Job Description

The Role:

This is an amazing opportunity to work with Markets Information Security Team at ION. As a Product Security Engineer, you would be the key enabler of secure and compliant products. This role reports to the Product Security Lead and partners closely with engineering and product teams to increase the overall product security posture. You will own and scale product/application security by embedding security into the Secure SDLC, automating controls in CI/CD, and driving measurable risk reduction. The role is hands-on: you will perform security-focused code review and targeted testing, strengthen API security, implement supply chain security (SCA/SBOM) practices, and run an efficient vulnerability lifecycle with clear SLAs and metrics.
