We are currently seeking an experienced Compiler Engineer to join a security client of ours on a permanent basis. This exciting opportunity will involve helping transform the security industry, removing the need for traditional CAPTCHA

The role requires candidates to be based in the US, as the role is primarily remote, but will require quarterly travel to Indianapolis,

Key Responsibilities:
We are looking for a Compiler Engineer to help build a high-performance compiler written in Rust with selective components running in WASM. The compiler transforms JavaScript into a custom bytecode format that executes inside our own interpreter, designed for performance, portability, and advanced control-flow handling. You will work on the full pipeline, including parsing, IR transformations, optimization passes, and bytecode generation, while also contributing to the design and evolution of the interpreter itself.

Desirable Requirements:

  • Strong background in Compiler Engineering – should have experience building compilers from scratch
  • Experience with Rust and C
  • Expertise with browser engine architecture
  • Experience with writing decompilers for CAPTCHA systems would be a plus but not required

The role offers the flexibility of a remote work arrangement and offers long-term earning potential with a strong compensation package, including equity and bonus.
