We are looking for a Senior Software Engineer to join our Overall Game Experience (OGX) team and help us continue to build the future of fantasy sports. Job Summary We are seeking an experienced Staff Software Engineer with deep expertise in TypeScript and React Native to join our Overall Game Experience team. In this role, you will design, build, and own critical features within PrizePicks’ React Native mobile application — including developer experience and tooling, deployment pipelines and CI/CD workflows, large-scale refactors, and overall app health and performance. You will tackle high-scope, complex technical problems, define the technical path from product idea to production, and mentor engineers across your team and the organization. This is a role for someone who thrives on crafting exceptional mobile experiences and wants to have a direct impact on a product used by millions. What You’ll Do • 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. What You Have Experience • 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
