• Optimize and simplify the usability, configuration, and diagnostics of distributed simulation, targeting performance improvements for critical customer use cases.
• Develop and integrate Multi-Core Checkers to accelerate simulation by distributing checker modules across processor cores while ensuring simulation accuracy.
• Work on performance improvements, bug fixes, and usability enhancements related to Xcelium's multi-core technologies including RTL acceleration.
• Translate high-priority customer requirements into scalable and robust technical solutions applicable to a broad user base.
• Collaborate closely with product engineering, field applications, and R&D teams worldwide to troubleshoot issues, define solutions, and facilitate customer adoption.
• Analyze and address performance bottlenecks affecting runtime, scalability, and resource use in distributed and multi-core simulation workflows.
• Enhance user experience through better error reporting, sensible defaults, automation, and documentation-friendly practices.
• Write high-quality, maintainable code with strong emphasis on correctness, diagnostics, regression testing, and long-term supportability.
• Investigate and resolve complex functional, performance, and field issues related to Xcelium multi-core technologies.
• Define test coverage and regression strategies in cooperation with product validation teams.
• Engage in global cross-functional collaboration to align architectural and implementation strategies across multi-core projects.
• Lead significant software feature areas end-to-end from design through implementation and maintenance.
• Contribute to technical documentation and promote internal knowledge sharing and best practices.
• Stay abreast of advancements in verification workloads, SoC simulation needs, and high-performance simulation technology trends.
• Manage and prioritize tasks through Agile methodologies, facilitating sprint planning, progress monitoring, risk identification, and removal of blockers to improve team delivery efficiency.

Required Qualifications and Skills

• Bachelor’s degree in Computer Science or a closely related technical field.
• Minimum 5 years of hands-on software development in complex C/C++ environments, preferably within EDA, simulation, compiler technology, runtime systems, or HPC.
• In-depth knowledge of multi-threaded, multi-process, and distributed software architecture focusing on synchronization, communication, debugging, and performance optimization.
• Proven track record developing performance-critical infrastructure prioritizing scalability, correctness, and reliability.
• Experience with Linux environments, debugging tools, version control systems, build automation, and regression testing methodologies.
• Familiarity with SystemVerilog, Verilog, UVM, logic simulation, or semiconductor verification is highly advantageous.
• Background in EDA simulation tools, distributed and multi-threaded systems, and inter-process communication is a plus.
• Strong analytical skills with the capability to debug complex issues in large-scale codebases and customer deployments.
• Excellent English communication skills for global collaboration with engineering and customer support teams.
• Self-driven, detail-focused, and capable of independently managing challenging technical assignments from concept through to production support.
