## About the role

We are seeking a hands-on Senior PCB Layout Engineer to own the physical implementation of complex printed circuit boards used in characterization, validation, automated test equipment (ATE), production test, and internal engineering platforms. This role partners closely with hardware, signal integrity, mechanical, manufacturing, and test engineers to translate schematics and design constraints into robust, manufacturable PCB layouts. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 10+ years of hands-on PCB layout experience for complex, high-density electronic systems
- Expert-level capability in at least one major PCB layout platform, such as Cadence Allegro, Altium Designer, and working familiarity across common PCB design and review tools
- Demonstrated experience laying out multi-layer high-speed digital, mixed-signal, precision analog, RF, clock, and power designs
- Strong knowledge of PCB stack-ups, materials, controlled impedance, differential routing, length matching, crosstalk mitigation, return paths, grounding, and power integrity fundamentals
- Experience with fine-pitch BGAs, HDI, microvias, via-in-pad, blind/buried vias
- Practical knowledge of PCB fabrication, assembly processes, component land patterns, solder-mask and paste-mask design, panelization, tolerances, and manufacturing documentation
