We are Firmware professional working on Z systems (modern mainframes) and we build the most secure systems for our customers to deploy their enterprise applications. Also, We provide at most security and enable IBM LinuxONE and z/OS enterprise customers with on-premise, customer-managed container solution through Secure Service Containers which provides data protection as well protection from Insider threats. We deliver Simulation and automation around platform management firmware to increase and deliver even higher quality and lay the foundation for future development work for Z systems
We are seeking a skilled and forward-thinking Embedded Simulation Engineer to join IBM ZFW team in building and evolving software-based hardware simulations for embedded systems development and testing.
This role is crucial for enabling early-stage firmware development and automated testing through virtual hardware models. You'll be working on simulation models that replicate real hardware—sometimes even before it exists. In the future, you will also help guide the evolution of the simulation toolchain itself.
Your Role & Responsibilities
- Design and implement device-level simulation models to replicate embedded hardware behaviour.
- Develop model logic and supporting tools using C, Python, XML, shell scripting, CMake and git.
- Enable simulation-based firmware development and automated CI testing.
- Collaborate with embedded software teams to ensure model accuracy and usability.
- Analyse the existing simulation stack and contribute to evaluating alternative platforms and tools for long-term needs.
- Gradually assume ownership of the team’s simulation mission as existing experts transition out of this area.
§ Proficient in DML (Device Modelling Language)
· Development and maintenance of device-level models using DML (Device Modelling Language)
· Modelling of hardware components such as SoCs, peripherals, memory controllers
· Deep integration with simulation environments to replicate embedded system behaviour
- Solid experience with embedded systems and device driver development (e.g., for U-Boot, Linux, or bare-metal).
- Proficient in Programming skills like – C, Python, XML, Bash, CMake, Git
- Ability to read and understand ARM32 and ARM64 assembly.
- Proficiency in C programming and scripting languages like Python and bash.
- Hands-on experience with simulation or virtualization environments for embedded systems.
- Independent working style and readiness to take over complex technical responsibilities.
- Strong communication skills in English (spoken and written).
- Experience with hardware simulation platforms such as Simics, QEMU or similar.
- Knowledge of device modelling languages (e.g., DML or equivalents).
- Basic understanding of system-on-chip (SoC) architecture and peripheral modelling.
- German language skills are a plus.
