Staff Software Engineer – Compilers & Systems (LLVM / Toolchains)

Staff Software Engineer – Compilers & Systems (LLVM / Toolchains)

We are currently partnered with a hypergrowth startup ($150M in funding, scaling the team 5x this year) building AI that is transforming how Hard Tech innovation is designed, validated, and deployed. Backed by Tier 1 VCs and led by experienced founders and engineering leaders from some of the world’s top technology companies, this is an opportunity to join an elite team at a pivotal moment of scale.

They are seeking an experienced Compiler / Systems Engineer to play a key role in building next-generation tooling at the intersection of compilers, programming languages, and AI-assisted software development. You will work on deeply technical challenges, including compiler infrastructure, intermediate representations, and performance-critical systems that underpin advanced AI workflows.

Your work will involve designing and extending compiler toolchains, optimizing code generation, and integrating compiler-level intelligence into modern AI-driven development systems.

Required Skills & Experience:

• 4+ years of professional experience in Systems Engineering, Compilers, or Programming Languages
• Hands-on experience with LLVM (e.g. contributing to LLVM, building a compiler using LLVM, or working on IR/optimization passes)
• Strong understanding of compiler architecture (frontends, backends, optimization, codegen)
• Experience building or contributing to developer tools or systems software (e.g. package managers like Cargo, compression systems like Snappy, build systems, or similar low-level infrastructure)
• Proficiency in C++, Rust, or similarly low-level languages
• Strong fundamentals in data structures, algorithms, and performance optimization
• US Citizen or Green Card

This is a rare opportunity to work on deep systems problems that directly shape the future of AI-powered software development. You’ll own critical components of the stack, influence architectural decisions, and work directly with senior leadership.

You will be leading key technical initiatives and reporting directly to the SVP Engineering.
