Lending Club



San Francisco, CA, US


The Security Engineering Team plays a key role in protecting all software and systems at LendingClub. This core team of security engineers works closely with and in support of a large team of security focused software engineers all of which work to ensure LendingClub builds and maintains secure software for its customers and partners. As the Application Security Engineer, you will be consulting and performing security assessments on key projects, 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, performs 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.
