Your Job
Molex is seeking a Senior PCB Layout Engineer to join our Optical Solutions Business Unit (OSBU). In this role, the successful candidate will be part of a world-class engineering team, contributing to the design and development of next-generation coherent and PAM4 optical transceivers. The Senior PCB Layout Engineer will be responsible for creating high-speed, high-density PCB layouts that meet stringent signal integrity, power integrity, and thermal requirements. This role involves close collaboration with electrical, mechanical, optics and process integration engineers across global teams to ensure optimal performance, manufacturability, and reliability of our advanced optical transceiver modules.
Our Team
R&D Optoelectronic Solutions
What You Will Do
- Lead multi-layer PCB layout design for high-speed optical transceivers (e.g., QSFP-DD, OSFP).
- Translate complex schematics into production-ready layouts using EDA tools.
- Define layout constraints, stack-ups, and component placement in collaboration with cross-functional teams.
- Support board bring-up and debug through layout reviews, lab measurements, and issue resolution.
- Ensure compliance with DFM, DFT, and IPC standards; coordinate with vendors to address fab and assembly issues.
- Generate and manage all fabrication and assembly outputs (Gerbers, ODB++, BOMs, drawings).
- Mentor junior engineers and drive continuous improvement in layout processes and design practices.
Who You Are (Basic Qualifications)
- Bachelors degree in Electrical Engineering, Electronics Engineering, or a related field.
- More than 8 years of hands-on PCB layout experience in high-speed digital or optical communication products.
- Proficient in Allegro PCB design software.
- Strong knowledge of high-speed signal integrity, power integrity, PCB stack-up design, and layout best practices.
- Experience with interfaces such as SerDes (e.g., 112G/224G PAM4), IC, SPI, MDIO, and power delivery networks.
- Familiarity with EMI/EMC mitigation techniques and thermal design considerations.
- Solid understanding of PCB fabrication and assembly processes.
What Will Put You Ahead
- Experience with 800G & 1.6T optical transceiver PCB layout.
- Familiarity with signal and power integrity simulation tools (e.g., Sigrity, Ansys, HyperLynx).
- Previous involvement in volume production and high-reliability designs for data center or telecom applications.
