About the role
Key responsibilities & impact- Make independent technical contributions to help their team deliver its commitments.
- Optimize AI, HPC, and other workloads and benchmarks for our RISC-V silicon with vector extensions.
- Identify bottlenecks with workload characterization and drive implementation of solutions.
- Decompose applications and how they run on the underlying hardware.
- Understand performance at a system level, from CPU, memory, storage, power utilization, etc.
- Profile and optimize on our pre-silicon (simulators, emulators, FPGAS), and silicon environments.
- Troubleshoot and root cause analysis, to resolve performance issues.
- Optimize HPC and AI libraries and runtimes.
- Work with customers to optimize their important workloads for our architecture.
- Contribute to instrumentation of performance and power at the operating system level.
- Integrate with CI/CD to automate performance benchmarking.
- Present findings to senior technical leaders at our company and at industry conferences.
- Contribute upstream where appropriate.
- Interact with colleagues across projects to unblock issues, or to reach consensus on technical topics.
- Work with hardware teams, influencing hardware/software co-design.
- Work with teams developing compilers, firmware, AI stacks, middleware, etc., and contribute as necessary.
- Collaborate with colleagues through code reviews, bug triaging, design documents,...
- Contribute to shared team responsibilities (CI failure triaging, documentation, code fixits, rotations...).
Requirements
What you’ll need- Bachelor or Master’s degree in a relevant field.
