Firmware Developer

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 developerDesign/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.
