These days I would say you should get into OS development and learn about unikernels. Linux should be a solved problem right now and the future would be in OSes that don't have interrupts enabled and you have full control over the CPU cores.

`Linux should be a solved problem right now`

This is a joke right? Unix is not even a solved problem and it's been around 50+ years.

I see I’m currently programming mostly in python at my day job do you any good resources i could consume to gain more knowledge on OSes

This is not a joke: Read the Intel manual, maybe check out some of the learning repos on github that solves all the glue-stuff that isn't important. I have one such repo here:

Thanks for sharing that Out of curiosity do you work for trading firms

Andrew Tanenbaums book is good for the theory. Real world is a bit blurred so it's also worth reading about some modern development like eBPF (very handy for tracing too)

I started learning kernel internals from these books, I highly recommend all of them.

Operating Systems: Three Easy Pieces (free online) - Arpaci-Dusseau

Linux Device Drivers, 3rd ed (o'Reilly) - Jonathan Corbet

The Linux Programming Interface - Michael Kerrisk

The Design and Implementation of the FreeBSD Operating System (2nd ed) - McKusick, McKusick, Watson

Solaris Internals - McDougall, Richard, Mauro

For ultra low-latency trading, I'd look into FPGAs before going that route.
