Tech Analyst vs DevOp Engineer

Hello I'm an undergraduate student, and I have two job offers. Please give me some advise for choosing a position for longterm career. I'm pretty interested in both position, but my goal is getting a SWE title. This time, I failed to get it so that I have to choose one of them. If I choose the bank company, I have a good opportunity of learning trading and big Data. Base Salary and Bonus of DevOp Engineer position at IT company is 30K higher than Technical Analyst position at a bank. The companies are both good, but IT company might be bigger than the bank. Which position is better? Please~~ Thank you for your time!
