Yep, use the best tools for your job. Sometimes that won’t be Julia. I’ve worked in many languages for many reasons — even in cases where Julia would’ve done better technically but couldn’t be used due to other reasons (like existing toolchains and codebase and inertia) — and that makes sense.
Want to work more in Julia? Target areas where Julia is undisputedly the best tool for the job. Learn ModelingToolkit and SciML. Learn Turing’s modeling syntax and how to use it in real-world contexts. Learn mathematical optimization with JuMP.
That’s how you find jobs that use Julia or convince your team (and boss) to use Julia. And if you’re having trouble convincing your boss, that’s what I do for (part of) my day job. JuliaHub is built to help reduce friction in workplaces — things like compliances, validation, inner- and open-source package management, collaboration, etc.
