Core Responsibilities

Primary Functions

Lead the complete electrical hardware design lifecycle, from initial requirements gathering and architectural definition through to detailed design, validation, and release to manufacturing.
Create, review, and maintain detailed electrical schematics, ensuring designs are robust, manufacturable, and meet all performance specifications.
Develop complex multi-layer printed circuit board (PCB) layouts, managing component placement, routing constraints, and signal integrity for high-speed digital and sensitive analog circuits.
Perform detailed circuit analysis, simulation (e.g., SPICE, HyperLynx), and tolerance analysis to guarantee design performance and reliability under all operating conditions.
Select, qualify, and manage the lifecycle of critical electronic components, including creating and managing comprehensive Bills of Materials (BOMs).
Design and implement robust power distribution networks (PDNs), including power conversion, regulation, and management for complex systems.
Develop and execute comprehensive Design Verification Test (DVT) plans to validate hardware functionality, performance, and robustness against system requirements.
Troubleshoot, debug, and perform root cause failure analysis on complex electronic systems and sub-assemblies during development and post-launch.
Ensure all designs adhere to relevant industry standards and regulatory requirements, such as FCC, CE, UL, and RoHS compliance.
Interface directly with PCB fabrication and contract manufacturing partners to oversee the build process, providing DFM/DFA feedback and resolving technical issues.
Author and maintain detailed engineering documentation, including design specifications, test procedures, technical reports, and errata sheets.
Conduct signal integrity (SI) and power integrity (PI) analysis to ensure reliable performance of high-speed interfaces like DDR, PCIe, and Ethernet.
Design analog and mixed-signal circuits for applications such as sensor interfaces, data acquisition, audio processing, and power management.
Participate in and lead formal peer design reviews, presenting technical concepts and implementation details to a cross-functional engineering team.
Develop and validate test fixtures and automated test scripts to support both engineering validation and high-volume production testing.
Collaborate closely with mechanical engineering teams on system packaging, thermal management, and electromechanical integration.
Work with firmware and software teams to define hardware/software interfaces, support board bring-up, and debug system-level issues.
Conduct feasibility studies and trade-off analyses on new technologies, components, and design methodologies to drive innovation.
Manage prototype builds, coordinating with vendors and internal teams to ensure timely delivery and successful bring-up of new hardware.
Provide expert-level technical support to sustaining engineering and customer support teams for fielded products.

Secondary Functions

Support manufacturing and quality teams by providing technical guidance to resolve production line issues and improve yields.
Contribute to the development and continuous improvement of the organization's electrical design best practices, tools, and processes.
