Arista Networks

Both target 3rd- or 4th-year Computer Science / Engineering students and are part- or full-time, with conversion to an ongoing graduate role available to strong performers at the end of studies. Applications go by email – resume and transcript to jobs@arista.com – against live requisitions rather than a fixed cohort window. Because Arista does not publish a cohort-wide application calendar, the work for a candidate is monitoring live postings rather than stacking a single autumn deadline against peer firms.

Three structural things on Arista's university page and October 2025 product announcement shape the early-career experience:

• Branded market leadership in 800GbE: Crehan Research, quoted in the October 2025 announcement, places Arista first in branded market share for both 800GbE and overall data-centre Ethernet switching, with 800GbE port shipments more than tripling sequentially in Q2 2025.
• Single-engineer printed-circuit-board ownership in hardware: each PCB design is the work of one engineer, from spec creation through schematic capture, layout, bring-up and manufacturing support; interns are routinely tasked with test-board designs that go into manufacturing lines.
• Twice-yearly "Hack-a-Switches" hackathons and an internal test fabric running over 20,000 automated tests per day, both stated on the firm's own university page.

The university page also states intern code "will end up in customers' hands"; scope per head is therefore high – a hardware intern ships a board, a software intern's code lands in production – but the product domain is narrower than at a full-stack hyperscaler, so the engineering depth is in networking and high-speed signalling rather than full-stack web infrastructure.
