Join a team to build high-performance systems handling a large portion of Internet traffic, focusing on protocol performance and contributing to open standards and open source.
Hiring will be focused on those residing within the greater Austin, TX metro area. It will be a hybrid role, with the expectation of 2 days per week in the office.
Systems Engineer, Network Protocols & Distributed Systems Location: London, Lisbon or Austin (Hybrid)
Join the team helping shape the future of the Internet. We're building high-performance systems that handle a quarter of the Internet's traffic. Our work influences open standards (like QUIC, MASQUE, and ECH), involves close collaboration with the IETF, and pushes the boundaries of what's possible in networking and security.
You don't need to be an HTTP or cryptography expert to join - we're looking for excellent engineers who love tough problems, want to learn deeply, and are excited to contribute to one of the most technically demanding areas of infrastructure.
