• Experience with LLVM (preferably) or cranelift internals and back-end specifics
• Experience working with Clang, Swift, or other projects that use LLVM
• Experience with JIT compilers, virtual machines, and their security implications
• Hands off work attitude that requires minimal supervision; being proactive and self-motivated for timely delivery of quality code
• Experience with comprehensive testing methodologies (unit test, integration tests etc)

Preferred Qualifications

• Experience with JIT compilation and low-level instruction sets a plus
• Knowledge of computer architecture, touching on cache management, virtualization and x86 instructions
• Publications in top tier Compilers or System Conferences such as PLDI, POPL, CGO
• Experience collaborating on an open-source project

We offer a dynamic, fast-paced environment where innovation and problem-solving are at the heart of everything we do. Here, your work will have a direct impact on the security and scalability of blockchain technology, contributing to the foundation of decentralized applications worldwide.

We're excited to welcome individuals who share our passion for pushing the boundaries of blockchain technology. If you're ready to take on the challenge and contribute to the next generation of blockchain infrastructure, we'd love to hear from you.
