What should be my next steps?

I have been working for a small reconditioning transformer plant for about two months now and was wondering how to progress further into this career. The plant manager hired me to get my foot in the door, as I have no prior transformer tech experience. I have been working as the Single Phase Pad Mount Tech and I really do love the work and find transformers fascinating. I picked it up very quick and they are already talking about getting me on 3 phase units in a couple months. But I want to go further than that. Like becoming a journeyman in controls, relay tech or maybe becoming testing engineer. What steps should I be taking in the coming years to achieve this?
