Job Description:

Join the winning team! Lattice is looking for a motivated and experienced Staff Design Engineer to integrate and productize USB IP and subsystems for next-generation FPGA products. The role focuses on USB 2.0 and USB 3.x controller and PHY integration, spanning subsystem validation, software enablement, silicon bring-up, and collaboration across Design, DV, Software, Applications, and external IP partners.

• Own the integration of USB controller and USB PHY IP into the FPGA subsystem, including digital interfaces, configuration paths, clock/reset connectivity, and integration requirements.
• Define and implement the subsystem-level RTL, wrappers, adapters, control logic, and configuration interfaces required to integrate USB controller and PHY IP.
• Work with Design Verification teams to define integration test plans and validate end-to-end USB subsystem behavior through simulation, emulation, FPGA prototyping, coverage closure, and pre-silicon debug.
• Drive subsystem-level root-cause analysis across USB controller-to-PHY interaction, integration RTL, software or firmware configuration, interoperability, compliance, and silicon behavior.
• Work with software and firmware teams to define and validate USB configuration, feature enablement, diagnostics, enumeration, initialization, and user-flow requirements.
• Integrate and review DFT and DFD requirements for the USB subsystem, including testability, debug observability, silicon bring-up, and production-test considerations.
• Work with third-party suppliers of USB controller and PHY IP to clarify interface and configuration requirements, review deliverables, and resolve integration, verification, and silicon issues.
• Develop and maintain USB subsystem integration specifications, interface requirements, configuration documentation, and bring-up guidelines. 
• Support integrated USB subsystem bring-up, laboratory debug, protocol analysis, compliance and interoperability testing, and customer issue resolution; document findings and drive assigned issues to closure.
• Identify engineering activities that can benefit from AI assistance, and propose, develop, and deploy practical AI-assisted workflows for design, verification, debug, data analysis, and technical documentation.
• Participate in design reviews and quality checks, and contribute to continuous improvement of design and debug methodologies.

• Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, Computer Engineering, or a related discipline.
• Typically 8+ years of semiconductor, ASIC, SoC, or FPGA design experience.
• Strong RTL design and subsystem integration experience, including clock/reset architecture, configuration interfaces, timing, and CDC/RDC considerations.
• Strong experience with USB 2.0 or USB 3.x controller, protocol, subsystem integration, or related USB PHY technology.
• Experience working with Design Verification teams and debugging pre-silicon design or integration issues using simulation, emulation, or FPGA prototyping environments.
• Experience supporting silicon bring-up, laboratory debug, interoperability, or customer issue resolution.
• Experience working with DFT or DFD methodologies, including testability, debug observability, scan/ATPG, silicon bring-up, or production-test considerations.
• Demonstrated experience identifying opportunities, proposing, developing, and implementing AI-assisted engineering workflows to improve design and integration productivity, technical investigation, debug, data analysis, and documentation.
• Strong technical communication and collaboration skills across engineering disciplines.

• Experience with USB protocol operation and debug, including enumeration, link state transitions, power management, error recovery, and compliance or interoperability testing.
• Experience with USB controller-to-PHY interfaces and specifications, such as UTMI/UTMI+, ULPI, PIPE, or related integration interfaces. 
• Experience with SerDes-based protocols or high-speed serial interfaces, including protocol architecture, controller-to-PHY integration, link bring-up, or system-level debug.
• Understanding of USB PHY and mixed-signal behavior, including clocking, calibration, termination, equalization, jitter, reset sequencing, power management, initialization, and bring-up. Direct analog circuit design experience is not required.
• Experience integrating third-party USB controller or PHY IP and working with external IP suppliers on requirements, deliverables, integration, verification, or silicon issues.
• Familiarity with physical-design interfaces such as synthesis, LEC, static timing analysis, or timing closure.
• Experience with design-quality methodologies such as Lint, CDC, RDC, low-power/UPF, or related structural checks.
• Knowledge of firmware, device configuration, APIs, scripts, drivers, or FPGA software-tool enablement.
• Exposure to USB compliance, interoperability, package, board, signal-integrity, connector, or platform-level considerations.
