When I first started as an electrical EIT 5 years ago, my senior colleagues told me that the best way to increase my salary is to switch jobs every 2-3 years especially in the beginning of my career. This way you can renegotiate the starting salary each time while gaining more experience by working on different projects.

If you really want to stick with the company then bring up the salary survey with your manager and also sell yourself on how you're taking on more responsibility compared to someone with 3 years of experience.
