📋 Description

• Build and scale core parts of the mobile and web apps in React Native; entry building, review, placement, and tracking. The whole lifecycle. • Investigate and resolve critical issues in the React Native client, and put guardrails in place so they don't recur. • Lead design reviews for initiatives that cut across iOS, Android React Native clients, calling out trade-offs, risks, and failure modes before they become incidents. • Partner with backend, product, and design on entry placement, entry confirmation, slip changes and errors, and bet history to keep the experience fast and consistent • Turn ambiguous, cross-team goals into concrete plans with milestones and clear owners • Use data like product analytics, error dashboards, and session data to validate that fixes actually land and to catch regressions early • Coach other engineers on design reasoning and ownership, and create reusable patterns that other teams adopt • Anticipate and mitigate risks in shared systems before they impact other teams or customers

🎯 Requirements

• 7+ years of professional software engineering experience, with meaningful time spent in React Native and a solid grasp of the native iOS/Android layers underneath it • A track record of solving cross-cutting or ambiguous problems that span multiple services, teams, or platforms; not just staying in your lane • Experience leading technical initiatives (performance work, reliability improvements, developer velocity) with measurable before/after impact • Comfort turning unclear, high-level goals into an executable plan with milestones and owners that other teams actually align on • A collaborative, coaching mindset; you make other engineers better through review and design discussion, not just your own output • Strong written and verbal communication; you can make a technical trade-off legible to product, design, and other engineering teams • Experience with mobile app performance, testability, and shipping reliable features at scale

🏖️ Benefits

• Unlimited PTO (we're extremely flexible with the exception of the first few weeks before & into the NFL season) • 16 weeks of fully paid parental leave • Home office stipend • A connected virtual first culture with a highly engaged distributed workforce • 5% 401k match, FSA, company paid health, dental, vision plan options for employees and dependents
