Introduction
At IBM, work is more than a job - it's a calling: To build. To design. To code. To consult. To think along with clients and sell. To make markets. To invent. To collaborate. Not just to do something better, but to attempt things you've never thought possible. Are you ready to lead in this new era of technology and solve some of the world's most challenging problems? If so, lets talk.

Your Role and Responsibilities
We are Firmware professional working on Z systems ( IBM Advanced Mainframes ) and we build the most secure systems for our customers to deploy their enterprise applications. IBM z Systems are deployed with workloads where intensive IO Operations are getting executed. IBM Lab works on IO enablement firmware as well as boot firmware for z Servers. Work area would be Initial program load that is Boot firmware which enables the z Systems to boot and load supported Operating systems( Linux, zOS, zVM ) on Logical partitions.

Responsibilities:
As individual developer

• Design/Develop firmware which supports initial load program of z Systems and IO subsystem enablement for IO intensive workload running on zSystems.
• Design/Develop Initial load programme consists of IO configuration, Processor configuration and Memory configuration to suit the system to run various Operating systems.
• Design/Develop Storage and networking emulators/Test vehicles to verify and validate IO support protocols like Fibre channel protocol, FICON protocol.
• Design/Develop IBM proprietary protocols like zHyperlink - used to communicate to IBM Storage servers, Test Vehicle to emulate the Storage side of it.
• Design/Develop/Debug IO simulation environment used to design/develop IO firmware early in the program, which is Linux OS interacting with early hardware models, QEMU simulation models and Firmware code.

Required Technical and Professional Expertise
7-10 years of experience in
Must Have:

• Expertise in Firmware development, IO domain knowledge, Linux Systems programming knowledge, Use and debug code written in C on Linux environment. Basic knowledge in Object Oriented programming c++ language.
• Basic understanding about IO protocols like PCIe, I2C, SPI etc
• Good communication skills and be able to work effectively in a global team environment.
• Basic knowledge in Linux development environment GitHUB, CI/CD, Agile methodology
• Keywords: C programming AND System Software AND Linux Internals

Preferred Technical and Professional Expertise

• Z Systems experience, Prior experience / exposure to PCIe protocol, Assembly programming
