My summer at Sierra Space gave me exposure to a fast-paced industry environment. I was given more independence than I ever had before, allowing me to take complete ownership over the success of my project.

I was tasked to protect expensive hardware that was susceptible to thermal stress and damage.

I set up thermocouples, then coded a monitoring setup for a user to see the exact temperature readings. To protect the hardware, I implemented thermal limits to shut off power if a certain temperature threshold was met.

I gained valuable experience testing my scripts with hardware in the loop. After multiple successful tests, I merged my code with the company code base for 24/7 hardware security.

With such little guidance on my project, I learned the value of communicating with others and doing it with confidence. I found incredible success when reaching out to other subteams, improving my knowledge outside of the project I was working on and giving me an understanding of how everything fit into place. As I pursue my MS degree at CU Boulder, I am continuing to work at Sierra Space part time. I am working on MBSE models for preliminary programs that Sierra Space intends to develop over the next few years.
