First and foremost I don't think it would be a good fit on the grounds that the goal of the players is to ensure humanity remains extinct--if your bot had a strong desire for mankind's return he'd have joined up with the compelled. Also keep in mind that Boston Dynamics built you strictly for the purpose of being a home appliance; you are able to learn (And have had more than a decade to do so) but not any faster or with less practice than a human being. Part of the reason the world is falling apart is that it's been incredibly difficult for all these bots to replace field professionals. Speaking of replacing people....

Any robot that's designed to replace a human in the workforce is going to be purpose built and function more like an automated tool than individual. If a hospital were well funded enough to have an automated surgeon it would most likely be a ceiling mounted ((and unintentionally menacing)) device. That actually brings up a good point on military/security robots. Aside from simpler minds they adhere to a different code of conduct:

1. A robot will not harm authorized Government personnel but will terminate intruders with extreme prejudice.
2. A robot will obey the orders of authorized personnel except where such orders conflict with the Third Law.
3. A robot will guard its own existence with lethal antipersonnel weaponry, because a robot is bloody expensive.

So for the most part much of the military, police force and private security sectors still have serious hardware guarding their stockpiles.

All that said time for some more idea building!

While being a robot means you don't have a gender in the classical sense that just wasn't marketable, as such you came factory standard with both a male or female outward appearance and appropriate gender identity. In practice this means you're either a gynoid (female) or android (male)

I'm going to be fairly generous in what you can have for after market modifications with the caveat that no one character is more powerful or useful than the rest. These are all going to be semi-reliable homebrew gadgets at any rate.

With modern manufacturing mainly in shambles there has been a resurgence of low-tech weapons, if you decide to have a gun remember that ammunition is precious. You aren't likely to have more than a handful of rounds. (There's been plenty of shooting these past twelve years)

Save the few spots where your kind has managed to eke it out in settlements nature has reclaimed man's empty cities. Wolves, wild dogs and the growing number of species that escaped captivity are a real and present danger.
