Plinterns wrapped: Summer 2026

Plaid’s Summer 2026 internship program brought university students into engineering and new-business sales roles across its San Francisco, New York, and Raleigh offices, where they worked on customer-facing features, machine-learning infrastructure, data systems, authentication flows, sales outreach, and go-to-market projects. Engineering interns described end-to-end ownership of projects involving AI-assisted development tools, LLM evaluation, inference optimization, observability, distributed infrastructure, compliance features, and product onboarding, while sales interns gained experience prospecting, qualifying leads, leading discovery calls, supporting account executives, and communicating product value through customer stories and data. Participants emphasized a culture of mentorship, cross-functional collaboration, autonomy, and practical learning, with managers highlighting interns’ contributions to production improvements and longer-term product decisions. The program also included team offsites, volunteer activities, social events, and opportunities to build relationships across the company.
