Troubleshooting skills. The most essential soft skill for a junior programmer to carry out their responsibilities is troubleshooting skills. This skill is important for the role because "an important part of a programmer’s job is to check the code for errors and fix any they find." Additionally, a junior programmer resume shows how their duties depend on troubleshooting skills: "involved in troubleshooting of front end issues with the seo results. "

Detail oriented. Many junior programmer duties rely on detail oriented. "computer programmers must closely examine the code they write because a small mistake can affect the entire computer program.," so a junior programmer will need this skill often in their role. This resume example is just one of many ways junior programmer responsibilities rely on detail oriented: "experience in java back-end developer with good command on object oriented design and principles. "

Analytical skills. Another skill that relates to the job responsibilities of junior programmers is analytical skills. This skill is critical to many everyday junior programmer duties, as "computer programmers must understand complex instructions in order to create computer code." This example from a resume shows how this skill is used: "worked on cascading style sheets and setting up data exchange with other websites using xml web services. "
