We know where the jobs are today — and we definitely know where they aren’t. But what about in 10 or even 20 years?

As things like technology, medicine, science and environmentalism continue to advance in the coming years, several occupations are bound to emerge. By understanding these trends, job seekers can play a more active role in planning for their careers.

Some are speculative, some are definitive — but here are 10 potential jobs of the near or distant future, based on the trends:

1. Cyber security specialist

Cyber security is a growing industry. Knowledgeable professionals who can protect websites and expose hackers will be a hot commodity in the coming years.

 2. Genetic counselor

Genetics are advancing at a rapid rate. Doctors can now run tests that will predict genetic conditions, and soon, parents may be able to choose the sex of their unborn children. With the help of genetic counselors, families can educate themselves on available genetic technologies and options.

3. Organic food farmer

Organic food currently occupies about 10 percent of the food and beverage market — and it’s only going to increase. As a result, more organic farmers and producers will need to improve organic farming techniques and grow the food.

4. Medical records administrator

Medical records are at the forefront of innovative technology, with a strong push to digitize medical records. An increased number of medical researchers will be needed to help transition records from paper to digital, and to be able to navigate records quickly for patients.

5. Mobile application developer

Remember car phones? You know, the equivalent of a cell phone, except that you could only use it in the car and it was the size of a brick? With the development of phones like the BlackBerry, Android and iPhone, the mobile media industry is continually progressing. An increased number of developers will be needed to help develop applications, in addition to combating security and compatibility issues.

 6. Robotics technician

Robots are becoming more commonplace and they don’t run on their own. Technicians will be needed to build robots, maintain them and keep them from malfunctioning.

7. Simulation engineer

There’s a simulator for nearly everything these days, from surgeries to flying to drinking and driving. As more simulation-based technologies follow suit, engineers will be required to help out.

8. Social media manager

Social media is the new “it” profession. It started with Facebook, Twitter and LinkedIn and has expanded to many other platforms. Organizations are now employing social media managers to oversee their online communities and enhance/protect the company brand.

9. Stem cell researcher

Although it’s a controversial topic, stem cell research is gaining ground. If this continues, more researchers will be needed to develop cures for diseases, genetic enhancements, and the other information these cells may potentially hold.

10. Sustainability officer

Sustainability has become a concern around the world and also among businesses. Since the executive suite may not have time to learn all there is to know, organizations are hiring eco-savvy individuals as “sustainability officers.” These folks will find, research, and implement eco-friendly policies to benefit the organization.
