TL;DR · Principal Security Engineer, Product & AI

As Marqeta’s Principal Security Engineer, you will lead product security engineering across their payment platform and build an AI security program as they scale generative AI capabilities. Your day-to-day involves threat modeling payment features, securing APIs, developing genAI controls, and ensuring coherent security standards across infrastructure and enterprise domains. You’ll work closely with Product Security, Infrastructure Security, and Security Operations teams to provide technical oversight for endpoint protection, network security, and more. Ideal candidates have over 10 years of security engineering experience, deep expertise in product security, and a strong interest in AI/ML security. Proficiency in Python or similar languages, knowledge of cloud-native environments like AWS, and familiarity with compliance frameworks such as PCI DSS are essential. This role offers the chance to shape how security scales across Marqeta’s organization through tooling and engineering partnerships.

  • Develop and maintain secure development lifecycle practices for APIs and services.
  • Build and implement security controls for generative AI and ML systems.
  • Provide technical oversight for endpoint, network, and enterprise security controls.
  • Mentor security engineers and raise the organization's overall security maturity.
  • Communicate complex security risks to executive and board-level audiences.

What we're looking for

  • 10+ years of security engineering experience with technical leadership across multiple domains.
  • Deep expertise in product security including threat modeling, secure SDLC practices, API security, and authentication/authorization design.
  • Strong background in AI/ML security, understanding risks like adversarial attacks, model poisoning, prompt injection, data privacy, and AI supply chain threats.
  • Broad fluency in infrastructure and enterprise security, covering endpoint protection, network security, identity management, and cloud security.
  • Proven ability to build security frameworks, tools, and programs from the ground up.
  • Strong programming skills in at least one language (Python, Java, Go) with experience reviewing code across multiple languages.
