Here you will have increasing responsibilities, mentoring junior programmers as well as getting involved in the overall design and implementation of the software. While you should still expect to be involved in coding, you may also have a more customer-facing role where you might have to train the users (internal or external) of your software. At this point, your focus should be on transitioning to a more managerial track, with further education and certifications leading to the same.
- Architect — At this stage, with 10+ years of experience in the trenches, you could have an architect-level role which include duties of interfacing with the customers and clients of your software, collecting and analyzing requirements, and responsibility for the overall architecture of the system. You may also take on an increasingly managerial role, including interfacing with upper management.
- Manager — You are now into the management track, possibly equipped with one or more managerial training and certifications under your belt. Your duties here include overall responsibility for software delivery, financial management and budgeting, and interfacing with senior management.
