The Application Security Engineer develops and tests security components that make an application more secure. They proactively test their security posture from an attacker's perspective, help shape engineering best practices, improve and drive application security monitoring, and work with the security team to educate engineers on emerging threats.

Application Security Engineers need to use tools like Java, Scala, Typescript, Python, and Javascript, coding and scripting, and security assurance tools. They also need experience securing public-facing endpoints and remediating vulnerabilities found in code.
