BIND 9 Software Engineer

We are looking for a Software Engineer to work on BIND 9. In this role, you will be a core contributor to a highly impactful, open-source project that powers a critical part of the global Internet infrastructure. BIND 9 is the most widely-used Domain Name System (DNS) server on the Internet, relied upon by operators of the DNS root system, Internet Service Providers, and global enterprises. Our team actively contributes to developing the Internet standards for DNS, and BIND 9 serves as a reference implementation of those standards. If you are passionate about building reliable software that keeps the Internet running smoothly, we would love to hear from you. What You Will Do Collaborate: Partner with our team to design and build new features for BIND 9. Maintain Quality: Participate in constructive code reviews to help us maintain a robust codebase. Problem Solve: Investigate and resolve bug reports from our global community of users. Deliver: Assist with release engineering and project planning to ensure smooth deployments. Support: Participate in our on-call escalation rotation (only after an onboarding and training period). Shape the Future: Represent ISC and participate in community organizations like the IETF to help develop future Internet protocols. What We Are Looking For (Note: Research shows that underrepresented groups are less likely to apply for jobs unless they meet exactly all requirements. If you are excited about this role and have relevant experience, even if you don't check every single box, we encourage you to apply.) Programming Experience: Strong skills in a procedural or object-oriented programming language (C, C++, Rust, etc.). C-Language Readiness: BIND 9 is written in C11/C17. You should have an understanding of modern C or a strong willingness to learn and adapt to it. System Familiarity: Comfort working within Unix/BSD/Linux operating systems. Communication: Conversational spoken and written English to collaborate with our international team. Self-Direction: Motivation and reliability to thrive in a remote, work-from-home environment. Team Spirit: A commitment to fostering an inclusive, respectful, and supportive team culture. Valuable Additional Skills (Nice to Have) Experience with C development (specifically C11/C23). Practical experience operating BIND 9 or knowledge of the DNS protocol. Familiarity with Git and open-source working environments. Knowledge of multiprocessor programming or theoretical/practical networking. Experience in network programming (e.g., libuv) or cryptography (e.g., OpenSSL). Experience with Python.
