Ask HN: Is your job interesting?

Do you work on interesting problems on a regular (even daily) basis? That is, problems that require creativity and innovative engineering solutions that make you really scratch your head, and not problems that just require predictable business logic or gluing libraries together. On top of that, feel free to answer: where do you work? What do you work on? What's your job title? What's your academic/professional background that led you there? (What's the salary of someone in your line of work, if it's something well defined like a network security engineer or AI researcher?)
