McLaren Engineering Group plans to expand to Bergen County in August.
Its office at 530 Chestnut Ridge Road in Woodcliff Lake will accommodate more than 250 employees.
The company signed a 12-year lease with Keystone Property Group. The location is near the Garden State Parkway at Exit 171 and close to NJ Transit rail and bus stations.
McLaren is also expanding its offices in New York City and Albany, N.Y., marine services operations in Rockland County, N.Y., and Liberty Landing Marina in New Jersey.
McLaren has recently worked on the Caven Point Marine Terminal in Jersey City, the mixed-use developments at 197 and 207 Van Vorst in Jersey City and the Pulaski Skyway Bridge in Kearny, among other projects.
