An existing or prospective employee might inquire about a 401K.

A 401(k) plan is a retirement savings plan offered by many US employers which features tax advantages for the saver. It is named after a section of the US Internal Revenue Code (IRC). The employee who signs up for a 401(k) agrees to have a percentage of each paycheck paid directly into an investment account. The employer may, or may not, match part or all that contribution. The employee gets to choose among several investment options, usually mutual funds. You will probably need professional help!
