About the Technology team
Our Technology teams build the financial infrastructure that moves money for millions of people across the globe. We work on distributed systems at scale — from the payment kernel to AI-powered fraud detection — and we operate on the belief that great engineering is the foundation of everything CloudWalk does.
About this role
This role sits on a team that owns both auth and ledger, so you'll occasionally pick up work across both areas.
- Develop and maintain authentication systems used by both customers and internal services - Build and operate token issuance, validation, and rotation - Maintain HSM-backed key management and signing infrastructure - Improve the security of auth flows in a regulated financial environment - Build SDKs and tooling that other engineering teams use to integrate with auth - Communicate clearly with both technical and non-technical stakeholders
