Fortinet

The firm's main careers portal currently lists Summer 2026 intern requisitions across:

• US engineering and corporate tracks in Sunnyvale and Santa Clara, California (software development, AI / GenAI, tax)
• EU technical internships of around six months in Sophia Antipolis, France (product security, performance testing) and Brussels, Belgium (systems engineering)
• A recent-graduate pipeline that runs against the same requisition portal rather than a separate cohort

Programs are posted per-department rather than as a single firm-wide cohort, so a candidate is competing for a specific team's headcount rather than a central pool. Picking the right requisition matters more than at firms that route applicants centrally through HR.

The firm was named a Leader in the 2025 Gartner Magic Quadrant for SASE Platforms, an upgrade from the Challenger quadrant the prior year that independent trade press covered alongside Palo Alto, Cato and Netskope's positions on the same chart. For an early-career engineer this means the stack is unusually hardware-rooted: the firm's internship requisitions include roles testing physical appliances with traffic generators such as Keysight BreakingPoint and VIAVI, and fuzzing TCP/UDP protocols against FortiOS, not only SaaS engineering. That narrows the next-job set toward network-security vendors and infrastructure teams.
