• Own PCB hardware development from concept through release, including architecture, design, and validation.
• Work closely with internal PCB designers during layout to ensure design intent is accurately implemented.
• Provide layout guidance and conduct detailed PCB design reviews, with particular focus on high-speed interfaces.
• Ensure proper routing of high-speed RF and digital interfaces to meet bandwidth, loss, and crosstalk requirements.
• Validate thermal, power, and signal integrity considerations in collaboration with cross-functional teams.
• Partner with firmware, mechanical, manufacturing, and test teams throughout the development lifecycle.
• Participate in formal design reviews and engineering evaluations, presenting design rationale and analysis results.
• Support troubleshooting and validation activities at both board and system level, including root-cause analysis.
• Provide technical expertise and leadership across the hardware development process from concept to product release.
• Perform analysis and validation of hardware designs using appropriate tools and methodologies.
• Support simulation and modeling activities, including SPICE and CST simulations, to predict and optimize performance.
• Troubleshoot board-level and system-level issues and drive corrective actions to closure.
• Ensure products meet customer specifications, performance requirements, and reliability targets.
• Contribute to design verification and simulation strategies for high-speed RF and digital hardware.

• At least 5 years of hardware design experience in board-level electronics development.
• Proven experience leading board-level hardware development efforts from architecture through release.
• Strong digital circuit design experience, including high-speed digital design.
• Strong analog circuit design experience for complex board-level systems.
• Demonstrated ability to develop schematics from scratch using professional EDA tools such as PADS.
• Experience selecting and evaluating electronic components for high-performance applications.

• Ability to read and interpret complex component datasheets and translate them into robust design implementations.
• Knowledge of high-speed digital design principles and practices.
• Understanding of RF fundamentals relevant to high-speed communication systems.
• Strong grasp of signal integrity concepts and their application in PCB design.
• Strong grasp of power integrity concepts for reliable high-speed hardware.
• Experience with board-level architecture development for complex electronic systems.
• Industry experience in telecommunications hardware, optical networking, fiber optics, optical communications, high-speed communications systems, or networking infrastructure.

• Experience with optical transceiver design and development for advanced networking platforms.
• Experience with DCO modules or similar optical communication modules.
• Background working with DSP-based communication systems and their hardware interfaces.
• Experience supporting optical products and solutions for high-speed communications.
• High-speed RF design experience, including designs that consider bandwidths exceeding 100 GHz.
• Hands-on experience with CST simulation software for electromagnetic and RF analysis.
• Proficiency with PADS schematic capture tools for professional hardware design.
• Experience with SPICE simulation for circuit analysis and verification.
• Experience integrating optical components into board-level designs.
• Exposure to telecom hardware deployed in hyperscale environments.
• Experience working with 1.2T and 1.6T class networking products and related hardware platforms.
• Design verification and simulation experience across digital, analog, RF, and power domains.

This role offers remote flexibility with a strong preference for working onsite approximately three days per week in a collaborative engineering environment. You will partner closely with multidisciplinary teams including RF, firmware, mechanical, PCB layout, manufacturing, and test engineering, using professional EDA tools such as PADS, SPICE, and CST for design, simulation, and verification. The work focuses on advanced optical transceiver and high-speed networking hardware, with an emphasis on rigorous design reviews, performance validation, and cross-functional collaboration.
