Core C Developer Full-time

Your job would be to work on all aspects of the main Tor network daemon and other open-source software.

As a core developer, your job with Tor Project will be to work on all aspects of the main Tor network daemon and other open-source software. This would include triaging, diagnosing, and fixing bugs; looking for and resolving security issues; occasionally dropping everything and scrambling to implement last-minute anticensorship schemes or deploy urgent security updates; and working collaboratively with coworkers and volunteers on implementing new features and protocol changes at every stage from design to maintenance.

We are working to make our code more scalable, testable, and maintainable. You would be reviewing other people’s code and designs, looking for ways to improve it. For an idea of the breadth and depth of the work you’d be doing, please see ChangeLog file from the Tor source distribution.

This is a full-time remote position. Flexible salary, depending on experience. Experience and/or passion for working with open source communities and/or a commitment to Internet civil liberties are added pluses for any candidate applying for this position!
Expected skills and experience:

• 5+ years’ experience in C and several other programming languages
• Solid understanding of secure C programming issues
• Comfort working remotely and managing your own workflow with limited supervision
• Experience and comfort interacting with users, coworkers, and team members online
• Ability to comfortably drive the entire lifecycle of a new feature in an existing piece of software from design, to implementation, to testing, to maintenance
• Experience and comfort with peer review of your own code and design, and with your reviewing of others’ code and design
• Transparency! As a non-profit, everything Tor Project does is public, including your name and pay rate

Desired skills and experience:

• Knowledge of cryptography basics: be able to understand how to implement our protocols and discuss changes to them (the ability to actually implement block ciphers and stuff like that is not necessary)
• Sufficient level of networking knowledge to understand how to implement our protocols and discuss changes to them
• Experience with high-performance networking code
• Experience with open-source software development, including working over email and IRC with a globally distributed teams of employees and volunteers of varying skill levels
• Basic familiarity with distributed version control systems
• Familiarity and experience with non-blocking, event-driven networking programs
• History of significant code contributions to multiple open-source projects
• Experience with development on Microsoft Windows
• Genuine excitement about Tor and its values! Follow this link to view the Tor Project social contract.

Other notes:

• Academic degrees are great, but not required if you have the right experience.
• Tor developers don’t have an office; you can work from wherever you want, so you need to be comfortable in this environment! We coordinate via IRC, email, and bug trackers.
• We only write free (open source) software, and we don’t believe in software patents.
