Vantaggi
The pay is genuinely absurd for Australia. We're talking US market rates, not "competitive for Melbourne" rates. There's a big difference and once you've experienced it you can't really go back. I've got mates at the big banks and consulting firms and the gap is wild.
Beyond that the work is actually good. You're not babysitting legacy systems or sitting in planning ceremonies all day. There are real problems to solve and you get actual ownership over them. Nobody is micromanaging you, they just expect you to deliver and if you do, you get more responsibility pretty quickly.
The people are good too. Everyone is switched on and actually wants to be there. That sounds obvious but it makes a huge difference day to day. No one is phoning it in.
Svantaggi
It's not a relaxed environment. If you want to leave at 5 every day and fully switch off, this probably isn't your spot. The pace is high and there's always more to do. Personally that suits me but worth knowing.
