About the company

Our client is a software company.

The role

Raydar is recruiting for this role on behalf of our client. Work on performance-critical systems software written in C++, owning core library development and production troubleshooting. The role combines applied research, performance analysis and hands-on engineering in a fast-moving startup setting.

What you'll do

- Develop and maintain the core C++ library at the heart of a systems software platform.

- Research techniques for resource sharing, state snapshotting and high-performance GPU systems.

- Add support for new hardware architectures, drawing on a deep understanding of the full system.

- Debug systems-level issues in live production environments.

- Diagnose performance problems in customer workloads and trace them across the stack.

Requirements

What we're looking for

- Hands-on background shipping and supporting close-to-the-hardware software in live environments.

- Expert-level C++ skills; strong Rust experience may also be considered, though day-to-day work is in C++.

- Experience tuning network interface and C++ performance.

- Ability to follow performance problems through every layer of the stack.

- A strong academic record in computer science from a highly regarded university.

- A history of delivering quickly in an early-stage startup.

Bonus points

- Exposure to compilers, networking protocols or operating system kernels.

- Kubernetes or infrastructure experience, for example storage systems work or large-scale data ingestion.
