About The Position

The Senior Cryptographic Security Engineer is a hands on technical leader
responsible for designing, operating, and evolving the organization’s
cryptographic platforms with a strong emphasis on operational resilience,
automation, and risk reduction.

This role sits at the intersection of cryptography, PKI, certificate lifecycle
management, cloud key management services, automation, and incident prevention.
The Cryptographic Engineering team balances run the platform responsibility with
build the future engineering, ensuring enterprise cryptographic controls are
stable today and adaptable to emerging threats such as post quantum
cryptography.

Requirements

• Eight plus years of experience in cryptographic systems, PKI, or security engineering
• Experience designing, implementing, or supporting large scale enterprise certificate management programs
