Embedded Simulation Engineer

At IBM Infrastructure & Technology, we design and operate the systems that keep the world running. From high-resiliency mainframes and hybrid cloud platforms to networking, automation, and site reliability. Our teams ensure the performance, security, and scalability that clients and industries depend on every day. Working in Infrastructure & Technology means tackling complex challenges with curiosity and collaboration. You'll work with diverse technologies and colleagues worldwide to deliver resilient, future-ready solutions that power innovation. With continuous learning, career growth, and a supportive culture, IBM provides the opportunities to build expertise and shape the infrastructure that drives progress.

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

As a Firmware Developer, you will design, develop, test, and deliver offerings for IBM Z using the latest technologies. You will work in a team-based, collaborative environment with peers both locally and across the global organization, applying agile methodologies throughout the entire development cycle. Your primary responsibilities will include: * Develop Firmware Components: Create and use design documentation, such as Functional Programming Specifications and high-level design documents, to implement identified components. Ensure that the implemented components are unit tested and ready to be integrated into the product. * Collaborate with Designers: Work with designers to understand users and create a tangible experience through combined efforts. * Debug and Test Code: Debug reported problems, design, develop, and unit test code fixes to ensure high-quality deliverables. * Deliver Solutions: Provide fixes for defects identified by customers and support the development of various projects, including hardware management console mobile apps and I/O adapters. * Apply Agile Methodologies: Participate in agile development cycles, including design, code implementation, review, unit testing, functional testing, simulation, and real hardware integration testing.

Your Role and Responsibilities

We are seeking a Full System Simulation Engineer with 4-6 years of experience in hardware-software co-development to build and maintain virtual platforms for SoC-level simulation on the IBM Z platform.

In this role, you will model hardware components, enable firmware bring-up, and integrate simulation environments into development and CI workflows-helping accelerate platform validation and software development ahead of physical hardware availability.

Core Responsibilities:

. Develop and maintain virtual platforms using simulation tools like QEMU and/or Simics

. Model hardware components such as:

o SoCs

o Peripherals (UART, I2C, SPI, etc.)

o I/O Subsystems

o Memory controllers

. Interpret and implement hardware specification documents into simulation models

. Enable full-system simulation, replicating real hardware behaviour

. Collaborate closely with firmware teams to support:

• • Boot flows
  • Driver development
  • System bring-up

. Integrate simulation into:

• • Test automation frameworks
  • CI/CD pipelines

. Debug system-level issues across:

• • Simulation
  • Firmware
  • OS layers
