The Role

As a C++ Systems Developer on this project, you'll be instrumental in building the runtime infrastructure and contract enforcement mechanisms that form the backbone of our verification system. You'll work at the intersection of modern C++ language features, compiler technology, and formal methods, implementing the systems that translate mathematical specifications into executable runtime checks.

This is a rare opportunity to work on cutting-edge compiler technology while contributing to the future of software verification.

Key Responsibilities

• Design, develop, and maintain high-performance C++ systems code for verification infrastructure
• Implement compiler integrations and code generation pipelines using Clang/LLVM
• Build reusable libraries, APIs, and toolchain components for developer consumption
• Integrate third-party frameworks and develop build automation systems
• Write comprehensive tests and establish quality assurance processes
• Optimize code for performance, reliability, and maintainability
• Collaborate with cross-functional teams including researchers and engineers
• Participate in code reviews, architectural discussions, and technical design
• Document technical decisions, APIs, and system architectures
• Stay current with C++ evolution and formal methods advancements
