Remote | Full-time

Compensation: $160K - $240K

Our client operates a core banking platform designed specifically for digital assets, enabling fintechs and systemically important financial institutions to build, operate, and scale onchain infrastructure. The platform secures over €100B in assets and powers critical operations—including key management, transaction processing, treasury, and compliance—for over 400 global institutions.

Our client is seeking a Principal Security Engineer to lead product security across the entire ecosystem. In this role, security is built directly into the system's architecture rather than applied as a secondary control. The ideal candidate will take ownership of hardening key management, signing workflows, authentication systems, policy enforcement, and multi-chain integrations.

Beyond core product security and vulnerability management, this position plays a pivotal role in shaping the long-term architectural vision of a platform trusted by tier-one financial institutions. As an organization committed to technical excellence, our client also encourages contribution to the broader security community through research, publications, and industry events.
