What do jobs ads mentioning Julia really mean? E.g. this one from Ford and Facebook

A lot of job ads from companies mention Julia, usually with other languages mentioned, such as this latest one I see from Ford:

Experience with software development in MATLAB or a similar technical computing language (Python, Julia, C++)

Can anyone confirm Julia used at companies like Ford, Facebook and more here (I know of many potentially using Julia, some, actually using, may never have placed a jobs ad):

Meta (Facebook), Reality Labs, System Thermal Performance Engineer “using tools such as Julia or Python”

MIT Energy Initiative (MITEI), Postdoctoral Associate, “programming languages (e.g., Python, Julia, and MATLAB), and optimization packages (e.g., JuMP and Pyomo).”

Most of the national laboratories have job ads also listing Julia, and some seemingly make it pretty clear Julia, at least JuMP, already used or at least planned:

  • National Renewable Energy Laboratory,
    • Postdoctoral Researcher – Mathematical Optimization for Energy Systems, "Experience with Pyomo and/or JuMP "
    • Electricity Markets Modeler and Software Developer II/III, “Preferred Qualifications […] Julia / JuMP experience”[24]
  • Nvidia, Machine Learning Engineer - Reinforcement, “Experience with Lisp / Scheme, Python, Julia, and C / C++.”[25]
  • Oak Ridge National Laboratory, Postdoctoral Research Associate - Building Sensing and Control, “Preferred Qualifications: […] Demonstrated ability to program in Julia or Modelica.”

They mean what they say: they want someone with that experience. If you want more details about any particular job you should ask the hiring manager or just apply.

Why they would want someone with that experience could be because they’ll be using Julia or it could be because they’ll be using similar tools and programming knowledge (especially once you know more than one language, especially within particular domains like scientific/technical computing) is highly transferable.
