Spelling is important in your résumé. Even in the modern world there are still people out there who will bin a résumé that doesn't have the acute accents on both e's. Spelling is still used as a measurement of general level of education by many even though such a measurement is not usually accurate. You could have ten years of education and experience, but some employers won't even let you in the door for a first interview if you spell "separate" with three e's.

If your spelling is not top-notch, do not rely on a spelling checker, either for the résumé itself or the covering letter. Many spelling checkers are not able to tell if a word is used correctly, thus they will let through incorrectly-spelt words that happen to match the spelling of another word. For example, spelling checkers cannot distinguish which of "weather", "whether" and "wether" is the right word to use in a particular sentence. Spelling checkers are also limited by the contents of their dictionary and may not recognise some technical terms even if they are spelt correctly.

I suggest that you have someone else who is a good speller proof-read your résumé and covering letter for spelling, grammar and punctuation.

In IT, a sound grasp of spelling is important if you are writing applications that are sold to the general public, or are writing library functions that are going to be used by others. It is less important for system administration, although it helps to have a dictionary on hand if you need to write a Message of the Day or emailed memo.
