Senior C++ Software Engineer — High-Performance R&D (Hybrid, Shannon)

Job Title

Senior C++ Software Engineer — High-Performance R&D (Hybrid, Shannon)

Role Summary

Join Siemens EDA's R&D team in Shannon to design and implement high-performance, production-grade components for next-generation electronic design automation (EDA) applications. The role focuses on performance, concurrency, distributed systems integration, and scalability for HPC-style workloads.

This is an engineering role on a hybrid team responsible for architecture, development, optimization, and mentoring within an Agile environment.

Experience Level

Senior — the role title indicates a senior-level position. The posting does not state a specific years-of-experience requirement.

Responsibilities

Primary technical responsibilities include building performant, reliable software and contributing to system architecture:

• Design, develop, and deliver production-ready components for high-performance EDA applications.
• Optimize code for multi-threaded, low-latency, and distributed execution environments.
• Contribute to architectural design for maintainable, extensible distributed systems and networking patterns.
• Integrate components across distributed systems using efficient inter-process and network communication.
• Implement and promote software quality practices: code review, unit/integration testing, and CI/CD automation.
• Diagnose and resolve complex performance, scalability, and stability issues.
• Provide technical leadership and mentorship to team members; collaborate with product and engineering teams to deliver features.

Requirements

Key must-have skills and desirable additions:

• Must-have: Strong mastery of modern C++ and C, with focus on performance optimization, memory management, and concurrency.
• Must-have: Experience developing in a Linux environment; fluency with Git and scripting for automation (Bash, Python).
• Must-have: Practical experience with multi-threaded programming, debugging low-latency systems, and software testing methodologies (unit/integration testing).
• Must-have: Solid core computer science fundamentals (data structures, algorithms, object-oriented design) and strong problem-solving skills.
• Must-have: Strong communication skills and ability to work in Agile, cross-functional teams; experience mentoring peers.
• Nice-to-have: Experience with distributed system communication frameworks (gRPC, MPI, message queues) and network programming (TCP/UDP, sockets).
• Nice-to-have: Containerization (Docker), orchestration, HPC/parallel computing experience, or familiarity with EDA/chip-design workflows.

Education Requirements

Bachelor's or higher degree in Computer Science, Engineering, Technology, or a closely related field (as stated in the posting).
