In-person is strongly preferred, but remote is a possibility for the right person -- there are a couple of employees who work full-time remotely.
If you're looking for something less formal, here's information about volunteering and helping to make exercises:

Read the project’s introduction
Khan Academy Exercises
Khan Academy has created a generic framework for building exercises. This framework, together with the exercises themselves, can be used completely independently of the Khan Academy application.
This repo consists of two parts:
Various HTML files that describe exercises.
A jQuery plugin for generating a usable, interactive, exercise from any of the HTML files.
Current Status
Khan Exercises is no longer used for development of new exercises at Khan Academy. We're always looking to improve the exercises that are currently built with Khan Exercises, but at this time we don't intend to add any new exercises. New exercises on Khan Academy are written by many content experts using Perseus and stored in our datastore as individual questions.
The bulk of our bug reports now go into Zen Desk where volunteers surface issues to KA developers, but we still process issues and PRs that come in through this repository. The goal is to keep high-quality bug reports and feature requests in this repository so awesome OSS developers who want to help KA have the tools do so.
If you're looking to contribute time, looking through our wiki is a good place to start. Questions should go into the issue tracker (we may set up gitter if there ends up being a high volume of questions).
Licensing
Copyright (c) 2015 Khan Academy
The exercise framework is MIT licensed.
The exercises are under a Creative Commons by-nc-sa license.
Using the Framework Locally
You need to serve the files from some sort of a server. You can't just open the files directly in a browser. For example:
cd khan-exercises
python -m SimpleHTTPServer # or python3 -m http.server
Now if you open your browser to http://localhost:8000 (or http://127.0.0.1:8000/) you should see the contents of the khan-exercises directory. Navigate to the exercises subfolder, and an HTML file under there to see an exercise.

We're working as fast as we can to fix any bugs that pop up, so we'd appreciate reporting any issues using the "Report a Problem" link at the bottom of every exercise page.

77 points · Open discussionKhan Academy has had exercises for a while now. It's probably one of the best open source projects to work on, in terms of impact and how easy it is to contribute. You only need to know HTML and a little JavaScript. The exercises are modular, so you don't need to understand the whole codebase in order to work on it. Plus, saying "I've contributed to Khan Academy" is a pretty cool thing to put on a resume.
For all the upvotes Khan Academy gets, though, there really aren't that many contributors. I'd encourage everyone reading this with an afternoon to spare to try writing an exercise for KA.

Remember, it's open source[1], so don't hesitate to join in and help revolutionize education. There's some very cool and interesting things we're working on that get used by millions of kids (and adults!) everyday. You know some js, python, HTML/CSS? Interested in documentation, searching for bugs, or doing usability testing? You're cordially invited.
