About the Role

We are seeking a highly skilled and experienced Senior Mobile Engineer with strong experience in React Native to help scale and evolve Arena Club’s mobile app. As a key member of the team, you’ll deliver new features, refine performance, and ensure world-class user experiences for our growing community of collectors.

  • Partner with backend and web engineers to ensure seamless functionality across platforms
  • Design and implement robust app architectures and complex user interfaces

  • Raise the engineering bar, set development standards, and identify and correct bottlenecks
  • Help maintain code quality, organization, and automation

Qualifications

  • Bachelor’s degree in Computer Science, Engineering, or a related field
  • 7+ years of experience in mobile application development
  • Proficient in React Native with a strong understanding of the iOS and Android ecosystems
  • Familiarity with modern mobile frameworks and tools (Rx, IoC/DI, analytics, A/B testing, Bazel)
  • Experience leading mobile app development projects and deploying apps from scratch
  • Experience with automated testing frameworks and continuous integration
  • Solid understanding of mobile app architecture and life cycle
  • Experience with automated testing frameworks and continuous integration
  • Familiarity with cloud messaging APIs, push notifications, and building e-commerce marketplaces
  • Hands-on experience using AI tools (Claude or Cursor preferred; other agentic tools welcome) to ship code, build agents, and automate workflows
  • Ability to work effectively in a remote team environment and collaborate with engineers across various time zones
  • Strong problem-solving skills and a can-do attitude

The Arena Club Standard

Life at Arena Club isn’t for the faint of heart — and that’s by design. We’re building products and experiences the collectibles world has never seen. This is a proving ground. It demands your best every single day, because anything less means you’re falling behind.

From day one, you’re in the game. Trusted to deliver, expected to own outcomes, and driven to raise the bar higher than you thought possible. We don’t just execute — we innovate, compete, and win together. That’s how real breakthroughs happen.

If you want routine or predictability, you won’t find it here. But if you’re ambitious, relentless, and hungry to prove yourself on a team built to dominate — step into the arena. You’ll discover growth and reward here, unlike anywhere else.
