PCB Designer – Coherent Optical Reference Boards
Irvine, CA
About the Role
- We are seeking an experienced PCB Designer to lead the development of high-performance reference and evaluation boards for next-generation coherent optical DSPs and modules (400G/800G/1.6T). These boards enable silicon validation, system bring‑up, and customer engagement.
- This role emphasizes power integrity (PI) and regulator design, while maintaining strong competency in signal integrity (SI) and awareness of mmWave RF line‑side routing (90 GHz+). The position also includes technical oversight of external contractors for schematic capture and PCB layout.
What you Will Do:
- Own end‑to‑end design of reference and validation boards for coherent optical DSP platforms.
- Define system architecture with strong focus on:
- Power tree design and sequencing.
- Robust PDN design for digital, analog, and RF domains.
- Design and optimize power delivery networks (PDN):
- Target impedance definition and verification.
- Plane design, stitching, and return path integrity.
- Select and implement DC-DC converters and LDOs:
- Efficiency vs noise trade‑offs.
- Load transient performance.
- Thermal considerations.
- Work with external contractors to execute:
- Schematic capture (including full power tree).
- PCB layout implementation.
- Review and enforce design quality for:
- SI constraints on high‑speed interfaces (90 GHz+).
- Collaborate with SI/PI engineers to validate PDN and channel performance.
- Incorporate debug and measurement features:
- Power rail probing, current sensing, and isolation points.
- High‑bandwidth measurement access for noise characterization.
- Drive schematics, layout, and DFM/DFA reviews and support tap out.
- Support bring‑up of boards and DSP.
What you Will Bring:
- Bachelor’s degree in Electrical Engineering or equivalent experience.
- 5+ years of PCB design experience with strong emphasis on power integrity and power design.
- Proven experience designing complex power trees for ASIC/DSP‑based systems.
- Strong experience reviewing and guiding third‑party schematic and layout work.
- Proficiency with PCB CAD tools (Cadence Allegro) and PI analysis tools (Sigrity).
- Deep understanding of:
- PDN design and target impedance concepts.
- Decoupling capacitor selection, placement, and optimization.
- Switching regulator design (buck converters, multiphase regulators).
- LDO design and noise‑sensitive supply generation.
- Solid understanding of:
- High‑speed SI fundamentals (differential routing, return paths, crosstalk).
- PCB materials and stack‑up trade‑offs.
- Experience with reference board design and silicon bring‑up.
Preferred Qualifications
- Experience with coherent optical systems or high‑performance DSP platforms.
- Experience correlating simulation with lab measurements (scope probing, VNA, TDR).
- Knowledge of:
- Power/ground plane resonance and damping techniques.
- Thermal considerations for high‑current regulators.
- RF‑aware layout practices for 90 GHz+ environments.
