As an auditor, you have almost 100% ownership over your work. Usually a hierarchy at a team is staff > senior > manager > director/partner. Even though you are a staff of a team, you will be asked to have ownership. Especially, you will be expected to understand the purpose of each procedure you are performing and how to interpret the result of your work. If you find a deficiency during your work, your senior, manager, and partner will listen to you and bring the issue to the company with you.
It would be similar for a consultant.
