What is the ruling on a woman working as an online translator, and what does that entail in terms of speaking with clients via phone or messenger?

It is permissible for a woman to work as a translator, provided she adheres to the Sharia guidelines when speaking with non-mahram men. This means the speech should be serious, devoid of softness or submissiveness in tone, and limited to what is necessary. This is in accordance with the Almighty's saying: "Then do not be soft in speech [to men], lest he in whose heart is disease should covet, but speak with appropriate speech."
