Arup, which has offices in Leeds, Sheffield and York, is set to cut 350 jobs.
The engineering and design consultancy’s redundancies come as a result of the COVID-19 pandemic.
A spokesperson said that Coronavirus had solidified the need to reshape the business, based on anticipated forward workload, business size and skillsets.
The firm’s Sheffield office was the first Arup office in the UK to open outside of London in 1958. It is working with Sheffield City Council to help deliver the Sheffield Retail Quarter, a mixed-use redevelopment known as Heart of the City Phase 2.
The York office has been open since 2010, and the Leeds office since 1989.
