Staff Software Engineer (React Native)

PrizePicks is the fastest-growing sports company in North America, recognized for its innovative platform in Daily Fantasy Sports. We are seeking a Staff Software Engineer with expertise in TypeScript and React Native to design and build critical features for our mobile application, while mentoring engineers and driving technical standards.

Responsibilities:

• Own technical direction: Set and evolve the technical standards, architecture, and best practices for your team’s mobile features, ensuring long-term scalability and maintainability of the app
• Lead the hardest problems: Own the design and delivery of the team’s most complex, highest-scope projects — the ones that require deep technical judgment and cross-system thinking
• Drive team efficiency: Identify and implement improvements to developer tooling, build pipelines, and development workflows that enable the entire team to iterate faster and ship with more confidence
• Establish engineering practices: Define and enforce standards for component architecture, testing, accessibility, performance, and mobile deployment across the team
• Mentor all engineers: Provide mentorship to engineers at every level on the team, shaping technical growth, raising the quality bar, and fostering a culture of continuous improvement
• Collaborate at the organizational level: Work with Engineering Managers, Product leadership, and other Staff/Principal engineers to align technical strategy with business objectives
• Own cross-stack integration: Ensure the mobile app integrates effectively with backend services (Go and Rails), driving consistency in API contracts and data flows across the platform
• Participate in on-call rotation: Own systemic reliability improvements and lead incident response for the most critical production issues

Requirements:

• 8–10 years of professional software engineering experience, with deep expertise building production React Native applications at scale
• Proven track record of owning multiple complex technical initiatives and driving them to successful outcomes across a team
• Experience with the full mobile development lifecycle at scale — architecture, build systems, deployment pipelines, and post-release monitoring
• Experience building mobile applications backed by large-scale, high-throughput distributed systems serving millions of users
• History of elevating engineering teams through mentorship, standards-setting, and technical leadership
• Mastery-level TypeScript proficiency — you are a reference point for TypeScript best practices, patterns, and type system usage
• Deep React Native expertise — you have solved hard problems around performance, native modules, complex animations, and cross-platform consistency
• Expert experience with Expo and its ecosystem, monorepo tooling (Yarn workspaces), and mobile build/release infrastructure
• Strong understanding of mobile testing strategies at scale — Jest, Maestro for E2E testing, and quality automation
• Proficiency with CI/CD for mobile and Expo/EAS workflows — automated builds, OTA updates, staged rollouts, app store pipelines
• Understanding of backend API patterns — you can read, reason about, and influence API design across Go and Rails services
• Operates with full autonomy — you define your own work and the work of the team based on what matters most
• Exceptional communicator who can represent technical strategy to engineering leadership and non-technical stakeholders
• Experienced in fully remote engineering organizations
• Comfortable making high-stakes technical decisions with incomplete information
• Experience leveraging AI-assisted development tools across the full development lifecycle — coding, planning, scoping, and code review
• Vision for how AI tooling and agentic coding practices can accelerate team productivity and improve engineering outcomes
