Must be located near or within the Raleigh-Durham area.

Toshiba Global Commerce Solutions is seeking a hands-on Senior Engineer IV to lead the transaction-processing core of our payment systems platform. Responsibilities include ownership of the terminal transport layer, store-and-forward (SAF) handling, decline and exception fallback logic, and BIN-based routing to ensure reliable card-present payments across our retail network.

This is a hands-on role, not focused on requirements documentation or committee work. You will work directly with transport and transaction-state code, reproduce terminal-level failures, and manage fixes through to production. Success requires strong expertise in banking and card payments, including issuers, card networks, acquiring processors, authorization and settlement flows, and distributed-systems engineering.

This position offers a clear path to payment architecture ownership. You will apply your distributed-systems and Java expertise, learn our payment transaction lifecycle and terminal protocols through hands-on defect resolution and root-cause analysis in your first year, and advance to architectural ownership of the payment transport and transaction-integrity layer.

Our technology stack includes Java and JavaScript applications built with Maven and delivered through a Jenkins CI/CD pipeline. We use a Vue 3/TypeScript POS checkout client that interacts with our transaction and device APIs. Docker and Kubernetes support our build, test, and deployment processes. We use OpenTelemetry for observability across transaction and transport paths, and follow an AI-first development model in which coding agents operate within defined scopes and must provide test and security evidence before changes are accepted.

Responsibilities

• Take ownership of the TCP transport layer between terminals and the payment platform, including heartbeat and keepalive validation, idle-connection management, and reconnect or timeout handling.
• Manage store-and-forward (SAF) behavior for declined or unreachable authorizations, ensuring fallback activates only for genuine connectivity or timeout issues, and not for legitimate declines that should not be queued or replayed.
• Oversee BIN-based routing and processor or network selection logic, including handling BIN table changes, program updates, and network-specific contactless or EMV requirements.
• Diagnose and resolve terminal-side exceptions and faults that appear as ambiguous errors, identifying root causes in code, protocol, or hardware and firmware interactions, rather than relying on retries.
• Lead root-cause analysis for production payment-processing incidents that impact transaction in
