5. Information Technology Project Manager（IT 项目经理）

What they do: Keep big tech projects like software upgrades running on time--and on budget. "We bring order to chaos," says April Ellison, an IT project manager in the San Francisco Bay Area.

Why it's great: Lots of opportunity. "Just about all companies need techsavvy people who are great managers," says Houston tech recruiter Linda Ranostaj. Figuring out how to implement cutting-edge technologies keeps the job challenging.

Good upward mobility: IT project managers can rise to chief technology officer of a company, where the salaries can hit $300,000.

Do you prefer to work for yourself? The field offers plenty of consulting work.

Drawbacks: Hours (and hours and hours) of meetings. Aggressive project timelines. Staff jobs can be outsourced to consultants.

Pre-reqs: Five to seven years of technology and computer-related experience. A project management professional certification, along with an MBA, will enhance career prospects.

6. Certified Public Accountant（注册会计师）

What they do: Crunch the numbers, whether it's for financial analysis or tax preparation.

Why it's great: Businesses began stocking the payroll with CPAs after major accounting scandals earlier this decade, and a host of new corporate accounting rules going into effect soon should ratchet up demand further.

Government agencies are also hiring CPAs, to monitor how well companies are complying with the new regs. Add inevitable changes to personal income tax rules and you have a pretty recession-proof profession.

"Unless Congress does away with taxes, we'll always have work," says CPA Lisa Featherngill of Winston-Salem, N.C. Some 33,000 independent CPAs also work for themselves, typically as tax preparers.

Drawbacks: Deadlines are nonnegotiable; if you're in tax preparation, kiss your personal life goodbye between mid-February and April 15.

Pre-reqs: A certification exam and, typically, 150 hours of business and accounting classes and work experience.

7. Physical Therapist（物理治疗师）

What they do: Restore strength, flexibility, and range of motion to people who have been sidelined by injury, illness, or disease.

Why it's great: Unlike many health-care professionals, physical therapists generally see great progress in their patients. "I don't just treat the symptoms--I give people the tools to get better," says Jennifer Gamboa, an orthopedic physical therapist in Arlington, Va. Plus, there's no overnight or shift work.

Medical advances that allow a growing number of people with injuries and disabilities to survive are spurring demand, says Marc Goldstein, senior director of research at the American Physical Therapists Association. And hey, baby boomers' knees aren't getting any younger: An aging population means more chronic conditions that need physical therapy treatment.

Drawbacks: The impact of health reform on the profession is a wild card. Can be physically demanding.

Pre-reqs: A master's degree, plus certification and state licensing. Many employers prefer a doctor of physical therapy degree.

8. Computer / Network Security Consultant（计算机／网络安全顾问）

What they do: Protect computer systems and networks against hackers, spyware, and viruses. "I consider myself a cybercrime fighter," says Gregory Evans, an independent computer security consultant in Atlanta.

Why it's great: No company or government agency can afford to have a serious breach in the security of its computer system. New technologies and an unending supply of creative hackers around the world keep the field challenging. Consultants can often work from home. And top-level pros command big paychecks.

Drawbacks: Talk about stress. If a system is infiltrated by a virus or hacker, it could mean lights out for the security consultant's career. "This is a job you can't afford to ever fail in," says Evans.

Pre-reqs: Mostly major geekdom, since the skills can be self-taught. Still, a computer science degree comes in handy. An information systems security professional certification (CISSP) is increasingly favored. Experience is key for better-paying positions: Most companies won't hire a consultant with less than five years of experience.

Evans took a more unique route: He actually started as a hacker, but was convicted of wire fraud and conspiracy in 2002, served 16 months in prison and was ordered to pay more than $9 million in restitution and fines. After prison, he went the white-hat route, starting a security consulting business in 2003. That year, a chain of computer security stores contracted to sell his cyber security software. He has since done deals with the Atlanta Hawks and The City of Los Angeles.

9. Intelligence Analyst（情报分析师，唯一在前十名内的政府工作）

What they do: Gather and analyze data related to international policy and military strategy, most often for the government or defense contractors.

Why it's great: Like adventure? Data might be collected from satellite images, wiretaps, Internet chatter, and military and spy reports.

Given the country's continued vigilance about national security, demand should remain high. "The best part is helping our country," says Nate Copeland, an intelligence analyst in Herndon, Va.

Drawbacks: High stress; you often can't talk about your job outside of work.

Pre-reqs: Security clearance, of course. Foreign languages and often military experience are a huge plus.

10. Sales Director（营销总监）

What they do: Set and meet sales goals, generate new accounts, and mentor and train new recruits.

Why it's great: A successful sales director--especially one who can weather an economic downturn-- will always be sought after.

"I feel secure since I'm bringing money into the company," says Holly Anderson, a sales director in St. Helena, Calif.

Sales directors often move into high-level management.

Drawbacks: Sales down? You're vulnerable to getting the ax. Commission-based pay can fluctuate dramatically. Expect to be on the road about 50% of the time.

Pre-reqs: 10 years of sales experience and a year or two in management. A proven track record beats an advanced degree.
