One company. Electronics and Systems under one roof.

Both branches are ParallelCascade. The split is for clarity: electronics and IC design remain the core, and Systems takes on operational complexity that needs hardware, software and AI in combination. If the work crosses both, that is fine.

Either door is fine. Electronics and IC design remain the ParallelCascade core. Systems handles operational complexity (custom software, hardware and AI solutions) where generic tools do not fit. In that case, all the better.
Not sure which door?

Send the problem, not a polished brief.

If the work crosses hardware, software and operations, that is fine. The split is for clarity in the market, not a wall inside the company.
