Design APIs for tokenization, mandates, authentication, attestation, and cryptogram workflows; own security, reliability, observability, testing, Kubernetes provisioning, and production operations. Drive technical initiatives, design reviews, and cross-functional collaboration with product, security, infrastructure, platform, and card-network partners while applying AI-assisted engineering practices.

Drive strategy, discovery, requirements, prioritization, and roadmaps for payment messaging products. Lead complex multinational implementations modernizing banking and acquiring systems. Design configurable, developer-friendly interfaces for interpreting ISO 8583, ISO 20022, and related protocols. Partner with banks, processors, customers, engineering, implementation, executives, and go-to-market teams while integrating with existing platforms and legacy technologies.

Own product strategy and technical integrations for agentic commerce payments. Translate emerging standards into APIs, protocols, trust frameworks, requirements, and roadmaps. Partner with card networks, wallets, AI platforms, and engineering teams to deliver tokenization infrastructure, browser automation tooling, observability, and secure agent-initiated transactions. Represent VGS in standards discussions and shape the company’s technical vision for agent-ready payments.

Leads an autonomous team of 8–10 engineers developing payment acceptance and value-added services such as network tokens, account updater, 3DS, and account validation. Oversees AI-augmented software delivery, architecture, hiring, coaching, roadmap collaboration, reliability, security, incident response, testing, observability, and compliance. Partners cross-functionally to deliver scalable, secure, enterprise-grade financial products and participates in on-call rotations.

Own quality engineering for high-throughput payment systems by architecting automated regression, performance, stress, and load testing. Build emulators for external payment systems, integrate quality gates into CI/CD pipelines, validate microservices, event-driven architectures, and databases, and use Prometheus and Grafana for observability. Apply AI-assisted testing, synthetic data generation, and edge-case analysis while mentoring engineers and preventing incidents through telemetry-driven testing and post-mortems.

Own quality engineering for high-throughput payment systems by designing automated regression suites, performance and load tests, quality gates, external-system emulators, observability-driven test environments, and AI-assisted testing workflows. Partner with feature teams and product leaders to improve reliability, scalability, security, and transactional accuracy. Mentor engineers, support incident prevention, and embed automated validation throughout the software development lifecycle.

Design secure, scalable payment infrastructure solutions for prospective and existing customers. Lead technical discovery, map complex payment flows, create architectures, demos, proposals, proofs of concept, and implementation handoffs. Advise on tokenization, PCI scope reduction, processor connectivity, payment portability, resiliency, and compliance. Partner with Sales, Account Management, Product, Engineering, and customer technical teams, provide launch oversight, influence product strategy, and develop reusable integration assets and reference architectures.

Lead platform engineering for high-scale, multi-region AWS payment infrastructure. Architect immutable, highly available, self-healing systems; automate infrastructure through Terraform, GitOps, CI/CD, and Kubernetes; establish observability with Prometheus, Grafana, and OpenTelemetry; own incident management and resiliency improvements; design private connectivity; and mentor engineers while driving organization-wide platform standards.

Lead the architecture, scaling, reliability, and security of multi-region AWS infrastructure supporting high-throughput payment systems. Build immutable, self-healing environments with Terraform, Kubernetes, GitOps, CI/CD, and automated resiliency. Develop observability using Prometheus, Grafana, and OpenTelemetry; manage incidents and post-mortems; improve engineering velocity through Golden Paths and platform enablement; and mentor engineering teams on reliable infrastructure practices.

Provide hands-on technical support for payment tokenization integrations by debugging network, API, infrastructure, and downstream gateway issues. Own customer onboarding, escalations, incident and maintenance communications, status page updates, and cross-team coordination. Lead customer integrations from kickoff through go-live, create documentation and training, meet SLAs, and serve as the primary Support decision-maker during PT business hours. Participate in an every-third-weekend on-call rotation.
