Siemens Digital Industries Software is a global leader in Electronic Design Automation (EDA) software, hardware, and design solutions. We partner with the world’s leading producers of semiconductor microelectronic circuits and systems, enabling them to design and produce cutting-edge electronic products faster and more efficiently. We are seeking a Software Development Engineer to join our SLS team in Cairo, Egypt . Responsibilities: Develop high-performance, functional models for hardware IPs such as processors, caches, memories, peripheral devices, and interconnects. Develop and integrate Instruction Set Architecture (ISA) simulators for various architectures (e.g., Arm, RISC-V, TriCore, PowerPC). Implement model functionality using C/C++ , SystemC , and Transaction-Level Modeling (TLM) . Develop and utilize open-source Instruction Set Simulators (e.g., QEMU ) within a virtual prototyping environment. Contribute to complex software development and ongoing maintenance activities. Participate in design, specification, and code reviews to ensure high quality and consistency. Analyze and profile complex software to drive continuous performance improvements. Create implementation and test plans and execute them according to defined schedules. Apply unit and integration testing for CPU, peripheral device, and interconnect models against behavioral models. Configure, build, and debug complex software stacks, including operating systems (Linux, RTOS) and bare-metal applications, to enable bring-up on CPU models and virtual platforms. Simulate and debug customer software as well as virtual platform models. Write clear functional specifications and design/test documentation. Qualifications: B.Sc. or M.Sc. in Electronics, Communications, or Computer Engineering; fresh graduates or experienced candidates in a relevant domain can apply. Strong programming experience in C/C++ , with solid knowledge of algorithms, data structures, OOP concepts, SOLID principles, and design patterns. Strong understanding of computer architecture and microarchitecture , including familiarity with microprocessor/microcontroller design, digital and logic design concepts. Experience in software development, analysis, debugging, tracing, and troubleshooting of complex systems. Familiarity with SystemC/TLM modeling and Instruction Set Simulators (e.g., QEMU ) is preferred; exposure to virtual platforms is a plus.! Experience with Linux system programming, multi-threading , and embedded software environments ( Linux/RTOS , bare-metal) is a plus. Programming experience with Shell scripting, Python, Tcl, or Perl , along with strong knowledge of Unix/Linux operating system environments. Strong problem-solving abilities and excellent communication skills, including the ability to clearly present ideas and share knowledge with others. We’re Siemens.
