Staff Software Engineer (React Native)

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

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
