Role: Compiler Engineer (Rust)

We are looking for a Rust developer with experience working with compilers or transpilers to join our team in London. You will be building the core system responsible for translating COBOL code into modern Java.

Responsibilities:
* Design, develop, and maintain compiler and transpiler components using Rust.
* Work closely with Large Language Models (LLMs) to enhance the accuracy and efficiency of code translation.
* Collaborate with a small, focused team to build and scale a system capable of handling large, complex legacy codebases.
* Analyse and understand COBOL language structures and semantics.
* Implement intermediate representations, code generation, and optimization passes.

Technical Skills Required:
* Strong proficiency in Rust development.
* Demonstrable experience working on compilers, transpilers, interpreters, static analysers, or related language processing tools.
* Solid understanding of compiler construction principles (parsing, AST manipulation, type checking, code generation).
* Familiarity with LLMs and their application is a plus.
* Experience with COBOL or Java is beneficial but not required.

Ideal Candidate:
* Holds a passion for compilers, language design, and tackling complex software engineering problems.
* Has 3+ years of relevant software development experience.
* Enjoys working in a fast-paced startup environment (YC S21).
* Possesses strong problem-solving skills and attention to detail.
