The role in plain terms

You drive product security for Zeta's platforms: threat modeling new features, reviewing code and architecture for vulnerabilities, running application security testing, and partnering with engineering teams to build security into the development lifecycle. Fintech stakes apply - these systems move money, so correctness and rigor matter more than speed.

What the employer asks for

These requirements are quoted from the employer's listing, kept in their exact words so eligibility details are not distorted:

Who this role suits

Application security engineers with a few years of secure-SDLC experience, especially anyone with fintech or payments background - PCI DSS context is a real plus here. Strong fit for developers moving into appsec with strong code-review skills. Not for infrastructure-only security profiles.

Practical notes

Prepare a threat-modeling walkthrough for a real system, and OWASP Top 10 plus API security patterns. Banking-domain awareness - card data, PCI scope - strengthens your case. Zeta works from Hyderabad; the listing is on-site.
