Minnesota Job Descriptions

Hardware Design: Wireless, Audio

Location:

Minneapolis MN

Company Description:

This is a privately held well-known manufacturer of hearing aids, with over 4000 employees in 20 countries. In my view, given US demographics, the hearing aid market is a solid growth market even during a recession. This company is on the forefront of creating portable audio devices involving cutting-edge audio, digital signal processing, and electrical engineering technology. The company is actively growing and offers a career growth path. The benefits package is among the best that I have encountered. Turnover is exceptionally low here. Although the company is privately held, there is a stock bonus plan that HR can explain. The company is located not far from Minneapolis. I have long admired Minneapolis/St. Paul for its rich cultural offerings, when one considers that Prince, Prairie Home Companion, and the Minneapolis Symphony are all there, and that's probably just the tip of the iceberg. Housing costs are significantly lower than in Silicon Valley or the inner Belt. Local cities offer parks, golfing, and good schools. The company is proactive in sponsoring visa candidates.
