Who this role suits
Students and recent graduates who want hands-on experience. Internships are usually judged on curiosity, projects and coursework rather than years of work history.
How to prepare your application
- Check your résumé against the listed skills (Search) and give each one a concrete example: what you built or achieved, not just that you used it.
- Put one or two projects near the top of your résumé, with a link a recruiter can open in a few seconds.
- Revise core fundamentals for the role; early-career interviews lean heavily on basics and how you reason through a problem.
- Read what Perplexity publishes about its product or team, so you can say clearly why this role and this company.
- For remote roles, show that you communicate clearly in writing and can work without close supervision.
Apply only on Perplexity's own site. A genuine employer never asks candidates for money, deposits or bank details to apply, interview or “secure” a job. If something looks wrong, use Report a problem with this listing and we will review it. Read how we check listings.

You’re eager to learn and improve: you’re willing to put in the work, develop your skills, and get better every week.
You’re comfortable working in English: in a collaborative, professional environment.
You thrive in a high-performance environment: you’re comfortable with high standards, direct feedback, and a fast pace.
You’re willing to challenge and be challenged: You’re comfortable asking questions, sharing your perspective, and pushing back constructively when it matters.
