Uber on Monday announced 350 job cuts focused on its self-driving car unit, recruiting and customer support.

The cuts, the third round in recent months, were focused in the autonomous vehicle unit, operations, recruiting and customer support, Uber said. Since July, the company has cut more than 1,000 jobs, more than 2 percent of its work force.

Uber's stock performance has been disappointing, with its price down about 30 percent since the first day of trading.

The layoffs have been received favorably by the company's investors, who have been worrying about the company's difficulty to report profit. They have questioned the strength of Uber’s ride-hailing business, while the company has pointed to its growth in its secondary businesses, including food delivery.

In August, Uber reported a record quarterly loss of $5.2 billion while it also experienced its slowest-ever revenue growth.

Last week, Uber announced its intent to acquire the grocery delivery company Cornershop.

In July, Uber laid off 400 people from its marketing department. And in September, it cut 435 people from its engineering and product groups.

Uber’s self-driving car unit, the Autonomous Technology Group, or A.T.G., was spun out from Uber in April after a $1 billion investment from SoftBank, Toyota and the Japanese automaker Denso.
