I've worked on many things in many capacities, but in all those situations my role was most simply: Designer.
You can over-complicate this stuff or get too concerned with the classifications (Interactive Design, UI Design, and Product Design, etc.), but to me it's all design (the verb). It's doing the work. Understanding the problem, the people who face that problem, and the constraints at hand. Then devising your best solution, executing it to a high level, and measuring the results.
Each problem is different and requires a different approach, so I try not to get too caught up in process or methodology chasing. Sometimes you need to add something, sometimes you need to take it away. Sometimes you need a system improvement, or technology advancement, other times you need a business or structural change.
It's all about finding the right balance. If I do all of the above well, with taste and care, — if it works great and feels right and is clear and understandable and makes someone's life better — I've done my job as a Designer.
