The company says it is making every possible efficiency to create an "agile" future for the business.
The car giant, which has its engine manufacturing centre at the i54 north of Wolverhampton, is to spend about £2.5 billion annually on electrification, low carbon and digital technologies
In comes in the same week the company committed to its UK plants and revealed a huge investment in a zero-emission future.
The luxury car maker said it had begun to inform salaried staff on the detail of the organisational review which is designed to slash costs and create a more "agile" business.
A statement confirmed its hourly-paid manufacturing workers would not be affected by the cuts which, the company said, would be completed next year as its transition to an all-electric fleet by 2030 gathers pace.
A spokesperson for the company said: "This week's announcement outlines our future strategy not only including plans for our brands and vehicles, but also how we will reimagine our entire business.
"This will be a journey of permanent adaptation, but as we start to become an agile organisation, it's imperative that we make every possible efficiency right from the start, including finding the right baseline cost for our workforce.
"With a renewed imperative to prioritise value creation through quality and profit-over-volume approach, we will create a flatter structure designed to empower employees to create and deliver at speed and with a clear purpose."
The company says it needs to reduce the cost base to achieve a lean foundation, which will allow it to transform most effectively into a more agile organisation.
JLR cut 1,000 jobs in 2018 and 4,500 positions in January 2019 as it revved up plans to return to profitability following a run of weak demand for cars globally.
In the run-up to, and during the Covid-19 crisis last year, it revealed 1,600 jobs were to be lost.
JLR signalled it was too soon to know how many roles would be affected in its home UK market but out of 37,000 global employees, only 7,000 of them are based abroad.
