We are NYC based but remote friendly!

Hello, World! Codecademy has helped tens of millions of learners upgrade their careers, build meaningful projects and gain confidence in their skills with engaging, accessible, and flexible education on programming and data skills. We provide hands-on interactive lessons ranging from Python to R to Javascript and everything in between. Our learners have gone on to start companies, new jobs, and new lives thanks to what they’ve learned with Codecademy, and we’re thrilled to be working to take that impact to the next level.

Codecademy was started in 2011 by two college students in a dorm room at Columbia that were frustrated by the huge gap between education and employment. Almost a decade later, we are a rapidly growing, diverse team of 100+ headquartered in SoHo, NYC. We’ve raised over $40m in venture capital funding from top investors including Union Square Ventures, Kleiner Perkins, Naspers, Y Combinator, and more.

If you want to help build a business that impacts tens of millions of people each year and helps them lead better lives, join us!
