Software Job Title Hierarchy Sample

Wikipedia gives a good overview of corporate titles and under the hierarchy for Information Technology companies you have the following:

• Chief Executive Officer
  • Vice President
    • Senior Project Manager / Senior Product Manager / Senior Software Architect
      • Project Manager / Product Manager / Software Architect
        • Project Lead / Senior Team Lead / Senior Technical Lead
          • Module Lead / Team Lead / Technical Lead
            • Senior Software Engineer / Senior QA Engineer
              • Software Engineer / QA Engineer

While each company will have it's own naming convention and responsibilities for a role, they do seem to fall within this basic hierarchy.

Hope this helps you out some.
