My first thought is that this is the sort of problem managers are supposed to help with. If yours is a good one, raise the issue with him. Failing that, my thoughts:
It sounds like the position you want doesn't exist at your company. The next steps:
1) Figure out exactly what you want to do. Write specs? Write the most difficult code? Mentor other engineers?
2) Look carefully to see if the position exists after all, with some non-obvious name.
3) If not, figure out what employer or class of employer would have such a position.
