Customer.io powers automated communication that people actually want to receive. We help teams send smarter, more relevant messages using real-time behavioral data.

This program outlines a 10-week People Operations internship designed for a college student interested in the world of HR.

The program is built on a simple premise: the best internships are structured enough to give confidence and open enough to give real ownership. The intern will leave having done actual work — not just observed it.

The program is anchored in People Ops as home base, with structured rotations into People Experience and Recruiting. A deliberate ramp curve means the intern spends the first weeks learning before they do, and the final weeks doing with genuine independence.

The duration of this internship will be from June 29, 2026 to September 4, 2026.

• →Support day-to-day People Ops tasks including onboarding, offboarding, and HRIS record maintenance
• →Participate in rotation days across People Experience, L&D, and Recruiting — observing, asking questions, and documenting takeaways
• →Own one capstone project end-to-end: scoping, stakeholder interviews, deliverable, and final presentation to leadership
• →Communicate proactively in a remote environment — weekly updates, flagging blockers early, and coming prepared to every check-in

• A natural curiosity about people — you find yourself wondering why workplaces work the way they do, and you care about making them better
• Someone who takes initiative in a remote environment — you don't wait to be told what to do next, and you communicate proactively without being asked
• Highly organized and detail-oriented — HR work lives and dies on accuracy, and you take pride in getting the small things right
• A strong communicator, both in writing and in conversation — you can ask a clear question, give a thoughtful update, and know when to speak up
• Comfortable with ambiguity — this is a startup environment, and some days will look different than planned. You adapt without losing momentum
• Open to feedback and genuinely eager to learn — you don't need to have all the answers, but you do need to be willing to grow
