Third personal pronoun of "be" ( for itemized list)

Hello,

I am making a job responsibility list for staff of a project.

I am using a form in which I omit the subject and start sentences with a verb in third person pronoun for responsibility b/c there are multiple responsibilities for one position.

E.g. )
Leader - Supervises staff
- Keeps the key to the studio
- Trains staff

I want to state "Be responsible for the entire operation of the project" in the manager's responsibility section, classifying him from subordinate leaders.

In this case, with what verb and in what form can I start the sentence?

I find it is tricky with "Be" because "becomes responsible" sounds little odd to me?

Thank you for your help.
