Safety through simplicity...


The Fuzion language

example is

 squares := setOf ((1..10).map i -> i*i)
say "squares = $squares"
 1..10 | x ->
  if x squares
   say "$x in squares"
   say "$x not in squares"

fuzion language logo

squares = {1;4;9;16;25;36;49;64;81;100}
1 in squares
2 not in squares
3 not in squares
4 in squares
5 not in squares
6 not in squares
7 not in squares
8 not in squares
9 in squares
10 not in squares

Standard Library Engineer (f/m/*)

You will be implementing and maintaining the standard library of the Fuzion programming language, including basic data structures, I/O and networking, interfaces to other libraries (GUI, AI, etc.). You will explore standard library approaches in other languages such as Rust, Java, Python, Haskell, C#, C/C++, Scala, Clojure etc. and define approaches most suitable to Fuzion.

Experience in different programming languages

Compiler and Static Analysis Engineer (f/m/*)

You will be working on the Fuzion language implementation. In particular, you will be working with the intermediate representation of Fuzion programs working on the compilation to machine code or the interpretation of Fuzion programs. You will implement framework for static analysis of Fuzion applications or modules that analyze certain correctness aspects of the code such as the absence of run-time errors. You will use the static analysis framework to implement optimizations for the generated code to boost the run-time performance of Fuzion applications.

Experience or interest in static code analysis or compiler implementation

Experience with existing compiler intermediate languages such as LLVM, Java byte-code, WebAssembly, GraalVM, etc. is a plus.

IDE Integration Engineer (f/m/*)

You will be responsible for the user experience of developers working with Fuzion using their favorite IDE. You will ensure a seamless integration of the Fuzion tools into development environments including Fuzion syntax and auto-complete functionality in the editors, a tight integration with the Fuzion library and compiler, support for source-level debugging, support for refactoring tools at IDE level and the integration of other tools such as static analyzers.

Experience with IDEs such as Visual Studio, Eclipse, IntelliJ, etc.

Test and Benchmark Engineer (f/m/*)

You will be responsible for developing and maintaining tests and benchmarks for the Fuzion language, ensuring the correctness of its implementation and the different back-ends as well as enabling comparison to other languages and their implementation. Since Fuzion is still a young language and the tools are in an early phase of development, this position would most likely start initially as a part-time position that will eventually grow into a QA team within Tokiwa.

Experience with CI/CD tools such as Jenkins, GitLab, etc.
