I agree with the above - especially about the key points of escalating the bullying issue to higher authority and working with leaders to find out why you are not advancing/what you can do.

Based on OP, I'm guessing that you may have facilities outside of the team lifelines to support your experience in design and metalwork. If so, you may be able to use this to your advantage. Next design cycle (whether off-season or next build season), quietly take a design or prototype task for "homework". Pitch the idea/design as an example/prototype. Doing it this way, leaders will see that you have the ability to do these design or construction projects, even if they do not use your design. If you blow your horn but don't get too braggy about it, a team lead or two will probably request your help with something soon.

Should you find yourself a team leader in a year or two, give back. Make special efforts to learn people's abilities and utilize them to the benefit of your team and its members.
