they may consider their current offerings to be "next gen"
The actual job description mentions "Knowledge on latest technology node (FinFETs, 20nm, 16nm) is a plus".
Granted, thats not definitive, but common sense dictates this cant be for the current design. You wouldnt go through the process of hiring a new lead engineer at this late stage, that makes no sense whatsoever; With time this critical it could never yield a better result than continuing with the team you have. A qualified new lead engineer is not likely found and able to start working the next day, if you publish this job posting today, you probably wont have anyone working for you for another 3 months. So even if your entire team died in a plane crash, you would still rather contract a company that has a well oiled team in place, instead of hiring people and building your own.
Mind you, its entirely possible their schedule is slipping, but these job openings have nothing to do with it.
I thought this company had the most extensive industry connections of all the ASIC hardware manufacturers, though? That's definitely what they're major selling point was originally. In most other ways, what they presented was little different to the other players.
