As far as I'm aware, you can negotiate during an internal transfer, especially if you’ve got strong experience like you do. It’s definitely worth asking about moving to L5, especially since the recruiter mentioned you’d have a strong shot at it. You could say something like, “Given my experience as a TPgM, I think I’m already operating at L5. Would it be possible to consider me for that level?” As for the salary, if the comp is projected to stay the same (L4 to L4), you can still ask for a bump, especially since the new role may come with more responsibility. Try something like, “I noticed the comp is similar to my current role, but given my experience and the new role’s responsibilities, I’d love to discuss aligning it with L5 market rates.” Just be ready to make the case for why you’re already at a higher level, and it doesn’t hurt to mention market comps. Best of luck with the transfer!
