We are looking for experienced C++ software engineers who thrive on "impossible" scaling challenges and want to invent the algorithms that will power tomorrow’s silicon.
Responsibilities:
- Enhance and support Xcelium RTL/logic simulator engine to add new features and extend existing features.
- Enhance and support Timing Constraints Verification technology used inside Xcelium simulator.
- The role involves designing, tuning, and innovating graph algorithms involving SDC constraints support on multi‑billion‑node graphs.
- Conduct deep-dive bottleneck analysis and implement performance optimizations in C/C++ to improve compilation speed and memory footprint.
- Lead junior engineers and collaborate with global team members to deliver high-quality results in a distributed environment.
- Contribute to technical discussions, code reviews, and process improvements.
- Write Specifications and Unit Tests for your code.
Position Requirements/Qualifications:
- MS in Computer Science or Electrical Engineering with a minimum of 12 years of experience OR PhD with a minimum of 10 years of experience
- 10+ years of experience in EDA software development.
- Strong background in RTL/Logic Simulation, SDC constraints and Timing Analysis especially path exceptions handling in a STA tool.
- Excellent programming skills in C/C++ and a deep understanding of SystemVerilog or Verilog.
- Experience in multi-threaded/ concurrent programming.
- Ability to quickly learn new technologies and adapt to project requirements.
- Prior experience with RTL/logic simulation software development is an added plus.
