About the Role
Solidgate builds financial infrastructure for fast-growing internet businesses worldwide. Our platform processes millions of payments daily and operates in a highly regulated fintech environment, where security is a core product requirement — not an afterthought.
Our engineering organization builds and scales a complex cloud-native platform with over 120 microservices. As the company continues to grow, we are strengthening our security organization and introducing a dedicated Application Security Engineer role.
The mission of this role is to keep our business and revenue safe by building security into the way we develop software — from early design decisions to CI/CD pipelines and live production systems.
This is a hands-on Application Security role focused on embedding security into the software development lifecycle and reducing real product risks.
You will work closely with engineering teams to:
design secure application architectures
improve secure coding practices
detect vulnerabilities early in the development lifecycle
continuously improve application security as part of everyday engineering work
You will have a direct impact on how secure software is built across a large microservices ecosystem, influencing standards, tooling, and engineering culture.
