Senior PCB Design Engineer

Role Overview

High-Speed PCB Layout

• Route 112G/224G SerDes, PCIe Gen 5/6, and DDR4/5/6 interfaces.
• Design differential pairs with tight skew and impedance control.
• Execute dense BGA fan-out for high-pin-count ASICs and FPGAs.

Optical Transceiver Layout

• Design boards supporting QSFP-DD, OSFP, OSFP-XD, or equivalent optical transceivers up to 800G and 1.6T.
• Route PAM4 channels and optimize breakouts beneath high-density optical cages.
• Manage return paths, EMI control, via stub mitigation, and thermal dissipation near optical connectors.

Signal and Power Integrity

• Design 20-to-30-plus-layer stack-ups and calculate impedance profiles for low-reflection and low-crosstalk performance.
• Collaborate on signal integrity channel modeling and pre-layout and post-layout simulations.
• Design PDNs and multiphase DC/DC layouts for high-current, high-transient ASIC loads.

Fabrication and Production

• Generate Gerber, ODB++, and IPC-2581 manufacturing packages.
• Define backdrilling parameters and impedance specifications and ensure DFM, DFA, and DFT compliance.
• Support boards through fabrication, assembly, and production ramp.

Library and Feasibility Ownership

• Create and maintain high-density component footprints for large BGAs and optical connectors.
• Participate in feasibility studies and develop routing guidelines for layout partners.
• Review external placement and routing work for quality and schedule adherence.

Qualifications

• Bachelor's or Master's degree in Electrical Engineering, Electronics, or a related field.
• At least 10 years of relevant hardware engineering experience.
• Experience with 100G/200G PAM4 Ethernet switching and 112G/224G routing.
• Advanced proficiency in Cadence Allegro and Sigrity.
• Experience with 20-plus-layer boards, sequential lamination, HDI, and ultra-low-loss materials.
• Experience with multiphase DC/DC layout and high-speed optical transceiver PCB layout.

Compensation

• Base pay is listed as a range of $133,000 to $180,000.
• Certain roles may also be eligible for discretionary bonuses and equity.
