Simulation Engineer
New college grad software engineer building and improving functional and pipeline-accurate simulators in C++ for Cerebras' wafer-scale AI engine. Requires strong C++ and computer architecture knowledge to support hardware/software co-development across kernel, compiler, and verification teams.
About the job
Responsibilities
- Develop and maintain simulator infrastructure in C++ for next-generation WSE systems.
- Contribute to both functional simulation (architectural correctness, instruction behavior, and state and memory semantics) and pipeline-accurate simulation (execution behavior, bottleneck analysis, and performance visibility).
- Build features and tooling that improve kernel developer visibility into correctness and performance.
- Work with Design Verification and architecture teams to align simulator behavior with hardware specifications and validate design correctness.
- Build and maintain strong unit, integration, and regression test coverage for simulator quality.
- Improve simulator runtime performance, scalability, and usability for internal engineering workflows.
- Debug complex issues that span simulator models, kernels, compiler/runtime interactions, and hardware assumptions.
- Contribute to code reviews, documentation, and continuous improvement of engineering workflows.
Skills & Qualifications
- Bachelor's or Master's degree (or equivalent) in Computer Science, Computer Engineering, or a related field.
- Strong C++ programming skills and software engineering fundamentals.
- Solid understanding of computer architecture concepts, including instruction execution, memory systems, and microarchitecture basics.
- Strong debugging, analytical, and problem-solving skills.
- Ability to collaborate effectively across software and hardware teams.
Preferred Skills & Qualifications
- Familiarity with architectural, functional, or performance modeling.
- Experience with test automation, regression systems, and CI pipelines.
- Exposure to Python or scripting for tooling and automation.
- Familiarity with parallel systems, accelerators, or ML/HPC workloads.
