My longest term job: instrument scientist for the Spitzer Space Telescope. I specifically work on IRAC, which is the “short” (3.6-8 micron) wavelength camera. I was responsible for the design of the calibration methodology, processing, and scheduling. While the spacecraft was shut down in 2020, I am still involved in various science programs based around Spitzer, and I still field technical questions about it.
Various Spitzer science projects I have worked on, most of which are still on-going in some form:

SWIRE
S-COSMOS
GOALS
IRAC Dark Field
SpARCS
