Lead Engineer, USB

Role Overview

• Own USB enablement on Linux
• driver bring-up, compliance, and AVV from FPGA to first silicon.
• USB Linux enablement & integration: enable and maintain USB host/device/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), PHY integration, clocks/resets, and interrupts.
• Drive kernel/BSP enablement: Device Tree bindings, power management (runtime/PM QoS), suspend/resume, and performance tuning.
• Develop/debug USB drivers and related subsystems: 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: integration, regression validation, and developer-facing documentation/debug guides.
• AVV & silicon validation (pre/post-silicon): 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/FPGA; build reusable USB validation apps/tests to exercise 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); drive fixes to closure.
• Cross-functional ownership: 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 & 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.
• Customer & ecosystem engagement: support early adopters and upstream fixes when appropriate (kernel, Device Tree, test collateral).

Requirements

• B.E./B.Tech or M.E./M.Tech in Computer Engineering, Electrical Engineering, or a related field.
• Strong experience with minimum 8-15 years 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 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 tools; able to debug complex HW/SW interactions.
• Experience working on FPGA, emulation, or early-silicon platforms for bring-up/validation.

Tech Stack

• Linux

Benefits

• Build a RISC‑V MPU platform from the ground up and see it shipped in real products.
• End-to-end ownership across pre-silicon → FPGA → first silicon → production SDK releases.
• Work closely with CPU architects and SoC teams, your data drives decisions.
• Deep technical work, strong peer group, and long-term growth on a strategic platform.
