There are some misleading points, so adding some additional info.
(1) All the recruitments are linked to the formal SEGA recruiting site (https://www.sega.co.jp/recruit/). So I guess all of the job offers are active and up to date.
(2) The detailed job offers are numbered, if we assume that the numbers corresponds to the positions available, we can guess that they are recruiting two character modelers, and one for each roles.
@HarmlessSyan said in Who is working in this game?:
Not 100% sure whether they updated the page or not, but it sure look about the same
I agree with you that these look as the same as the last year, still I haven't checked up the details so not sure if these are identical. The current recruitments are numbered from 7 to 14, so maybe these are wave two of their recruitments.
(3) The total size of the PSO2 team is pretty big. At the point of Episode 3, it was over 200 (https://www.famitsu.com/career/guide/companyvisit/1158).
It seems that the team is not only made from employees of SEGA, but also includes staffs from other companies. Another old article, but this is about a company sending 7 staffs to the team at the point of Episode 5 (https://www.e-xtreme.co.jp/solution/sega/)
(4) There are a lot of "in charge of" phrases used in the translation of OP. As English is a second language to me, I'm not sure about the exact nuance, but if this phrase implies that the person will be responsible for all about that area in PSO2 team, then the translation is quite misleading. For example, if the translation "You will be in charge of server program development work for the 'Phantasy Star' series" can mean SEGA is recruiting for someone taking the lead of the server development of PSO2, that's almost a mistranslation. They are just recruiting a staff working for server development.
From these points, I personally don't think these recruitments are of a critical importance to the development of PSO2. If all these jobs are filled, that would certainly speed up the development, but I wonder if that improvement is something we can feel.
