$40/hour – Binary Rewriter / JIT Developer for Custom RISC-V CPU

Job Title: Freelance Project: Binary Rewriter / JIT Developer for Custom RISC-V CPU

About the Company:

Intensivate is a cutting-edge technology company located in Berkeley, CA, USA. They are currently seeking a skilled Binary Rewriter / JIT Developer to join their team on a freelance basis.

Job Description:

Intensivate is working on building a custom RISC-V ISA-compatible CPU that requires a binary rewriting or JIT tooling solution. The ideal candidate will be responsible for rewriting RISC-V binaries at the function/loop level and implementing a tool that enforces a custom “half-register” calling convention.

Responsibilities:

• Evaluate open-source binary rewriting frameworks
• Implement a tool for function callsite rewriting
• Clone/split outer loops for disjoint register sets
• Handle RISC-V specifics such as compressed instructions and linker relaxations
• Deliver a command-line tool + test suite for rewriting binaries

Skills Required:

• Strong experience with compilers and binary analysis
• Hands-on experience with LLVM IR or similar tools
• Proficiency in C/C++ or Rust for systems-level development
• Experience with RISC-V toolchains and ELF internals
• Prior work on custom calling conventions or binary translation is a bonus

Deliverables:

• Source code for the rewriter/JIT tool
• Documentation and examples for transformation
• CI test integration for validation
• Performance test results on provided binaries

Engagement Details:

This is a remote, part-time or full-time contract with an immediate start. The duration is estimated to be 2-4 months for prototype + refinement. Please be prepared to share examples of prior work, availability, and hourly/weekly rate.

Why This Remote Job is Worth Applying For:

Working with Intensivate on this project will allow you to be at the forefront of cutting-edge technology development. You will have the opportunity to showcase your skills in compilers, binary analysis, and system-level development while contributing to the creation of a custom CPU. This role offers flexibility, a challenging technical environment, and the chance to work with a highly skilled team.
