I had recently joined a company with the title of "Frontend Engineer" when in the hiring process and correspondence with HR titled the role of "Senior Frontend Engineer."
In the offer letter, the function is stated as just "Frontend Engineer," and I didn't see that as an issue as I thought the senior title is just not usually written in the offer letter (this is my second company after I graduate).
Then on my first day at work, I realized in the HR software I am not in senior-level engineer, and the title is just Staff Engineer when there are people titled as Senior Engineers. I am being treated and compensated as a Senior Level Engineer, though (my coworkers consulted to me about client architecture, performance improvements, etc. even in the first few days at work).
I won't be concerning this if my new role is at FAANG or other more prestigious tech companies, but my current company is actually younger than my last company. My previous position before this was a Senior Frontend Engineer at one of the biggest tech company in South East Asia, I join my current company simply because they pay better and some personal reasons.
I think this situation could be bad for my resume because in the previous job, I was a Senior, and this makes me look liked I am being demoted.
So, Is this a big deal? Should I talk to my manager about this as soon as possible or later in the probation review?
This concerns me enough that I am preparing myself to look for other opportunities, later when I am close to ending my probation period.
