YOUR ROLE

The Security team at Zip is responsible for protecting the confidentiality and integrity of our customers' data. As a Security Engineer, you'll take on a dynamic, high-impact role focused on securing the cloud infrastructure that Zip runs on. You'll lead efforts to harden our AWS environment, build foundational security guardrails, and launch key initiatives that solidify the trust customers place in us. Your contributions will be pivotal to the success of Zip's rapid growth as we launch new products, such as AI Agents and an App Marketplace, and enter new markets. We move quickly to solve a wide range of complex technical challenges.
