Product, Security, Infrastructure, Platform, and external card-network partners to translate evolving requirements into secure, scalable systems
