Radio Access Network Engineer



My road in life has been direct.
In high school, my strengths were in math and science, and I loved learning about new technologies.
In my first year of college, I enrolled in engineering courses but explored other majors, as well.
I enjoyed my engineering courses and clubs, so I chose to pursue a degree in mechanical engineering.
I did a couple of internships to get an idea of what it is like to work in different industries.
Applied to AT&T because I was interested in their technology development program.
Received a job at AT&T upon graduating, and I'm now learning about new technologies and designing.

My work combines:
Problem Solving

Day to Day

My workday mostly consists of design work. My projects allow me to design or improve parts of the cellular network. I utilize various computer programs to perform my work. It is common to discuss ideas or gather information from different departments. Meetings are usually scattered throughout the week. Some meetings are informational, while others are focused on collaboration.

Skills & Qualities Beyond School

Problem solving skills and creativity are necessary as a design engineer. One must be able to identify problems or improvements and think creatively to come up with solutions. Time management and organizational skills are needed, too, in order to manage large amounts of information and multiple projects.

Advice for Getting Started

Here's the first step for high school students

It is important in high school to develop a strong foundation in mathematics and science and to take an interest in technical hobbies. Having a strong foundation in mathematics and science will enable one to excel early on in there college career. A radio access network engineer designs systems of electrical equipment, so participating in a technical hobby/club is great for becoming familiar with technology and how it works.
