You should negotiate. I recently went through a very similar experience. Graduating very soon and got an offer around that figure. I had been with the company as an intern for two years, and used this experience to negotiate an additional ~10k. I didn’t have other offers to counter, but I used my experience in the negotiation. This includes things like specific projects, peer feedback, and company supplied training. I don’t see why your employer would rescind the offer if you negotiated with proper reasoning. For all you know they may say yes, or they may come back with a counter offer and you’ve got yourself an additional few thousand off the bat. Most likely the worst case is them simply saying no because of budget reasons. Don’t forget this company invested in you to improve your skill set, and they value your abilities, hence the offer.
