Must-Have

Backend

• Over 10 years in server-side engineering, including 5 to 7 years specializing in Kotlin or Java with Spring Boot development.
• Redis — session management, distributed locking, caching
• PostgreSQL — schema design, migrations
• REST API design and HTTP security headers
• English proficiency (reading, writing, and verbal) — the primary working language across the team and organization for daily communication, code reviews, and technical documentation.

Security & Auth

• Strong Spring Security expertise — filter chains, OAuth2 Resource Server
• Working knowledge of OAuth 2.0 / OIDC — authorization code, client credentials, token exchange, introspection
• Understanding at least one: DPoP (RFC 9449), mTLS (RFC 8705), PKCE, FIDO2/WebAuthn
• Familiarity with JWT structure — claims, JWKS, key rotation
• Strong knowledge of authentication, authorization, session management, and secure web application development.
• Strong understanding of the OWASP Top 10 — common web vulnerabilities, mitigation, and secure coding practices

Infrastructure

• AWS — ECS/Fargate, Secrets Manager, VPC basics
• Terraform or similar IaC
• API integration testing (Karate preferred)

Nice-to-Have

• Experience with Authlete
• FAPI 2.0 Security Profile or financial-grade API standards
• Microsoft Entra ID — SAML/OIDC federation, FIDO2 key enforcement
• Cloudflare/ Akamia — mTLS termination, WAF, client certificate forwarding
• WebAuthn/FIDO2 ceremonies — attestation, assertion, discoverable credentials
• Fintech/banking background — FSA regulations, maker-checker patterns, audit logging
• Japanese language ability (reading/basic communication) — a plus for requirement docs

Why This Role

• 🏦 Real regulated bank — not a fintech startup, not a toy project. FSA-supervised, launching in Japan.
• 🔐 Cutting-edge security standards — FAPI 2.0, DPoP, WebAuthn/FIDO2. Few teams globally work at this intersection.
• 🚀 High ownership — small team, big scope. You'll own entire authentication channels, not just implement tickets.
• 🌏 Global collaboration — work with engineers across Japan, Vietnam, and India on a greenfield digital banking platform.
