Deciding

So I've been fortunate enough to receive multiple offers for summer 2026. For context, I am a sophomore undergraduate who is trying to go into ECE/computer science-related roles. I have received two offers from mid-large sized startups. The most recent offer is an aerospace company that's based in Los Angeles, CA. Summer 2026 will be their first batch of interns, and they currently have around 50-100 employees according to Linkedin. The total pay for me as an intern is $30/hour (No housing) and I haven't received too many details on overtime, insurance, or any other benefits. I received this offer more recently, and they told me I had about a week to respond. It seems like really interesting work, and it is definitely a field I want to go in. For the second startup, it's the first offer I've received for this recruiting season, and I have technically already done all the onboarding. It is mid-sized with around 150-200 employees. Pay is $50 in San Francisco, CA with health insurance, housing stipend and travel benefits. The work is also really interesting, and is a field that can feed directly into machine learning/robotics. Both roles are career paths that I want to pursue, and I have about 5 days to decide how to ask for a push-back to fall 2026 for the most recent offers. How can I go about doing so? Any advice for this type of situation? I feel as if it is hard to renegotiate on these companies due to their size.
