Pros
Co-workers are nice enough. The science and medical applications involved are fascinating, not that your opinion on those is desired.
Kontras
No opportunity to gain skills with CAD/CAE/MATLAB, FEA, PLC programming, Visual Studio, or other serious engineering resources. All of that happens elsewhere. Virtually no opportunity to gain skills with physical equipment such as logic analyzers, prototyping technologies, or machine shop equipment. Documentation, if you manage to get it from one of the multiple systems IBA has, in some cases is not adequately QC'd. Example: one subassembly update's functional description was mostly blurry photos of whiteboard notes from some meeting; that update had to do with linear motion stop/start of the subassembly's position in a particle accelerator; workers in different room made it move without realizing it; serious damage and delays ensued.
