Aaron Whitman, 26, of West Bergholt, Essex, faces five charges, including inciting an underage girl to have sex.
He is also accused of misconduct in a public office while working for Essex County Council.
He appeared at Colchester Magistrates' Court where he did not enter a plea.
The charges date back to between July 2013 and September 2014,  when he worked as a business administrator for the council.
He was bailed to appear at Ipswich Crown Court in January.
A former council worker accused of using his position to gain contact details for a 15-year-old girl before propositioning her for sex has appeared in court.
