お疲れ様です acknowledges the other person’s effort. Use it with colleagues; with customers, stay with こんにちは and ありがとうございます.
Short answer: to say what you do, use your job + です (会社員です, “I work for a company”) or where you work + で働いています. Japanese offices run on set phrases: お疲れ様です greets colleagues all day, よろしくお願いします opens any request, and お先に失礼します excuses you when you leave before others. Business cards (名刺) are exchanged at every first meeting.
