It's a boom world for the workers in some of these tech sectors.

ENTERPRISE software, customer relations management and aerospace designers will be in high demand this year by Southern California tech companies, according to high-tech talent and outsourcing firm Yoh Services LLC.

Yoh interviews hundreds of hiring managers and job seekers in compiling the list, and there were some significant changes from last year when companies were still investing heavily in Sarbanes-Oxley compliance, according to Jim Lanzalotto, Yoh's vice president of strategy and marketing.

Now, data projects that have been on the back burner for a couple of years will come to the forefront given rise to demand for different skill sets in the software arena.

"Customer relationship software is becoming much more important," he said. "Companies have data banks of customer information, and they're trying to cross-sell all of it."

Another change in the list was renewed demand for aerospace engineers. That follows a few years of layoffs in the sector. Aerospace jobs didn't even crack the top 10 list in 2004 or 2005. "We believe the aerospace market is going to have a continued renaissance," Lanzalotto said. "Boeing has had a huge influx of orders. The defense industry will have a bump this year."

Rounding out the top-10 high demand tech jobs were enterprise resource planning software specialist (SAP, Oracle, PeopleSoft); customer relationship management consultant; data warehouse architect; net developer; aerospace design engineer; clinical project manager; hardware engineer; firmware engineer; clinical research associate; and data manager.
