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.

- 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.
