Fanaticsfbg Staff Engineer at Fanaticsfbg owns architecture and development of payments platform for deposits, withdrawals, and payments. This role involves building distributed services in Java and Spring Boot to handle high transaction volumes.
Responsibilities
Own the architecture of the payments platform, including provider integrations, deposit and withdrawal flows, and the services other Fanatics businesses call to take payment.
Design and build distributed services in Java and Spring Boot that process high transaction volume with strict requirements for correctness, security, and uptime.
Build payment orchestration and routing across processors, acquirers, and payment methods, using approval rate, cost, and provider health to decide where each transaction goes, with failover when a provider degrades.
Handle failure in third-party integrations by design, including timeouts, retries, idempotency, duplicate callbacks, partial failures, and reconciliation against provider and bank settlement files.
Lead the technical work of onboarding new providers and banking partners, including evaluating options and defining the integration, testing, and rollout approach.
Build in regulatory and card scheme requirements, such as per-jurisdiction rules and how transactions are classified, in partnership with Legal, Compliance, and Finance.
Work with Fraud and Risk to bring risk signals into the payment path and to handle chargebacks and disputes, including how they are attributed when funds are used across businesses.
Reduce payment cost through routing, provider terms, and design choices that avoid unnecessary movement of money.
Set standards for security, data handling, and limiting PCI scope across payment services.
Lead architectural reviews, design sessions, and incident postmortems, and mentor engineers across the team.
Partner with product, frontend, and mobile teams so that payment experiences are consistent and clear for customers.
Be open to occasional travel to Fanatics offices or industry events for planning, collaboration, and team development.
