I joined a startup where if you added all their experience together I'd still have 20 years more experience than anyone in the company at the time I joined. And this isn't the only time I have put myself in this situation intentionally. Short answer is no, never have I felt bad about it and I absolutely love being around smart people so it doesn't matter if I have more years doing the work. My answer to you is you are playing a role, that role is a team member with certain responsibilities, do your part. The team lead has their responsibilities, if you have more experience doing his/her job and feel he/she is lacking in an area offer your guidance privately but be humble. The key to mentoring anyone at anytime, is be willing to offer your experience and advice but don't be offended if they don't take it. Many times advances are made because someone is naive and does not fully understand the problem they are solving. Personally, I also love hearing new ideas on how to solve things that have been done in various ways before as it fuels new thought for me too. That doesn't mean I won't challenge ideas I know have failed in the past to get them to think through it. I also look at it as inspiration from someone who doesn't have some of the preconceived notions I might, which helps me stay fresh, inspired and thinking out of the box to solve problems. In the end it is up to you. You have your role on the team, play your role, if you don't like your role, change it (e.g. find another job etc). It really is that simple.
