ESSENTIAL DUTIES AND RESPONSIBILITIES

SSD firmware design and development in an agile environment, involving multiprocessor (ARM/ARC), multithreading, RTOS, with C/assemble programming, in interaction with various cross IP teams, with active participation on failure analysis and root causing. Participate in full life cycle of development, starting from requirements, high/low level design, implementation, unit testing, and support required documentation. Firmware development shall be on FPGA, real form factor, OR on a software simulated model environment. Developing firmware tests to exercise core firmware components such as file system, diagnostic framework, firmware update, boot process on the SSD controller before and after integration into product platform. Creating build scripts and using Python to build firmware for the enterprise SSD controller architecture. Testing firmware on HAPS (High-Performance ASIC Prototyping Systems) or in-house ASIC prototyping system emulating the SSD controller and exercising it on NAND and NOR flash memory by creating and/or executing system level tests using Python and in-house software tools Create unit tests to demonstrate code quality Providing guidance to test and/or Quality Assurance teams for system level product test execution. Debugging core firmware infrastructure issues coming from test as well as internal and external customers on the HAPS or inhouse ASIC prototyping system as well as product form factor using the Lauterbach TRACE32 debugger or debugger(s) developed internally at Western Digital. Designing and developing debug infrastructure for enabling quick diagnosis of failures in enterprise solid state drives. Designing and developing applications to collect and analyze diagnostic data, debug logs and event data from enterprise solid state drives. Self-motivated to work both unsupervised and as part of an agile team. Collaborate to develop self and others within group. Actively participate in innovation/trade secrete activities.
