# Internet Freedom Nonprofit Seeks Software Engineers for Applications Team (Browser and VPN)

The Tor Project, Inc., a 501(c)(3) nonprofit organization advancing human rights and freedoms by creating and deploying free and open source anonymity and privacy technologies, is seeking two experienced developers to work on the Applications team.

Our Applications Team’s main project is the Tor Browser but we have plans to develop other apps in the near future. We are looking for two (2) full-time developers to join our team to help us with both Tor Browser development and mobile app development. These two positions share a core set of skills, but each has its own set of specific skills as well. However, regardless of whether you have all of one set of skills or a combination of the two sets, please apply! Further, if you feel that you meet several of the requirements, or could meet them with a little support, we would love to hear from you.

The team coordinates both synchronously and asynchronously via IRC, email, bug trackers, and some voice meetings. A personal commitment to free and open source software, good communication and documentation skills, and passion for contributing to the greater good are all essential.

These are full-time, remote positions. Salary for these positions is $100k USD and there is voluntary opt-in salary transparency for employees and contractors.
