Work Mode
Flexible vacation and hybrid work model focused on results. Claridians in a hybrid mode split their time between working from the office, talking to or visiting customers, or working from home. We don't enforce a minimum number of days for most roles, but you're expected to spend time at the office organically, and be at the office most days during your ramp-up or when required by your leader.
