Location

This is primarily a work-from-home role, but candidates should reside in the Philadelphia area and be available to come into the office when needed.

Clearance Requirement

Candidates must successfully pass an FBI background investigation and be able to obtain and maintain FBI clearance.

If you enjoy hunting threats, engineering better defenses, and working on a team where security is treated as a mission rather than a checkbox, we’d like to talk.

All candidates are subject to a drug test and a background screening.

Vertical Screen, Inc is an equal opportunity employer. Qualified candidates will be considered in a non-discriminatory manner without regard to legally protected characteristics.
