🌍 About Hopae

At Hopae, we're building the world's most trusted digital identity platform — private, secure, and built for real life. We believe identity should be in your control — not locked behind outdated systems or centralized gatekeepers.

Our product, Hopae Connect, lets businesses verify real people across borders through a single API — no need to build country-by-country integrations themselves. Our technology powers instant, privacy-first verification across fintech, credentials, supply chain, and gaming — for IDV providers, e-signature platforms, and enterprises who need identity to just work, everywhere.

Backed by top global investors, Hopae operates across Seoul, Paris, Luxembourg, and San Francisco, bringing together exceptional talent from over 10 nationalities. We move fast, think globally, and build products that define the future of identity.

💡 Why You’ll Love It Here
  • Global DNA: Work with exceptional peers across Seoul, Paris, and San Francisco

  • High Impact: Build technology shaping the global trust and identity landscape

  • Ownership Culture: No micromanagement — full trust, full accountability

  • Elite Standards: Work fast, learn fast, and grow with world-class peers

  • Inclusive & Respectful: 10+ nationalities, diverse perspectives, one vision

  • Growth Mindset: Access mentorship, leadership visibility, and continuous learning

🎯 What You'll Do

As a React Native Product Engineer on hConnect, you don't just build features — you own the mobile product experience end-to-end. From problem definition to deployment, you're the person who makes sure our mobile product solves real user problems and runs reliably at global scale.

  • Design and develop mobile products using React Native and TypeScript across diverse countries, user environments, and authentication flows

  • Own the full product lifecycle — problem definition, requirements, implementation, deployment, operations, and iteration

  • Shape the mobile experience for global identity verification — secure, trustworthy, and built for real users

  • Move fast: understand the problem, identify what matters now, build, ship, and improve

  • Collaborate closely with designers and the Product team to raise the bar on direction and quality

  • Leverage AI tools actively as a core part of your development workflow — not as an afterthought

  • Go beyond your immediate scope when the product needs it — you solve what needs solving

🧠 Who You Are

You care more about solving the right problem than perfecting the wrong one. You don't wait for complete specs — you define the scope, make the call, and ship.

  • Hands-on experience building real mobile apps with React Native and TypeScript

  • Product Engineer mindset — you push for better solutions, not just cleaner implementations

  • High autonomy, high accountability — no micromanagement needed

  • Comfortable making decisions in ambiguity — no perfect plan? You find the path anyway

  • Active AI user — you treat tools like Claude Code or Codex as productivity multipliers

Nice to have:

  • 0→1 product experience — built something from idea to launch

  • App Store / Play Store operations — submissions, OTA updates, crash handling

  • Backend or full-stack experience

  • B2B, SaaS, or identity/auth domain experience

⚡️ Fast Facts
  • 💰 $6.5M+ raised from top global investors

  • 📦 2.6M+ downloads of our sd-jwt-js library

  • 🌍 10+ nationalities across 3 hubs

  • 🔬 82 eID research projects completed
