The Hack team is a group of programming language and type system experts who are responsible for evolving the Hack language (hacklang.org), its developer experience, and Meta's large codebase of Hack code. Our mission is to “make Meta engineers the most productive in the world through safe and expressive languages that work at Meta’s scale”, and because we own the full stack, we can innovate in ways and at speeds that set us apart.

Software Engineer - Programming Languages Responsibilities:

• Improve language’s syntax and semantics to be more expressive and safer for our users
• Integrate AI into our developer workflows
• Build richer static analysis to find and fix issues that Meta engineers experience
• And, doing all of the above at a mind-bogglingly large scale: we operate on a codebase with 100s of millions of lines of code
  
  

Minimum Qualifications:

• Bachelor’s degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience)
• Academic background in programming languages and type system theory
• Industry experience as an applied scientist, engineer or similar role, studying and developing programming languages
• Experience in bringing research results into production
  
  

About Meta:

Meta builds technologies that help people connect, find communities, and grow businesses. When Facebook launched in 2004, it changed the way people connect. Apps like Messenger, Instagram and WhatsApp further empowered billions around the world. Now, Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to help build the next evolution in social technology. People who choose to build their careers by building with us at Meta help shape a future that will take us beyond what digital connection makes possible today—beyond the constraints of screens, the limits of distance, and even the rules of physics.
