Senior Application Security Engineer

As a Senior Application Security Engineer, you’ll be a key security partner to our web and backend engineering teams, helping build security into every stage of the software development lifecycle.

You’ll work closely with a product portfolio to guide product security, with particular emphasis on AI/ML security considerations and collaboration with data science teams. From secure design and threat modeling to code reviews and vulnerability remediation, you’ll help engineering teams identify and address security risks early.

This role is ideal for someone who combines deep application security expertise with a developer-focused mindset. You’ll bridge frontend, backend, and API security while helping engineers solve complex security challenges and strengthen secure development practices across the organization.
