PRINCIPAL SOFTWARE ENGINEER DUTIES CODE
You spend less time writing code and more time doing other things like improving process, architectural oversight, mentoring newer engineers, and interacting with other business units. Their goals are more general like improving cashflow or scaling 100-1000 times. Their projects are usually too large for a single team. They can exercise technical leadership through their experience and rank. A principle software engineer is a senior contributor. They keep a close watch on reusability, maintainability, and correctness. They know what the formal approach is to every problem and follow it step by step. A software engineer will have the skills to develop software efficiently. Senior engineers are known for their technical expertise and application of engineering theories, but principals engineers are associated with innovative development within their field and may prove theories or develop new theories. Principal engineers have a direct bearing on the image of their lab because they are experts and can impact their company's reputation. Senior engineers report to the leadership of their division, while principal engineers report to senior management. Senior principals are seen as leaders in their field, and are higher-level than principal engineers, who are more focused on the basics.
