About Legado

Our platform, CommsHub, Digital Vault, and LegadoSign, powers secure, compliant, auditable digital engagement at scale. We sit at the intersection of technology, regulation and customer experience, helping institutions move away from fragmented email, paper and legacy portals towards a modern, secure engagement layer. 

Backed by FNZ and Souter Investments, and trusted by leading financial institutions, we are building the infrastructure for compliant digital communication in regulated markets. 

This is not brochureware SaaS. This is secure messaging, durable medium delivery, evidencing, signing workflows and document control inside complex, high-stakes environments.

You will build scalable, secure systems used by regulated financial institutions, where reliability, auditability and performance genuinely matter.

• Advocating for quality, maintainability and low technical debt 
• Collaborating closely with Product, Design and Engineering peers
