Jones Day and Dechert are advising on the $429m (£328m) sale of jobs website Monster to HR consulting company Randstad.
Randstad, which is based in the Netherlands and has offices in 39 countries around the world, has acquired Monster in an effort to bolster its presence in the US.
Jones Day is advising Randstad on the deal with a large cross-border team led by M&A partners Ken Boehner, Daniel Mitz and Alain Dermarkar, and intellectual property partner Ryan Walsh in the US.
European lawyers working on the deal include M&A partner Marc Rijkaart van Cappellen in Amsterdam, Munich office head and employment partner Friederike Goebbels, and global disputes partner Johannes Willheim in Frankfurt.
Meanwhile, Dechert is advising Monster with a team led by corporate partners Martin Nussbaum and Derek Winokur in New York, alongside antitrust and competition partner Michael Weiner, employment partner Stephen Skonieczny and tax partner Steven Clemens.
The deal is expected to close later this year. If successful, Monster will delist from the New York Stock Exchange and operate as a separate offering under Randstad.
Other recent M&A mandates for Jones Day have included advising Atmel Corporation on its $4.6bn (£3bn) acquisition by Dialog Semiconductor, and its role acting for US fastening products maker Erico on its $1.8bn (£1.1bn) takeover by UK-based pump and valve maker Pentair.
