About Us

Fanatics is a leading global sports platform redefining how fans connect with the teams, players and moments they love. Our businesses — Fanatics Commerce, Fanatics Collectibles, Fanatics Betting & Gaming, Fanatics Events, Fanatics Advertising, Fanatics Markets and Fanatics Studios — maximize the presence and reach for hundreds of partners globally and create a one-stop experience that allows fans to buy, bet, collect, and earn, while engaging with sports in deeper, more immersive ways. This includes licensed fan gear and lifestyle products, sportsbook and iGaming, physical and digital trading cards, live events, premium sports entertainment content, credit card offerings and more. Together, they form a powerful, integrated ecosystem — connected by the Fanatics ONE loyalty program and FanCash, the currency of sport — delivering personalized experiences to over 100 million fans worldwide. Fanatics holds partnerships with over 900 sports properties, from professional leagues and players’ associations to teams, colleges and retail partners; over 7,000 athletes and celebrities; and over 2,000 retail locations, including all Lids stores. Backed by a team of more than 22,000 employees, Fanatics is committed to relentlessly enhancing the fan experience.

About the Team

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.

Responsibilities

  • Lead the technical design and delivery of partner onboarding systems, integration platforms, and APIs that connect external partners to Fanatics ONE
  • Architect and build the Account Linking Platform, enabling fans to seamlessly connect external partner accounts to their Fanatics ONE identity
  • Drive identity provider integrations, ensuring partners can connect to Fanatics Identity reliably and securely at scale
  • Build loyalty program integration systems that allow partners to participate in FanCash, Tier Point, and One Credit earning & redemption without requiring bespoke integrations for each partner
  • Own technical quality across the team, establishing patterns, reviewing code, setting standards, and ensuring systems are observable, testable, and maintainable
  • Partner with Identity, Loyalty, and SDK engineering teams within Fanatics Core to align on shared APIs, contracts and integration patterns as well as architecture and development patterns
  • Engage directly with external partners and their technical teams to understand integration requirements and translate them into scalable platform solutions
  • Identify and drive improvements to developer experience, including tooling, documentation, and self-service capabilities that reduce partner integration time
  • Mentor engineers across the team, raising the technical bar through pairing, design reviews, and engineering culture

Required Qualifications

  • 8+ years of software engineering experience, with 2+ years in a staff-level or equivalent technical leadership role
  • Strong full stack engineering background, comfortable across backend services, APIs, and frontend tooling
  • Deep experience designing and building integration platforms, partner APIs, or developer-facing systems
  • Proven experience with OAuth 2.0, OpenID Connect, SAML, and identity provider integrations
  • Track record of architecting distributed systems that operate reliably at scale
  • Strong written and verbal communication skills, with the ability to drive alignment across engineering, product, and external stakeholders
  • Experience working in a multi-tenant or multi-opco environment

Preferred Qualifications

  • Experience working with GO and Typescript/React
  • Experience with loyalty, rewards, or payments platforms
  • Familiarity with event-driven architectures (Kafka or similar)
  • Experience building account linking or federation systems
  • Prior experience at a sportsbook, fintech, or regulated industry

If you possess some of these qualifications but not all of them, we still encourage you to apply!

Depending on the role, your interview and onboarding experience may include in-person components, such as onsite interviews or Launching into Better: LIVE—a multi-day cultural immersion in New York City for full-time, non-seasonal hires. These sessions are designed to build connection and bring our culture to life, though specific travel and participation requirements will be confirmed based on your role and location. Your recruiter will provide clear guidance at each stage of the process.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
