Responsibilities

Own the architecture of the ledger and balance services, including the data model, consistency guarantees, and the interfaces other businesses use to read balances and authorize spend.
Design and build distributed services in Java and Spring Boot that handle high transaction volume with strict correctness, idempotency, and auditability requirements.
Model funds by type and eligibility, so that each portion of a customer's balance is usable only where client, product, customer location, and transaction type allow, and so that a regulator-driven restriction can be applied quickly and safely.
Lead the migration of existing business wallets onto the shared ledger in phases, including dual-running, reconciliation, cutover, and rollback plans that avoid customer-visible downtime.
Architect event-driven integration using java and architectural patterns so that balance changes are published reliably and downstream consumers can depend on ordering and delivery.
Carry responsible gaming protections with the balance, working with the Responsible Gaming and Fraud teams so that limits, self-exclusion, and other customer protections remain enforced as funds are used across businesses.
Work with Finance, Legal, and Compliance on how funds are attributed between businesses, how settlement and chargebacks are handled, and what data may be shared across Fanatics entities.
Build for reconciliation and audit, including complete transaction histories, financial reporting feeds, and tooling that lets Operations and Finance verify balances independently.
Lead technical initiatives that span multiple teams, and run architectural reviews, design sessions, and incident postmortems.
Mentor engineers and raise the standard for security, observability, reliability, and testing across the platform.
Partner with product, frontend, and mobile teams so that balance behavior is clear and consistent in every customer-facing experience.
Be open to occasional travel to Fanatics offices or industry events for planning, collaboration, and team development.
