Pluspunten
I got tons of great experience working on an awesome launch vehicle. I was challenge daily, never bored and developed both soft and technical skills. Really the work and the mission is amazing, they just have little respect for the majority of their work force when it comes to fair compensation and work/life balance. It's worth noting that in addition to crafting work instructions I was also heavily tasked with tooling design. SpaceX is the kind of place that values competence and hard work and titles mean very little. If you are good at something they will not stop you from doing it and will even encourage it even if it's far outside of what your job description is. This is a blessing and a curse because they absolutely want you to grow as an employee but they will not compensate you fairly for your efforts and can fall back on your official title to limit advancement opportunities that would cost them in salary.
Minpunten
I remember towards the end of my stint there working on a Sunday, which coincidentally was my 28th-straight day of work. That day I sat at my desk and balled my eyes out for 15 minutes as the stress had finally broken me. I decided then and there that I had to find another job. Note: They do not pay overtime for salaried employees or offer any kind of comp-time or other compensation as a general rule. Saturday rotations are usually mandatory. Production is a brutal place to work at SpaceX.
