What hard/technical skills are most important for senior customer support engineers?

Dr. Thomas Gilbar Ph.D.

Chair and Lecturer, University of West Florida

There are quite a few hard/technical skills that are important for Computer Engineers. We've found a lot of managers are looking for comfort in a variety of programming languages, including C++, C#, Java, Python, etc. Also, try to have a background in a variety of operating systems (certainly windows and mac, but also having experience on Apple iOS, Android, and even Linux will give you a leg up on the competition). Having at least some experience in data/cyber security is also important these days. On the hardware side, programming and applying microcontrollers and VHDL/Verilog programming are extremely important. VLSI design is also a nice addition to skill sets, though in most cases, not a deal-breaker. Circuit and electronic design are also very important skills to supplement your microcontroller skills.
