About the Team

The Application Security Team plays a key role in protecting all software developed at Lending Club. This core team of application security engineers works closely with and in support of a large team of security focused software engineers all of which work to ensure Lending Club builds and maintains secure software for its customers and partners. As the Senior Application Security Engineer, you will focus on finding and fixing vulnerabilities, promoting good security practices, and solving classes of security problems through engineering solutions for both front and back end software. In addition, this team integrates tooling and automation, expert review, and training throughout the Software Development Lifecycle (SDLC) to ensure security is prioritized at each step to identify potential vulnerabilities and design flaws.

The ideal individual contains a blend of application development experience and application security experience. You can get your hands dirty to solve problems directly in the code and execute swiftly on complex problems.
