Senior PCB Layout Engineer, High-Density Robotics

Triwill Group; San Francisco, Northern (CA, KY); Hybrid; USD 120,000 - 190,000; Full time

Job summary

OpenAI is seeking a PCB Layout Engineer in San Francisco to design high-density electronics for next-generation robotic systems. You will own the PCB layout from floor planning through fabrication release, collaborating with electrical, SI/PI, mechanical, and manufacturing teams.

The role requires 6+ years of experience with complex multilayer PCBs, Cadence Allegro, and HDI design, including fine-pitch BGAs and via-in-pad. In-person presence four days a week is expected.

Qualifications

• 6+ years of experience designing complex, multilayer PCBs.
• Are fluent in Cadence Allegro PCB Designer and Constraint Manager.
• HDI design experience, including fine-pitch BGAs, microvias, blind and buried vias, via-in-pad, and sequential lamination.
• Understand signal and power integrity fundamentals, including return paths, differential pairs, length matching, crosstalk, and power delivery.
• Have experience working with PCB fabricators on stack-up development, manufacturing constraints, and DFM.
• Communicate effectively across engineering disciplines and with external manufacturing partners.

Responsibilities

• Own PCB layout, component placement, routing, and fabrication release for complex robotic systems.
• Collaborate with SI/PI engineers to refine layouts based on simulation results.
• Implement high-speed routing, controlled impedance, power distribution, decoupling, grounding, EMI/EMC, thermal, and mechanical-integration requirements.
• Work directly with fabricators and assembly partners to define stack-ups, establish design rules, drive DFM/DFA/DFT reviews, and close findings before release.
• Prepare fabrication and assembly documentation, including drawings, ODB++, drill files, stack-up tables, and manufacturing notes.
• Inspect newly received PCBAs and participate in board-level manufacturing failure analysis.
• Contribute to reusable design constraints and layout workflows, and maintain component-library assets such as symbols, footprints, and 3D models.
