We are looking for a Senior Software Engineer to join our Sportsbook Core Apps engineering team. You will be working on foundational engineering, focusing on improving the underlying frameworks, tooling, and performance that enable FanDuel to deliver an exciting and innovative customer experience.
Working with our React Native Sportsbook application, you will enhance the core React Native platform and shared codebase to improve performance, scalability, reliability, and developer experience. You will collaborate closely with engineers across the organisation to ensure the React Native stack integrates cleanly with native layers and enables feature teams to deliver safely and quickly.
We are looking for skilled engineers who are empathetic communicators with a commitment to continuous improvement and engineering excellence. The ideal candidate has significant experience delivering production React Native applications, can propose pragmatic solutions to performance and platform challenges, and enjoys mentoring others and raising quality standards.
As a member of this team, you will strengthen the foundations of our mobile platform, enabling FanDuel engineers to deliver features more effectively while maintaining platform quality and best practices.
Some of your responsibilities will include:
- Enhancing the core React Native codebase for the Sportsbook app, focusing on performance, scalability, and maintainability
- Profiling and optimising app startup and runtime performance across the React Native stack (rendering, bundle size, memory, JS/native thread work, etc.)
- Building and maintaining shared frameworks, tooling, libraries, and components that support feature teams
- Improving developer experience through better tooling, documentation, templates, CI reliability, and build performance
- Contributing to technical design discussions and leading multi-phase improvements, breaking work into incremental, testable deliveries aligned with team priorities
- Supporting continuous improvement initiatives that raise quality, reduce toil, and improve operational readiness within the domain
- Joining our on-call rota, sharing out-of-hours support duties as part of our incident response process
What We Are Looking For:
- Significant experience delivering production React Native applications (or strong React skills with interest in mobile development)
- Strong TypeScript skills and a solid understanding of React patterns, architecture, and maintainable code practices at scale
- Practical experience profiling and improving performance in React Native applications (startup time, rendering, responsiveness, memory, etc.)
- Experience with React Native native modules/bridging; native Android (Kotlin/Java) and/or iOS (Swift) experience is a plus
- Familiarity with mobile development best practices, testing strategies, and CI/CD pipelines
- Experience working in Agile teams and contributing to collaborative technical standards
- A quality-focused mindset with strong problem-solving skills and the ability to evaluate trade-offs in ambiguous situations
Additionally, our Senior Engineers can:
- Contribute meaningfully to technical design discussions and propose pragmatic solutions aligned with our technical vision
- Take ownership of delivering platform improvements end to end, including measurement, rollout, and iteration
- Mentor and support other engineers, raising the bar through thoughtful reviews, coaching, and knowledge-sharing
- Participate in wider engineering community initiatives and help spread best practices
