USB Lead Engineer

Overview

Own USB enablement on Linux for a 64-bit RISC-V MPU SoC platform, covering driver bring-up, compliance, and automated validation (AVV) from FPGA through to first silicon.

What you'll do

• Enable and maintain USB host, device and dual-role functionality on a 64-bit RISC-V MPU Linux platform.
• Bring up USB controllers (e.g., xHCI/EHCI for host, UDC for device/gadget), including PHY integration, clocks/resets and interrupts.
• Drive kernel/BSP enablement: Device Tree bindings, power management (runtime/PM QoS), suspend/resume and performance tuning.
• Develop and debug USB drivers and related subsystems, including USB core interactions, hub behavior, gadget framework and class drivers as needed.
• Enable and validate user-space workflows: enumeration, throughput/latency, storage/networking classes, and reliability over hot-plug scenarios.
• Deliver USB-ready SDK releases with integration, regression validation, and developer-facing documentation/debug guides.
• Create test plans and automation to validate USB functionality, performance and compliance on FPGA/emulation and first silicon.
• Contribute to shift-left validation using virtual platforms, emulation or FPGA, and build reusable USB validation apps/tests exercising data paths and corner cases.
• Debug and root-cause USB issues across HW/FW/kernel using logs, traces and lab equipment (e.g., JTAG, logic/protocol analyzers), and drive fixes to closure.
• Partner with architects, RTL/PHY, board and platform teams to define requirements, de-risk schedules and land USB features.
• Own USB feature planning: role/port matrix, power and charging considerations, compliance goals and bring-up milestones.
• Provide bring-up and validation feedback that influences USB architecture decisions (controller/PHY selection, debug hooks, observability, testability).
• Align with internal and external stakeholders on deliverables, bug triage and release readiness for USB enablement.
• Support early adopters and upstream fixes when appropriate (kernel, Device Tree, test collateral), and work with OEMs/Tier-1s during bring-up and USB interoperability.

What you'll need

• B.E./B.Tech or M.E./M.Tech in Computer Engineering, Electrical Engineering, or a related field.
• Minimum 8-15 years of experience in Embedded Linux platform/BSP and device-driver development.
• Expert-level C programming; comfortable reading and modifying kernel, driver and low-level firmware code.
• Strong Linux internals knowledge: boot flow, memory/interrupt subsystems, concurrency and performance debugging.
• Hands-on SoC/platform bring-up experience, including high-speed I/O enablement and an ownership mindset for subsystem quality.
• Hands-on with U-Boot, Linux kernel, Device Tree and Yocto/OpenEmbedded; experience integrating and validating USB in BSP/SDK releases.
• Strong debugging skills with GDB and at least one OpenOCD/JTAG, Lauterbach or similar tool; able to debug complex HW/SW interactions.
• Experience working on FPGA, emulation or early-silicon platforms for bring-up/validation.

Nice to have

• Deep USB knowledge (USB2/USB3) and familiarity with Linux USB architecture (usbcore, HCD, gadget framework).
• Experience with USB compliance/interoperability testing and post-silicon triage (throughput, link stability, suspend/resume, hot-plug).
• Exposure to USB Type-C/PD, retimers, and/or Alt Modes (e.g., DisplayPort).
• Familiarity with platform security boundaries relevant to USB (secure boot, firmware/OS boundaries, attack surface considerations).
• Experience with QEMU, virtual platforms or emulation workflows used for early driver/test development.
• Exposure to CI/CD and automated validation (Python/shell test frameworks, dashboards, regressions) for continuous USB quality.
