Product Security Architecture (Threat Modeling)

Product Security Architecture (Threat Modeling)

Description

As part of the Product Security Architecture team, you'll help reduce security risk across

Dropbox by partnering with engineering and product teams throughout the software

development lifecycle (SDLC).

Our team focuses on security threat modeling, and consulting. We work closely with

product and infrastructure teams to identify security risks early in the design process,

provide practical security guidance, and help teams build secure systems. We also

develop tooling, documentation, and automation that improve the efficiency and

scalability of security reviews across Dropbox.

This role is ideal for a security engineer who enjoys solving technical problems,

collaborating with engineers, and helping teams make informed security decisions.

Responsibilities

Participate in security design reviews and threat modeling exercises for new

products, services, and platform capabilities.

Partner with engineering teams to identify security risks and recommend practical

mitigations during the design and development process.

Serve as a security consultant for product and engineering teams, answering

security questions and providing guidance on secure implementation patterns.

Review application and system architectures, technical designs, data flows, and

deployment models to identify security risks and recommend secure design

patterns

Partner with engineering teams developing AI and machine learning features to

identify emerging security risks and recommend secure implementation patterns.

Help maintain and improve security standards, guidance, reference architectures,

and internal documentation.

Develop or enhance tooling and automation that improve the efficiency of threat

modeling, security reviews, and risk assessment processes.

Collaborate with other Product Security engineers to perform application security

assessments and investigate security concerns identified during development.

Contribute to developer education efforts through documentation, office hours,

workshops, or security awareness initiatives.

Support security incident investigations and root cause analysis when application

security issues are discovered.
