HFT and finance are still mostly in-office. If you join as a front-office dev on a trading team, chances are you will not be remote much and people will be in the office trading.
This is a wild overgeneralisation but in descending order of fun levels/friendliness of HFT teams it goes Chicago, London, Singapore, NYC.
Seems to hold across most HFTs I have met/worked at. Not sure about hedge funds or other finance roles.
Edit: Crypto HFT firms also abound but they are generally more remote-friendly than TradFi (the latter have regulators that need you to have an office and stuff).
