Senior C++ Tooling Engineer

Description:

We need someone who deeply understands C++, compilers, and systems, but who builds the tooling in whatever language is fastest: Python, TypeScript, Rust, shell, glue code, prototypes. You'll be expected to identify what needs to exist, build it, and put it in front of users without a project manager holding your hand.

This role is unapologetically AI-native. We expect you to drive Claude Code, Codex, Cursor, or similar agentic coding tools as a core part of your workflow, not as a novelty, but as the way you ship.

Who Thrives Here

• People who treat a vague problem statement as a starting point, not a blocker
• People who default to action: build the prototype, run the experiment, ship the first version, then iterate
• People who hold a high bar for themselves without needing anyone to enforce it
• People who are energized by ambiguity and a fast cadence, not exhausted by them

We don't require prior Python or TypeScript experience. If you have strong C++ and systems judgment and you know how to drive a coding agent, you can produce tooling in whatever language the job needs. If you need fully-scoped tickets, weekly 1:1s to unblock you, or a stable roadmap that doesn't shift, this is not the right environment.

Requirements What you'll actually do

• Build developer tooling around a C++ codebase: code generators, AST analyzers, build orchestration, test harnesses, fuzzing infrastructure
• Work with Clang/LLVM where it matters (AST traversal, instrumentation, code generation), but reach for Python or TypeScript when that's the right tool
• Design property-based testing infrastructure and translate formal specifications into executable runtime checks
• Set up and tune fuzzing pipelines (libFuzzer, FuzzTest)
• Decide what to build, build it, ship it, learn from it, repeat
