。
She's satisfied with his current salary.
Literal
She [topic-は] his [genitive-の] current [genitive-の] salary [with-に] is-satisfied.
満足する ('be satisfied') takes the satisfying thing with に — a に-marked 'source of satisfaction.' The ~ている form marks the ongoing state of contentment. 現在 ('present, current') is a no-adjective; modifies 給料 ('salary') via の. 給料 specifically refers to wages, salary, or pay — distinct from 賃金 (wages, often hourly), 報酬 (compensation, often professional), or 月給 (monthly salary).
