General Summary

As a Qualcomm USB Platform Customer Engineer, you will provide technical expertise and customer-facing engineering support for the design, integration, validation, optimization, and commercialization of Qualcomm-based products. You will work closely with OEM/ODM partners and global Qualcomm teams to resolve complex USB, system software, hardware integration, and platform-level issues across Linux, Android, Windows, and UEFI environments.

The role focuses on USB feature enablement, system integration, performance tuning, interoperability, stability analysis, certification support, and issue resolution throughout the product development lifecycle.

This position requires close collaboration with OEM/ODM customers and Qualcomm teams across multiple regions. Flexibility may be required to support customer milestones, cross-region debug activities, issue escalations, and product commercialization schedules.

Responsibilities

Customer Platform Support

• Work directly with OEM/ODM customers on the design, integration, validation, optimization, testing, and commercialization of Qualcomm 5G, AR/VR, IoT, edge AI, and computing products.

• Provide technical guidance for USB and peripheral integration across hardware, firmware, operating-system, and application layers.

• Reproduce customer issues, identify root causes, recommend solutions, and drive issues to closure across regions and time zones.

USB Integration, Validation, and Certification

• Support USB host, device, and dual-role functionality, including USB2, USB3, USB4, and USB Type-C.

• Validate interoperability across operating systems, firmware configurations, cables, hubs, docks, repeaters, storage devices, cameras, and other peripherals.

• Investigate enumeration, connect/disconnect, suspend/resume, reset, power-management, compatibility, and certification issues.

Software, Firmware, PHY, and Performance Debugging

• Support USB driver development, integration, and debugging on Linux, Android, and Windows across user space, kernel space, firmware, UEFI, and bootloader environments.

• Debug driver failures, system hangs, crashes, kernel stability issues, and unexpected USB behavior using JTAG, GDB, logs, crash dumps, tracing tools, and platform diagnostics.

• Support USB2/USB3 PHY tuning, link validation, electrical compliance, throughput characterization, and system performance optimization.

• Use LeCroy or equivalent protocol analyzers to investigate transactions, link behavior, protocol errors, packet failures, and reduced throughput.

Platform Issue Resolution and Collaboration

• Analyze interactions among USB, PCIe, I2C, SPI, UART, memory, storage, clocks, regulators, PMICs, thermal policies, and system power states.

• Correlate logs, traces, protocol captures, hardware measurements, and test results to isolate root causes and develop validated patches or workarounds.

• Prepare technical reports, debug plans, presentations, validation plans, and commercialization-readiness updates for customers and internal stakeholders.

• Collaborate with platform, silicon, hardware, BIOS/UEFI, firmware, driver, OS, validation, and test teams to deliver timely resolutions.

Qualifications

• Bachelor's degree in Engineering, Information Systems, Computer Science, or a related field; a Master's degree is a plus.

• 3+ years of experience in software, embedded systems, platform integration, validation, or customer engineering, preferably in the wireless, telecommunications, semiconductor, or computing industry.

• Proficiency in one or more programming or scripting languages, such as C, C++, Java, Python, PyTorch, or similar; strong C/C++ and embedded-programming skills are preferred.

• Experience developing or debugging Linux/Android software in user space and/or kernel space, with system-level debugging using JTAG, GDB, logs, tracing tools, or crash-analysis utilities.

• Strong analytical, problem-solving, communication, and customer-facing skills, with the ability to manage multiple priorities and work effectively with global teams.
