Hard Rock Digital is a team focused on becoming the best online sportsbook, casino, and social gaming company in the world. We’re building a team that resonates passion for learning, operating and building new products and technologies for millions of consumers. We care about each customer's interaction, experience, behavior, and insight and strive to ensure we’re always acting authentically. Rooted in the kindred spirits of Hard Rock and the Seminole Tribe of Florida, the new Hard Rock Digital taps a brand known the world over as the leader in gaming, entertainment, and hospitality.

This is an exciting opportunity to join our rapidly growing technology team, responsible for continuous growth and support of an unrivalled betting experience for millions of sports fans everywhere. We’re looking for a Principal Mobile Engineer who will bring their creativity and experience to Hard Rock Bet to help us build software with a spark of magic. This is a role that works closely with Product Management, Design, QA, and Backend Engineering to deliver a full-featured mobile app.

Your responsibilities will include:

  • Lead the Frontend technical direction of the Casino Technology unit, owning architectural decisions within the domain while ensuring alignment with the broader mobile platform.
  • Partner with peer Principal Engineers in Core and Sportsbook units and the Technical Director for Mobile to define, evolve, and uphold shared engineering standards, patterns, and conventions.
  • Own the architecture and evolution of Casino-domain features within a high-performance React Native application for iOS and Android, serving tens of thousands of daily users across multiple product variants and regulatory jurisdictions.
  • Deep expertise in React Native application architecture using TypeScript in strict mode, with a track record of defining patterns and conventions adopted across engineering teams.
  • Mastery of dual state management strategies — client state (MobX) and server state (TanStack React Query) — including the judgment to enforce clear boundaries between them at scale.
  • Comfortable working with AI-assisted development tools (e.g., Claude Code, Cursor, Codex) and interested in shaping how the team leverages them.
  • Proven experience designing real-time mobile systems using RESTful services, WebSockets, and GraphQL, with an emphasis on resilience, latency, and graceful degradation.
  • Significant native iOS (Swift/Objective-C) and/or Android (Kotlin/Java) experience, particularly in authoring and maintaining native module bridges and managing cross-boundary data flow.
  • Prior experience in the igaming, sportsbook, or online gaming industry, with a strong understanding of the regulatory, compliance, and geolocation constraints that shape product and architecture decisions.
  • Experience architecting multi-variant mobile applications — managing divergent product configurations, jurisdiction-specific logic, and feature flag–driven rollouts within a single codebase.
  • Ownership of cross-cutting technical initiatives such as design system creation, legacy codebase migration strategies, developer tooling, or CI/CD pipeline optimization for App Store and Play Store delivery.
  • Comprehensive knowledge of the mobile development lifecycle — application architecture, OS-level APIs, debugging, performance profiling, security hardening, and deployment.
  • Demonstrated ability to identify, scope, and drive multi-quarter architectural improvements — balancing long-term technical vision against near-term product delivery.
  • A track record of mentoring senior and staff engineers, elevating team capabilities through code review culture, technical documentation, and architectural guidance.
  • Strong cross-functional influence — able to partner with Product, Design, QA, and Backend Engineering leadership to shape roadmaps and make build-vs-buy-vs-migrate decisions.
  • Contagious and positive work ethic that raises the bar for engineering quality across the organization.

We offer our employees more than just competitive compensation. Our team benefits include:

  • Competitive pay and benefits
  • Flexible vacation allowance
  • Flexible work from home or office hours
  • Startup culture backed by a secure, global brand
  • Opportunity to build products enjoyed by millions as part of a passionate team

We care deeply about every interaction our customers have with us, and trust and empower our staff to own and drive their experience. Our vision for our business and customers is built on fostering a diverse and inclusive work environment where regardless of background or beliefs you feel able to be authentic and bring all your talent into play. We want to celebrate you being you (we are an equal opportunities employer).
