A mainframe developer has to be proficient in computer coding and programming and should be competent enough to develop, test, and support different computer applications. A developer should also have the knowledge of utilities and tools utilized in mainframe developments. Employers look for a combination of technical skills and right academic background while recruiting a mainframe developer, so the CV Format should also emphasize on both the aspects. It is advisable to put across the skills first and then state the technical competencies and the educational background in the CV Format. Technical skills should include expertise in mainframe platforms and technologies, proficiency in programming language such as C, C++, Java, .net, and ability to work on varied mainframe platforms like IBM OS390 and Unisys, knowledge of technologies like MS Visio, SQL, DB2, IMS DB/DC, etc. Remember to emphasize on a relevant bachelor’s and master’s degree in the CV Format to catch the attention of the employer.
