Pros
Talent and tools - There are really smart, experienced people here to learn and grow as a tech from, we have a mix of opensource software in use which are of course transferrable and some internal tools. Any SRE can contribute to the tools and write as much, or as little code as you're comfortable with. There is a lot of opportunity to travel to different places, some SREs are rarely in the office, and some never go anything else.. Also the provided breakfast, lunch, dinner and fully stocked kitchens are also a bonus, and the onsite physio therapy, and massages. There is no micro management, I am left to my own work and no constant "check up" from a manager to "make sure I am working" but the support is still there if needed. A lot of the "work/life" issues in other reviews tend to be from Software Engineers, and not an issue with SREs (I had the same concern when starting) - the docs are surprisingly good as well.
Cons
If you like normal work "structure" ie a manager giving you tasks to do, and having regular "catch ups" to ensure you are actually working, then for you, Palantir could be a struggle.. Personally I can manage my own time, and work so this is a Pro for me.
