About The Position

Global Payments is hiring a Senior Software Engineer for its agentic commerce engineering team. The role will help build secure, reliable backend services for autonomous commerce, enabling AI agents, merchants, payment platforms, and risk systems to work together in real time. The position focuses on infrastructure for trust, identity, user intent, authentication, tokenization, fraud signals, and real-time transaction visibility.

The engineer will develop Java-based backend services and secure checkout and payment APIs, integrate agentic commerce capabilities across payment and merchant systems, and build APIs, SDKs, documentation, sample flows, sandbox experiences, and developer tools. The role owns features from design through deployment and monitoring, and contributes to design and code reviews, service documentation, production readiness, and ongoing platform improvements. This work involves collaboration with product, architecture, security, fraud, checkout, tokenization, gateway, and platform teams.

Requirements

• At least 5 years of software engineering experience, including building and operating production services, APIs, distributed systems, or transaction-processing applications.
• Experience building and operating cloud-based systems on AWS, Google Cloud Platform, or comparable public cloud environments.
• Strong fundamentals in deployment, monitoring, reliability, and secure service design.
• Practical interest in AI agents and agentic workflows, including API calls, structured data, delegated permissions, and validation before real-world actions.
• Strong software engineering fundamentals across API design, testing, CI/CD, observability, secure coding, resilience, maintainability, and production support.
• Ability to collaborate across product, architecture, security, fraud, checkout, tokenization, gateway, and platform teams.

Nice To Haves

• Experience in payments, fintech, commerce, gateways, card-not-present processing, checkout, tokenization, 3DS/SCA, fraud/risk, disputes, merchant reporting, or other high-trust transaction systems.
• Experience building or integrating AI-powered applications, agent frameworks, LLM tool-calling patterns, MCP-style integrations, A2A-style workflows, structured automation systems, or safe AI execution patterns.
• Hands-on experience with Node.js, TypeScript, SDKs, developer tooling, sandbox environments, sample apps, merchant-facing APIs, GitHub projects, open-source tools, standards discussions, AI engineering communities, or technical forums.

Responsibilities

• Design and build secure checkout and payment APIs that AI agents can invoke reliably and deterministically.
• Implement flows to capture and validate agent context, user intent, delegated authority, payment credentials, risk signals, transaction evidence, and downstream reporting data.
• Integrate agentic commerce capabilities with global payment platforms, gateways, checkout, tokenization, authentication, fraud, reporting, and merchant-facing systems.
• Build merchant-facing APIs, SDKs, documentation, sample flows, sandbox experiences, and developer tools.
• Design APIs and developer experiences with clear contracts, predictable errors, strong validation, fast testing, and measurable time-to-first-transaction.
• Use feedback from internal teams, external developers, pilots, and partner integrations to improve the platform.
• Build Java-based backend services for real-time payment workflows, emphasizing performance, observability, security, and operational discipline.
• Own features from design through implementation, testing, deployment, monitoring, and iteration.
• Contribute to design reviews, code reviews, service documentation, production readiness, and high-quality engineering practices.
