CodSpeed is a software performance optimization tool that allows engineering teams to optimize and measure code performance before it is deployed to production or shipped anywhere. Thanks to this approach, we avoid regressions that impact user experience and help developers solve their performance issues faster. CodSpeed is already trusted as the go-to solution for performance optimizations by top-tier open-source project teams such as Pydantic, Ruff, and Prisma.
We’re at an exciting early stage and looking for talented engineers who share our passion for helping to enhance the performance of software used by billions of people, improving the software development lifecycle, and building tools we love to use ourselves.
What you’ll do
- Build the next generation of high-performance CPU simulation tooling to improve how we measure performance
- Work with high-level language interpreter codebases (CPython, V8, …) to enhance our instrumentation quality
- Build various kernel’s I/O emulations to provide robust performance metrics agnostically from the hardware
- Be a founding engineer - you’ll make core architecture choices, ship significant features to production, and shape the company culture
Requirements
- Experience in a System Programming language: C, C++, Zig or Rust
- Understanding of Unix systems and kernels
- Deeply care about technical excellence
Extras
- Deep understanding of modern CPU Architectures
- Experience with Javascript and Python runtime internals and optimization pipelines
- Experience with GPU(CUDA) programming
- Experience leading significant projects in startup environments
