A Software Engineer Co-Op is a student or recent graduate who participates in a cooperative education program, gaining hands-on work experience at a company while still in school. These positions typically last several months and allow students to apply their classroom knowledge to real-world software development projects. Co-Ops work alongside experienced engineers, contributing to coding, debugging, and project development, and often rotate between academic terms and work terms. This experience helps students build their skills, expand their professional network, and often leads to future job opportunities.

As a software engineer co-op, you work with today’s latest and greatest technologies, researching Database Theory, JavaScript, CSS3, HTML5, and more. Your responsibilities are those of a student and intern, and you research and develop software. Your duties may include completing a project, assisting engineers, or shadowing them to develop the skills necessary for entering the workforce. Co-op positions often last for a term of one year. Students almost always receive pay for these positions that either provide credit or a pass/fail grade.

Your responsibilities may also include participating in agile team meetings, collaborating with cross-functional teams such as QA and product management, and learning industry-standard tools and workflows. While the scope of your work may start with smaller tasks, strong performance can lead to more complex assignments and greater autonomy as your term progresses.

Strong problem-solving abilities, willingness to learn, and effective communication set standout candidates apart. These skills ensure you can contribute to real-world projects, adapt to new technologies, and collaborate effectively within engineering teams.
