Back End Developer - Node.js / TypeScript

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 We believe identity should be in your control — not locked behind outdated systems or centralized gatekeepers.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.
