Topps Jobs (NOW HIRING)

About the Team

Fanatics Collectibles is a new company operating at the intersection of collectibles, culture, and technology. Backed by world-class investors, operators, and sports & entertainment partners, we are building the global leader in next-generation collectibles. As part of the broader Fanatics ecosystem, we leverage a digital sports platform that spans over 900 sports properties and engages more than 81 million fans. Together, we are reimagining every part of the collectibles experience for fans, partners, and creators.

Topps.com is a flagship platform within Fanatics Collectibles. We're building the gold standard for collectors through immersive, commerce-integrated experiences across Topps, Fanatics Live, and Fanatics Collect. Our mission is to deliver performant systems, high-design polish, and data-driven growth experiences that engage the next generation of fans.

We're hiring a Full Stack Software Engineer (TP3) to join the Growth Engineering team, focused on driving user acquisition, engagement, retention, and experimentation across Topps, Fanatics Live, and Fanatics Collect.
This role sits at the intersection of product experimentation, analytics, and platform engineering. The engineer in this role will independently design and deliver scalable full stack solutions, contribute to experimentation infrastructure, and partner cross-functionally to improve growth outcomes across consumer-facing products.
As a TP3 engineer, this individual is expected to operate with increasing autonomy, solve moderately complex technical problems, contribute to architectural discussions, and influence engineering best practices while delivering measurable business impact.
This role reports to the Director of Engineering, Topps.

• Design, build, test, deploy, and maintain full stack features that drive user growth, engagement, and conversion across Topps, Fanatics Live, and Fanatics Collect.
• Develop scalable frontend and backend solutions using modern web technologies and engineering best practices.
• Ensure analytics data integrity and consistency across platforms, including instrumentation, tracking pipelines, attribution, and validation frameworks.
• Design and implement experimentation capabilities such as A/B testing frameworks, feature flags, and growth experimentation tooling.
• Partner cross-functionally with Product, Data Science, Analytics, and Marketing teams to translate growth hypotheses into scalable technical solutions.
• Optimize web and mobile experiences with a focus on performance, usability, reliability, and measurable business outcomes.
• Identify and resolve issues impacting data quality, experimentation accuracy, and reporting reliability.
• Participate in system design discussions and contribute to architectural decisions that improve scalability and engineering velocity.
• Contribute to shared platform capabilities supporting cross-product growth initiatives.
• Participate in code reviews, operational support, technical documentation, and continuous improvement initiatives.
• Mentor junior engineers through collaboration, technical guidance, and engineering best practices.

• 5+ years of professional experience building and scaling modern web applications across frontend and backend systems.
• Strong proficiency in full stack development using technologies such as JavaScript/TypeScript, React, Node.js, or equivalent modern frameworks.
• Experience designing and maintaining analytics tracking systems, event instrumentation, attribution pipelines, and experimentation tooling.
• Experience building scalable APIs, distributed systems, and performant consumer-facing applications.
• Familiarity with A/B testing frameworks, experimentation platforms, and feature flagging systems.
• Strong understanding of system architecture, API design, observability, and performance optimization.
• Experience collaborating cross-functionally with Product, Analytics, Data Science, and Marketing stakeholders.
• Ability to independently drive technical solutions from design through production deployment.
• Strong debugging, problem-solving, and communication skills.
• Bachelor's degree in Computer Science, Engineering, or related technical field, or equivalent practical experience.

• Experience working on Growth Engineering or product growth-focused teams.
• Familiarity with tools such as Segment, Amplitude, Snowflake, or similar analytics and experimentation platforms.
• Experience building for mobile platforms, including React Native, native mobile applications, or mobile web optimization.
• Experience supporting high-traffic consumer-facing platforms with rapid experimentation cycles.
• Interest in collectibles, live commerce, fan engagement, or marketplace platforms.

• Demonstrates ownership and accountability for technical outcomes and operational excellence.
• Comfortable operating in fast-paced, evolving environments with shifting priorities.
• Strong collaboration and communication skills across technical and non-technical teams.
• Passion for building high-quality user experiences and data-informed product solutions.
• Growth mindset with eagerness to continuously learn, adapt, and support team development.
• Ability to balance experimentation velocity with long-term platform scalability and maintainability.

This role requires active hands-on software development across frontend and backend systems. A TP3 engineer is expected to independently write production-quality code, contribute to system and feature design, implement scalable experimentation and analytics capabilities, and deliver moderately complex technical solutions with minimal oversight. Code contributions should demonstrate maintainability, testing discipline, architectural awareness, and increasing ownership aligned with TP3 engineering expectations.
