Singapore base already up and running 2.5 years.
Penang base imminent recruitment on-going for penang I believe.
Roster 8 on 6 off. Yes you overnight every night on duty.
Upgrade - Depends on your experience (Jet), Ability/Skill and keeping your nose clean....meet all those requirements 1-2 years perhaps. There is no seniority list.
Small company so you are not just a number which is good I think.
Seems good company.
