Our Mission and Vision

At Solidgate, our mission is clear: to empower outstanding entrepreneurs to build exceptional internet companies. We exist to fuel the builders — the ones shaping the digital economy — with the financial infrastructure they deserve. To achieve that, we’re on a bold path: to become the #1 payments orchestration platform in the world.

We believe the future of payments is shaped by people who think big, take ownership, and bring curiosity and drive to everything they do. That’s exactly the kind of teammates we want on board.

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.

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.
