[Remote] Staff Software Engineer - DevEx

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

Skills

• Solid understanding of cloud security, API Gateways, load balancing, and network isolation, viewing security as a fundamental engineering constraint, not an afterthought
• Experience with tokenization, payment processing, or security products
• BA/BS degree
• A knack for out-of-the-box thinking that thrives in a fast-paced startup environment
• Experience designing mandate, credential-provisioning, authentication, attestation, or cryptogram-based workflows
• Experience applying AI developer tools or agentic automation to day-to-day engineering workflows
