SEATTLE — Engineers in the Bay Area. Advertising managers in Chicago. Freight specialists in Arizona. The job listings keep piling up at Amazon, a company that is growing in many directions amid one of the tightest labor markets in memory.

On Monday, Amazon said it had 30,000 open positions in the United States, including full- and part-time jobs at headquarters offices, technology hubs and warehouses.

Although the company has positions to fill across the country, Amazon’s job boards list many more openings in the Seattle area and California and by its new campus near Washington, D.C., than it does anywhere else.

The vacancies, which Amazon said it hoped to fill by early next year, are permanent jobs and do not include seasonal positions for the warehouse workers and drivers that the company typically hires to handle the spike in orders it gets around Christmas. More than half the jobs are tech oriented, and roughly a quarter are for warehouse work, the company said.
