About the role
Job Requirements Driver Development & Feature Engineering
• Design, implement, and optimize firmware-level device drivers for LPDDR5/6 DRAM controllers and associated memory subsystems; memory interconnects are proprietary to the platform — no prerequisite knowledge of specific interconnect protocols required. • Develop and enhance performance monitoring software to track memory controller metrics, bandwidth utilization, latency profiles, and hardware performance counters. • Develop and enhance drivers for memory-mapped I/O, DMA engines, cache controllers, and related peripherals. • Write clean, maintainable, and well-documented driver code in Python, C, and Rust (in order of priority). • Implement register-level programming from hardware specifications and datasheets. • Optimize driver performance for latency, throughput, and power across target SoC/FPGA platforms.
Integration & Bringup
• Integrate device drivers with firmware stacks, bootloaders, and RTOS/bare-metal environments. • Support hardware bringup activities; collaborate with hardware design and ASIC teams during bring-up phases. • Port or adapt drivers across different SoC platforms and board configurations.
Testing & Validation
• Design and execute comprehensive driver test plans covering functional correctness, stress, boundary conditions, and negative scenarios. • Develop Python-based test automation scripts and frameworks for driver validation. • Use hardware debug tools such as JTAG debuggers, logic analyzers, and oscilloscopes to validate signal integrity and protocol compliance. • Write unit tests and integration tests; contribute to CI/CD pipelines for firmware.
Root Cause Analysis & Debugging
• Independently investigate and resolve complex driver-level bugs including memory access faults, data corruption, race conditions, and timing violations. • Analyze memory dumps, trace logs, and register states to isolate root causes. • Document root-cause findings and corrective actions clearly for cross-functional teams.
Documentation & Collaboration
• Produce thorough design documents, driver interface specifications, and API documentation. • Read and interpret hardware datasheets, register maps, timing diagrams, and JEDEC LPDDR5/6 specifications independently. • Collaborate with hardware engineers, system architects, and firmware teams to define and refine driver requirements.
