The Role
At Cash, security is everyone’s responsibility, especially among engineering disciplines. Cash Security is a multidisciplinary team, closely aligned to the needs of the business. The team is composed of multiple engineering and governance teams, each specializing and collaboratively solving the security, privacy and governance needs alongside their partner organizations.

The Product Security engineering team focuses on protecting Cash App’s customer data throughout the product engineering’s technology stacks. This is a hands-on, engineering-driven security team, which aligns security engineers toward product teams, across the entire Cash App organization. They continually raise the overall trust of Cash App’s products by building high leverage security abstractions into the technology stacks our partners utilize. They collaborate on building these security infrastructures, design patterns, and guidelines, and accomplish our goals by treating security engineering as a discipline, offering our expertise to technical and non-technical stakeholders. Secondarily, they abstract bespoke security solutions into reusable infrastructure, sharing our learnings, best practices, and solutions across the organization. This team's mission is to empower Cash engineers to protect our customers’ data in every aspect of the product and data life cycle; by providing reusable primitives and scalable platforms.

• Design, apply, and develop security primitives to protect data.
• Identify and remedy potential security risks to our customers' data.
• Partner with product teams to implement relevant regulatory data privacy considerations.
• Help the engineers around you level-up on their own security reasoning and knowledge.
