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.
