Fanatics Inc. · New York, NY, United States ·
Staff-level full stack engineer on Fanatics Core's Partnerships Engineering team, owning the systems that onboard external partners and operating companies into the Fanatics ONE loyalty/identity ecosystem — building account linking, identity provider integrations (OAuth/OIDC/SAML), and partner APIs using Go, TypeScript/React, and event-driven infrastructure like Kafka.
Every time a fan places a bet, earns a reward, or checks out on Fanatics — Fanatics Core made that possible. We build the shared foundations — identity, payments, loyalty, wallet, data, and platform — that power sports betting, ecommerce, collectibles, and beyond. We supercharge the business by providing products and capabilities so that teams can focus on what matters most: building delightful experiences for the fans.
Fanatics is uniquely positioned at the intersection of sports commerce, betting, and collectibles, and Fanatics ONE is the loyalty and identity program that ties it all together. As part of the Loyalty SDK team at Fanatics, we build the technology that powers how fans see and interact with FanCash across the entire company. Our SDKs and services sit at the heart of the customer journey, enabling every brand and product team to deliver consistent and seamless loyalty experiences.
Overview
As a Staff Engineer on our Partnerships Engineering team, a critical part of Fanatics Core, you will own the systems and platforms that bring new operating companies and external partners into the Fanatics ONE ecosystem, spanning identity provider integrations, loyalty program onboarding, account linking, and the infrastructure that makes it fast and reliable to connect partners to our platform.
This is a staff-level role: you will be a technical leader and hands-on builder. You'll drive architecture and design decisions, set engineering standards, and work across the full stack to deliver systems that are reliable, scalable, and built to grow with an expanding partner ecosystem. You'll collaborate closely with product, engineering leads across Identity, Loyalty, and SDK, and directly with external partners to solve complex integration challenges.
