I'll try to be elaborate to give a clear picture of what happens here, so they don't bait potential hires into the hole.
1) Claims to be a product development company, but is in fact service based serving one client - Dassault systemes. All the core R&D work is done in Europe and since the teams abroad do not trust the efficiency and capability of engineers in 3dplm, they provide you all the drudge work like not-so significant enhancements and bug-fixes, thereby stagnating your career and skill set.
2) You will never get freedom and the chance to propose your own solutions, since there is so much red taping between geometric, 3dplm and DS. Your proposal will be lost in the process. You won't even get the chance to learn the technology they develop there comprehensively since there will be reluctance from core teams abroad(as mentioned in 1)
3) The directors and senior directors for software R&D teams have background in mechanical engineering. You can imagine how they would lead and manage people from CS background. They have all learned from wiki, what "product development" is, and they will keep bringing that up in every conversation or concern you have regarding the technical road map. Basically, they want you to continue with drudge work till you get so dumb with your dried skill set that you have no choice but to stay there with knowledge of a single DS branded product(which you wouldn't even be a part of - development wise).
4) Almost all employees are from service background, so expect a similar work culture/environment.
