NUVACORE builds for the stratosphere. Maximum performance. Absolute area efficiency. No compromise. A general-purpose CPU core designed to excel everywhere, from core infrastructure to advanced AI systems, including the continuous demands of agentic computing. Backed by Sequoia.
About the role
As a Compiler & Toolchain Engineer, you'll be a core member of the team building and maintaining Nuvacore's compiler and toolchain stack across GCC and LLVM along with core libraries and runtime environments. You'll work close to the metal — implementing machine models for our microarchitecture, chasing down codegen correctness and performance issues, and partnering directly with CPU architects to extract every bit of performance possible. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- 15+ years of professional experience working on compiler internals — frontend, middle-end, or backend — in LLVM and/or GCC
- Strong understanding of compiler backend construction: instruction selection, register allocation, instruction scheduling, and code generation
- Low-level programming experience targeting x86, ARM, or RISC-V architectures
- Proven experience debugging functional and performance issues in large, complex software systems
- Experience working within modern, automated software development methodologies (CI/CD, automated testing, code review tooling)
- Strong written and verbal communication skills
More about this role
At NUVACORE we're designing a new general-purpose CPU core for the sustained, intensive demands of AI infrastructure and agentic computing, not the workloads of the past. Our software organization works at the intersection of CPU architecture, silicon design, firmware, operating systems, toolchains, and platform software — developing the compiler toolchains, OS enablement, firmware, and validation infrastructure that ensure new processor capabilities are fully realized in software. We're hiring a Compiler & Toolchain Engineer to accelerate and harden the toolchains and libraries that help unlock the performance of Nuvacore's processors.
