Senior Software Engineer

About this role

🌍 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 We believe identity should be in your control — not locked behind outdated systems or centralized gatekeepers.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 Hopae connects businesses to government eIDs and identity systems worldwide through a single platform — across fintech, credentials, supply chain, and gaming. As a Senior Software Engineer at Hopae, you own real problems end to end, across the full stack, in a team where the mission moves fast and the scope is broad by design. This is not a role where you pick a lane and stay in it. You'll work across backend, integrations, infrastructure, and tooling — whatever the product needs. If you thrive in environments where ownership is total and the work is never the same twice, this is for you. - Build and scale the core verification platform — API architecture, verification lifecycle, async processing, event delivery, and production reliability - Connect and operate external identity providers — building adapters, normalization layers, health monitoring, and the tooling that makes adding the next provider faster than the last - Build the infrastructure that takes integrated capabilities to proven in production — developer tooling, E2E test infrastructure, reference environments, and go-live systems - Own quality end to end — you write the tests, you monitor production, you fix what breaks - Investigate failures independently, identify root causes, and fix the system rather than the symptom - Lead projects and technical initiatives — define the approach, align the team, and drive execution through to production - Mentor junior engineers — through code reviews, pair programming, and direct feedback that raises the bar for everyone - Participate in the hiring process — interview candidates and help shape the engineering team we're building - Work directly with Product, partners, and customers when solving a problem requires it — you're not behind a ticket queue 🧠 WHO YOU ARE - 5+ years of software engineering experience — you've personally designed, operated, and taken responsibility for meaningful production systems - Strong backend fundamentals — APIs, distributed systems, async processing, and production reliability are second nature; our stack is TypeScript / JavaScript - Full stack in practice — you go where the problem is, whether that's backend, infrastructure, tooling, or frontend when needed - You own quality: testing, observability, and operational readiness are part of how you work, not someone else's job - Proven ability to lead projects and technical decisions — you set direction, make trade-offs, and bring others with you - Natural mentor — you invest in the people around you and make the team better, not just the codebase - High ownership, low ego — you drive ambiguous problems to resolution without waiting to be told exactly what to do - Based in Seoul; comfortable working in a global, multicultural, English-first environment ⚡️ FAST FACTS - 💰 $13.5M+ raised from top global investors - 📦 2.6M+ downloads of our sd-jwt-js library - 🌍 10+ nationalities across 3 hubs - 🔬 82 eID research projects completed - 🌐 3 projects accepted into the OpenWallet Foundation 🎁 BENEFITS & CULTURE - Unlimited PTO - Remote-friendly work model - Real ownership from Day 1 - High-impact, global product - Multicultural, respectful team 🧭 INTERVIEW PROCESS 1.
