## About the Role

You enjoy helping people and take responsibility for getting thingsworking. You can debug a network or operating system problem, writescripts and use APIs, and explain what happened clearly. You care aboutthe details of both the systems you build and the experience of thepeople using them.

Experience with device management, identity systems, and networking isuseful. We care more about your judgment, curiosity, and ability tolearn than a particular certification or number of years in IT. Youshould be comfortable moving between hands-on support and writingsoftware that prevents the next problem.

## Description

C5R builds research facilities for frontier models: physical environmentswhere models can design experiments, operate instruments, learn fromresults, and be evaluated on real scientific work.

We build facilities end to end, bringing together the physical site,instruments, robotics, software, and operations. By working closely withmodel developers, we continuously produce the data and physical feedbacktheir models need for pretraining, lab-in-the-loop post-training, andevaluation., We need an IT engineer to make the systems our team relies on simple,reliable, and secure. You will own the computers, accounts, networks,and office technology that let people do their work, and write softwareto make those systems easier to operate as we grow.

 * Computers and devices: provision and manage Appleand Linux machines. Build reliableenrollment, configuration, software deployment, and patchingworkflows, and help people troubleshoot when something breaks.
 * Identity and access: manage Google Workspace,single sign-on, and access to company services. Make onboarding andoffboarding straightforward, with the right permissions and a clearrecord of who has access to what.
 * Networks and office systems: maintain switches,Wi-Fi, VPNs, and conferencing equipment. Work with our infrastructureengineers to keep office and instrument networks reliable and makeremote access to equipment easy to use.
 * Security and recovery: manage device encryption,endpoint protection, backups, and recovery testing. Turn securityrequirements and audit evidence collection into repeatable processes.
 * Automation: write tools that connect our systems,track equipment, and eliminate repetitive work. Keep configurationand scripts in version control, test changes before rollingthemout, and document how to operate and recover the systems you own.

We think from first principles and take the time to understand a problembefore building the solution. We prefer boring, well-understood technology(Linux, Postgres, HTTP) over clever or fashionable alternatives, and webuild our own tools when off-the-shelf options would cost more than theysave or provide a mediocre experience. We use AI liberally to write code,but we design and maintain our algorithms and architecture judiciously.
