About the role

Cleverbase | https://cleverbase.com/ | The Hague, Netherlands | ONSITE (hybrid) | Full-time Cleverbase runs an API platform for online trust: qualified e-signatures, PKI, digital identity and high-assurance identity onboarding for European organisations. We’re now building towards the EU Digital Identity Wallet and the European Business Wallet. Helping customers design and ship their solutions on our platform matters as much to us as building the platform itself. As a Qualified Trust Service Provider under eIDAS, what we ship has to be demonstrably correct, auditable and secure, and we still deploy frequently. We go beyond compliance by applying modern cryptography to better protect personal data, because our mission is everyone secure online. Stack: JVM (Scala with Cats/Cats-Effect, http4s, fs2, doobie), gRPC, Postgres and HSMs for the trust services; TypeScript (React, NestJS, oRPC, Drizzle, Playwright) for web; standards like JSON/XML/PDF signatures and OpenID. Experience with this exact stack isn't required, but interest in cryptography or digital identity is.
