Syn is probably going to a lower down engineer, who just recently moved from electrical engineering to doing mechanical, specifically laser tech. They coukd definutely work for the same company/whatever even if slightly differeng fields. I have a sort of idea - Syn has a mechanical arm so if Nax is in the whole merging of tech and medicine then there's a connection there. Possibly they met when Syn first got the surgery for the arm and sort of kept in contact after that?
Computers and hacking is obviously also an option - while I'm assuming hacking is probably illegal, and the stuff Syn does will probably be that, she also does more legal programming and working on AI in her free time. I don't really mind
