What can I do as individual when there are not productivity incentives?

So why should I be more productive if I'm just going to have more work to do with no bonus?

What do you think? should I change my mindset? if yes, what are the reasons?

It's a good question to ask yourself. If you don't feel like you are being compensated for going above and beyond, there's no incentive for you to work harder, except for intrinsic motivation.

If you are feeling short-changed, and your company can't compensate you for your troubles, it may be worth it to explore different companies.

On a non-compensation level, I do think that it's more fulfilling to push yourself more to grow technically, otherwise, you'll stagnate and get bored. If you are working the same number of hours a day, you might as well be working on something that pushes you more because there's a rush to doing something challenging.

It might be an interesting exercise for you to think more about what you are looking for in the next 3/6/9/12 months. If you have a goal, like performance review or interviewing at a new company, you can work backwards to think about what kind of narrative you want to present during these evaluations. What would really make you proud and stand out against everyone else?

Ah, this is the classic scenario. If you feel like your company doesn't reward you at all for getting more stuff done (no higher performance review rating, no additional bonus/raise, no promotion), then it sounds like you should funnel that extra time into either interviewing, building side projects, and/or enjoying your personal life more.

Things get interesting when you do feel like the company rewards you for doing more work. There's actually 2 options here:

1. Finish it early and get more of the same kind of work - Again, if the company rewards you for this, you will come out ahead.
2. Use that extra time to create scope - This is what I recommend for you as a senior engineer. Instead of doing more of the same type of work (this can get you higher ratings but usually not a promotion, especially for Staff), look for bigger, more exciting, and more challenging opportunities. Think of it as building an internal side project for your job. Here's a good case study example: [Case Study] Building A Meta Internal Tool To Empower An Entire Org: Staff Promotion Story

Alex and Charlie had some pretty good comments. One question I have as a follow-up is across what time frame do you need to know that you feel under rewarded? There’s the ‘too long’ spectrum where this engineer probably wait way too long to switch , but I also think it’d be a bit too short-sighted to expect your efforts to be rewarded in a month. So where’s the sweet spot?
