About Fanatics Markets
Fanatics Markets is the real-money prediction and trading app where you can invest in moments you care about. Built on a secure platform, we let users predict real-world outcomes and trade on events they actually follow - from sports and entertainment to political elections and beyond. Our mission is to redefine how fans engage with the moments and markets that matter most. We're looking for the right people to help us build the future of prediction markets.
Overview
At Fanatics Betting & Gaming (FBG), a core division of Fanatics' mission to establish the ultimate end-to-end digital platform, we're crafting a world where every aspect of a sports fan's passion is catered to.
On the engineering side, we're pioneering the use of AI as a code collaborator. We need engineers who have gone beyond experimentation: engineers passionate about min/maxing their workflows who actively experiment with Claude Code, Cursor, GitHub Copilot, or similar tools to ship production code faster while maintaining exceptional quality standards. If you have strong opinions about AI-augmented development workflows backed by real experience, we want to talk with you.
This SE III Client Multiplatform Engineer role entrusts you with significant ownership over the development and optimization of both the Kotlin Multiplatform & Compose Multiplatform UX. You'll lead by example, establishing best practices for AI-assisted development while building systems that handle millions of events daily.

Contribute to the development, testing, documentation, and deployment of high-quality, scalable software into production
Develop a comprehensive understanding of the industry, product, and roadmap, leveraging this knowledge to contribute to team strategy and provide input on the direction of the organization
Execute the end-to-end technical implementation of complex features and systems, from ideation and architecture to deployment and refinement across backend & frontend.
Partner closely with product, design, and other stakeholders to make impactful technical decisions that align with both business goals and long-term scalability

Actively participate in team planning and design discussions, contributing innovative approaches to solve technical challenges and optimize design patterns
Drive improvements to software quality, testability, operational metrics, and team documentation, raising the standard within the team
Leverage AI tools to accelerate development velocity while maintaining code quality standards
Follow and contribute to team standards for AI tool usage (prompt patterns, code review checklists, validation strategies)
Track and share insights on AI tool effectiveness through concrete metrics (PR velocity, bug rates, test coverage)
Identify and prevent common AI-generated code pitfalls (over-abstraction, missing edge cases, security vulnerabilities)
Qualifications
3-5 years building highly scalable Android apps

Team-first mentality, with a willingness to do what it takes to get the job done and a desire to strive for better
Demonstrated experience using AI tools (Claude Code, Cursor, Copilot, etc.) to ship production code
Can demonstrate specific examples of workflow improvements (e.g., "reduced boilerplate generation time by 40%")
Has developed personal strategies for validating AI-generated code and identifying common pitfalls
Effectively communicates complex technical concepts clearly to diverse audiences, including engineers and stakeholders
Solid understanding of Agile software delivery and SCRUM methodology, with a track record of contributing to process improvements within teams
Thrives in a high-growth environment where priorities evolve regularly and decisions are made quickly
