Staffing; Procedure; Airport
We were landing at LAX prior to the late night runway configuration change. We were cleared to land on 25L; a [widebody] aircraft [aircraft Y] was put on the runway with a line up and wait then cleared for takeoff. The [widebody] aircraft was VERY slow to power up which gave us minimum separation for landing. We landed right in [aircraft Y's] jet blast. Upon further review; I found that there was only one Tower Controller at the time working all 4 runways at LAX. One person working both the North Complex and South Complex at the 3rd busiest airport at a critical time at night is EXTREMELY dangerous and needs to be looked at!
B737 First Officer reported landing with minimum separation behind a departing widybody aircraft at LAX. After landing he learned that the entire airport is being routinely controlled by one Controller during late night operations.
