Exposure to production systems is a new advantage you have. You can learn a lot from the failures and problems. If your workplace has written postmortems, read them. Ask more senior engineers about the times things went wrong. Figure out how to politely spectate, or productively involve yourself, when emergencies/incidents happen. Try to understand the pros/cons of the choices your workplace has made (people will certainly be whining about the downsides!). How could different choices have avoided the cons? What different downsides would those choices have introduced? (Be careful not to come off as critical. It's common to see, with hindsight, that different choices would have worked out better, and sometimes anti-social to point it out).
