What are some good words that employers look for? Much of that depends on the field in which you are searching. However, action-based verbs are critical in appropriately and proactively describing what you did/do for an organization.

Make sure your tenses are correct. Use strong verbs such as: organized, developed, implemented, produced, increased (revenue, sales), decreased (costs, overhead), minimized, encouraged, supervised, spearheaded, designed… 

These are powerful words that make a difference! Employers are looking for such things as documented success, excellent provision of customer service, and a candidate who is boldly able to state what he/she can contribute to the overall productivity and success of an organization.
