Molex is seeking a very experienced Senior Principal Hardware Development Engineer to contribute to the design and development of advanced optical transceivers used in next-generation data center and telecom networks. This hands-on role requires deep technical expertise in optical transceiver architecture, component integration, and system-level performance, with a strong emphasis on innovation, reliability, and manufacturability. The successful candidate will play a pivotal role in our organization and will have the opportunity to work in a collaborative and innovative engineering environment.

• Provide critical contributions to the architecture, design, and validation of advanced optical transceiver modules (e.g., QSFP-DD, OSFP) supporting data rates of 800G, and higher.
• Responsible for the integration and bring-up of new optical transceiver designs.
• Collaborate with cross-functional teams including optics, mechanical, firmware, and system integration to ensure performance and compliance with industry standards.
• Define and drive transceiver-level characterization and validation.
• Act as a technical mentor and thought leader within the organization.
• Collaborate with customers and internal stakeholders to understand requirements and provide technical leadership.

• Bachelor’s degree in Electrical Engineering, Physics, or a related field; Master’s or PhD preferred.
• 10+ years of hands-on hardware design experience, with at least 5 years focused on coherent and/or PAM4 optical transceivers.
• Proficient in lab testing and characterization using OSA, BERT, OMA, eye diagram analysis, power meters, etc. Ability to automate measurements using C# or Python is an advantage.
• Familiarity with industry requirements such as IEEE and OIF.
• Excellent problem-solving, communication, and leadership skills.
