We ignite the passions of global sports fans and maximize the presence and reach for our hundreds of sports partners globally by offering products and services across Fanatics Commerce, Fanatics Collectibles, and Fanatics Betting & Gaming, allowing sports fans to Buy, Collect, and Bet. Through the Fanatics platform, sports fans can buy licensed fan gear, jerseys, lifestyle and streetwear products, headwear, and hardgoods; collect physical and digital trading cards, sports memorabilia, and other digital assets; and bet as the company builds its Sportsbook and iGaming platform. Fanatics has an established database of over 100 million global sports fans; a global partner network with approximately 900 sports properties, including major national and international professional sports leagues, players associations, teams, colleges, college conferences and retail partners, 2,500 athletes and celebrities, and 200 exclusive athletes; and over 2,000 retail locations, including its Lids retail stores. Our more than 22,000 employees are committed to relentlessly enhancing the fan experience and delighting sports fans globally.

About the Company

Fanatics Collectibles is the home of sports cards, trading cards, and collectibles for over 100 million fans worldwide. As part of the global Fanatics platform, we’re rebuilding how collectors discover, buy, sell, and experience their hobby with world class technology and product experiences.

As part of Fanatics’ continued global growth, we are establishing a new technology hub in Mexico City focused on operational excellence, platform scalability, trust, and customer experience. This team partners closely with Customer Experience (CX), Trust & Safety, Fraud Prevention, Payments, and Financial Operations organizations to build scalable systems and operational tooling that support millions of users and transactions globally.

The Role

Topps is transforming the trading card from a physical product into a connected collector experience. Through scanning, digital claiming, progression programs, and partner activations, collectors can authenticate, track, unlock, and redeem rewards tied to the cards they own, connecting physical products with their digital collector accounts.

As a Frontend Software Engineer on the Collector Engagement team, you’ll build the technology and collector-facing experiences that bring these programs to life. You’ll partner closely with Product, Design, Backend, and Platform Engineering to develop progression and quest features, redemption and reward mechanics, leaderboards, retail and live-event check-ins, in-venue experiences, and integrations that turn a card scan into an account-level event. With programs launching around card releases and major sports moments, you’ll help create reusable platform capabilities that support each new experience.

Responsibilities

• Design, develop, test and maintain collector-facing application features and shared components for collector engagement programs
• Build scalable, responsive and resilient experiences covering progression, redemption, leaderboard and check-in flows
• Implement designs with full interaction state coverage, including loading, empty, ineligible, partially complete, expired and error states
• Collaborate with backend engineers and product stakeholders to define and implement APIs and client workflows
• Build scan and QR entry points that perform on low-end devices and constrained networks
• Write clean, maintainable and well-tested code following established frontend best practices
• Contribute to architectural discussions, technical planning and platform improvements
• Contribute to the shared component library so that each new program reuses existing building blocks
• Instrument features for program telemetry so collector actions are consistently measurable
• Optimize application performance, reliability, accessibility and user experience
• Participate in release management, CI/CD improvements and operational support
• Help improve observability, crash reporting and quality standards
• Conduct code reviews and support mentorship across the engineering team
• Stay current with frontend ecosystem trends, libraries and development patterns

Required Qualifications

• 3+ years of professional frontend or mobile development experience
• Strong proficiency in JavaScript and TypeScript and modern component-based development
• Experience with a modern component framework such as React or React Native
• Familiarity with REST or GraphQL APIs, client networking, and asynchronous programming
• Working knowledge of client-side state management, caching, and degraded-network behavior
• Experience building scalable consumer-facing applications
• Ability to implement designs faithfully, including the interaction states not covered in the specification
• Understanding of application performance optimization and testing strategies
• Experience instrumenting analytics and working with the resulting data
• Experience with CI/CD pipelines and version control systems
• Strong collaboration and communication skills within cross-functional environments
• Professional working proficiency in English, with daily collaboration across US-based product and engineering partners
• Bachelor’s degree in Computer Science, Engineering, or related technical field, or equivalent practical experience

Preferred Qualifications

• Experience supporting marketplace, e-commerce, loyalty, or high-engagement consumer applications
• React Native experience, or exposure to native iOS or Android development
• Experience with camera, QR or NFC integration
• Familiarity with GraphQL, WebSockets, or real-time communication technologies
• Experience with analytics, experimentation platforms and observability tooling
• Animation and interaction craft for reward, unlock and reveal moments
• Passion for sports, collectibles, creators, or digital communities

Code-Writing Contribution

This role requires strong hands-on frontend development expertise. Engineers at this level are expected to independently deliver production-ready features, contribute to application architecture and technical design discussions, and maintain high standards for code quality, scalability and user experience consistent with role expectations.
