Unfortunately, the room to develop outside of working at the support center is somewhat bleak. Being the front lines of handling Uber's messy situations is complimented with a standard customer service wage (see Google for average salary) and monotonous daily tasks.
Additionally, the work life balance is something talked about throughout the entire company. You'll notice that it applies to this position as well. Your sick days, personal days, and vacation days are all combined into one insufficient balance throughout the year. Depending on business needs, your typical holidays are not always promised either.
