What You'll Do

As a Principal Language Fuzzing Engineer at Epic Games, you will be at the center of our mission to develop a new language for coding game experiences at metaverse scale.

In this role, you will

  • Build a large scale fuzzer for a new programming language implementation
  • Evolve the fuzzer as new language features or compiler optimizations land
  • Add hooks to the compiler and runtime to make it more fuzzable
  • Leverage the language's executable specification to build a differential variant of the fuzzer
  • Work with the compiler team to develop a strategy for continuous fuzzer bug fix workflow

What we’re looking for

  • Proficiency in one or more programming languages
  • Experience building and maintaining large scale fuzzers
  • Track record of finding security bugs at scale using fuzzers
  • Understanding of security best practices and modern exploit techniques
  • Demonstrated ability to communicate fluently in English (written and verbal)
