I do agree with you that working in a small group or company has a lot of benefits, However, the salary is not that high as bigger companies. But also from my experience, I do learn a lot in smaller companies as more resources is open and usually, people work there have multiple hats and you get involved in a lot more than your role duties. For me, it is good for the learning process and builds my career, but for long-term future and stability, I would like to transfer to one of the big companies. In my personal opinion, it is the tread off between salary and learning curve and has a more solid background to be involved in more that one role and exposure to different things.
