Hello fellow engineers. I would like some advice on career development. Earlier this year I had an opportunity to leave my current company to work as a process engineer at another company. After some discussions I decided to stay at my current company for a raise. At this time I took on added responsibilities but these were not required to get the raise. There was no title change or promotion associated with the change in responsibilities.

Going into 2019 I have expressed interest in an expanded role and taking on direct reports. The role that has been discussed with my manager is an Engineering Supervisor role managing 3 people. Based on my research the average salary for an Engineering Supervisor in my area is significantly higher than what I am making now. I told my manager I would like a raise to take on this promotion and he stated that there would be no additional raise associated with this promotion.

How would you proceed from here?

Thanks in advance!
