## About the Role

targeted patches happen, andyou'd spend far more time running productioninfrastructure.) We're hiring for both rolesand are happy to advise you on which might fitbest. We don't expect you to come in with deepexperience; we're happy to hire smartproblem-solvers and teach them what they need toknow. But the job leans much more towardengineering than a traditional operations role:relentless automation instead of manual toil, anda large body of in-house technology rather thanonly off-the-shelf tools. You'll buildsystems, not just operate them. About you We don't expect you to have a background infinance or any other specific field - we'relooking for smart people who enjoy solvinginteresting problems. We're more interested inhow you think and learn than what you currentlyknow. You should be: Knowledgeable about operating systemfundamentals, computer architecture, and systemsprogramming concepts like sockets, virtual memory,and the process life cycle Able to understand network protocols at
abasic level Comfortable at the command line of aLinux machine (whether from coursework, sideprojects, or time spent administering a campuscomputer lab) and fluent in basic introspectionand troubleshooting: system health, individualprocesses, logs Someone who solves problems by writingcode (in any language) and cares about robustsoftware engineering Intellectually curious, collaborative,humble, and eager to learn (including frommistakes) Agricultural, Forestry & Food Sciences,Architecture, Urban & Environmental Planning,Computer Science, Data, AI,Economics & Management,Engineering & Technology,Life and Health Sciences, Medicine,Natural Sciences & Mathematics,Society, Politics & Interdisciplinary Studies #J-18808-Ljbffr

## Description

changes to theplatform, like upgrades, migrations, capacitychanges, and rollouts, planned meticulously andexecuted carefully The problem space runs from the physical to theabstract: datacenter provisioning andorchestration, kernels and drivers deliveredthrough Nix and RPMs, production and researchstorage at scale, cloud that integrates cleanlywith our on-prem platform, and, in partnershipwith our IT and Network Engineering colleagues,Linux desktops and how our hosts participate inthe network. We see Linux Engineering and SoftwareEngineering as two ends of a spectrum, and plentyof people could do either job well. LinuxEngineering is likely the better fit if you treatLinux itself as your problem space: you likeworking close to the operating system, you want tolook after production infrastructure, andyou're happy spending more of your time in aconsulting capacity than a typical developerwould. (Compared with kernel development, theemphasis flips: you'd rarely develop thekernel itself, though
