Part-time Math and Science Tutor

CK-12’s mission is to provide free access to open-source educational content and technology tools that empower students as well as teachers to enhance and experiment with different learning styles, resources, levels of competence, and circumstances.

To achieve this noble and ambitious vision, we at CK-12 are challenging the traditional model of education to transform it dramatically. Technology has opened up lots of opportunities to revolutionize education for the benefit of students, teachers, and parents.

We have chosen to be non-profit so that we can effectively realize our mission and we can do the right thing! It also provides us the ability to experiment with big and bold ideas. CK-12 is backed by Vinod Khosla, a renowned technologist, and philanthropist.

At CK-12, you’ll experience the benefits of working in a dynamic, entrepreneurial, innovative, and non-bureaucratic environment where you will get a lot of cool things done that you might never have imagined! We are a small group of passionate folks who are determined to disrupt the current form of education. We came together from companies such as Apple, eBay, Amazon, McGraw-Hill, and startups.

Technology is key to scale education, and we deeply believe in it. Come develop great solutions on our cloud-based (AWS) AI-first platform delivering rich and interactive content.
