Stop trying to control other people and start learning how to control yourself.

Avoid the burnout and keep the negative thoughts away
In fact I could be that other engineer (I'm not, but I'm in a very similar sounding situation)
I was the most senior engineer and first to join a new startup with a bunch of colleagues from an old work place. I put in ridiculously long hours for the first year and a bit to get the product started, and got completely burnt out and my family life suffered
After we brought on a few more engineers I reduced my hours to a more normal 40 hours a week, and made use of the flexible start-up hours to pick up my kids from school some days and come in late on others (A great way to manage the stress of being in a busy startup)
Now I also spend a lot less time writing code and more time managing product requirements, an overseas team, on system architecture, and all those dev-ops tasks (big time-sink) that no-one else wants to do
I don't completely know the original-poster's situation, but quite often the senior person on the team is often shielding the other developers from all the daily crap that is going on in a company so that they can be as productive as possible, and you might not be completely aware about everything that is going on
If you manage to resolve it, that'll look really good to the founder and could help the company succeed. If you fail, you still look good because you're trying to make changes to help the company.
We had an employee that was underperforming and would work the bare minimum. It turned out that he felt overwhelmed, so work was very stressful for him and he would duck out as a defense mechanism. We changed his role somewhat (internal tools dev instead of product, product manager working with partners, main handler of support issues that got past tier 1) and he was a lot happier and ended up working more hours and meeting goals.
Working at a startup/small company can be very difficult, so finding the right fit in a team can be the difference between burnout and success. If he likes what he's working on, he'll make time to get it done.
