Simultaneous operation of groupby and resample on pandas dataframe?

Update Pandas 0.21 answer: pd.TimeGrouper is getting deprecated, use pd.Grouper instead.

mean_agg = (df.groupby(['JOB_TITLE',pd.Grouper(freq='5AS')])['BASE_SALARY']
              .mean())

mean_agg.unstack('JOB_TITLE')

Instead of using resample, let's try to use pd.TimeGrouper

mean_agg = (df
      .groupby(['JOB_TITLE',pd.TimeGrouper(freq='5AS')])['BASE_SALARY']
      .mean())

mean_agg.unstack('JOB_TITLE')

TimeGrouper aligns the bins of the grouped time range.
