I applied TeamViewer an cleared the interview but feel like I got low balled on the offer with 58k Base 10% Bonus and around 15% RSU (TC approx 70k). I currently make a little more than that at my current company while only working 35h and all in cash. However the tech stack here is pretty old and modern technologies can barley be found. Would it be smart to stat at my current gig or try to advance in terms of technologies since I plan on moving abroad in the future and a newer tech stack could help that. I'll also try to negotiate a better deal. TC: 72k YoE: 2.5
If you're already employed, never accept an offer for less than your current TC. You have the flexibility to be patient and shop around. Be strategic.
You left out the most important thing in your post: “Opportunity Cost”. By staying put at a chill job that actually pays you more, you can keep prepping and shop around more, in hopes of landing an offer that will also be valuable experience and pays significantly more.

I wouldn't switch without a significant increase in TC unless you really want to leave for other reasons.
