2 job offers: biotech research and food processing engineer

I need career advise. I am just graduating school and have 2 job offers. one is with a biotech research place, and the other is a production & food safety supervisor for a coffee manufacturing place. At first I was specifically looking for production supervisor jobs, so its cool I got it, but I have also been offered a job in biotech and I think working with cells, microbes, genes etc. is really interesting and neat. I am just concerned about the career direction with the biotech job, including long term pay scale, as I am not going to get a PhD, probably a masters in the long run of whatever direction I take.

my education background is petroleum engineer, and just graduating from a diploma in food and pharmaceutical science.

Follow what your heart says I always feel like fresh graduate nowadays should focus on the present as the future remains to be unpredictable. Exploring on which career you truly belong, gain new experience and continue learning.
