Lead High-Speed PCB Layout Engineer

Redwood City, CAOn-siteFull-time

AI Summary

Lead high-speed PCB layout engineer responsible for physical implementation of high-speed digital and mixed-signal electronics in Altium, including stack-ups, impedance targets, return-path strategy, and collaboration with design, firmware, mechanical, and test teams.

About this role

Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world.
We’re launching a coordinated fleet of radar satellites to create a high-resolution 3D map of the Earth – updated in real time – enabling faster, smarter decision-making for government and commercial organizations supporting disaster response, infrastructure resilience, and mission-critical geopolitical intelligence.
We design and build our satellites end-to-end, producing the world’s most advanced earth observation satellites. Our fleet will deliver unprecedented levels of accuracy, coverage, and responsiveness to power critical insights precisely where they’re needed most.
About the Job
As a Lead High-Speed PCB Layout Engineer, you will own the physical implementation of Array’s high-speed digital and mixed-signal electronics in Altium, translating schematics and performance requirements into layouts and functional designs. Your work will include component placement, constraint-driven routing, stack-up definition, return path and reference plane strategy, and partitioning between sensitive mixed-signal domains and high-speed digital interfaces.
You will partner closely with electrical design, firmware, mechanical, and test engineers to drive layout constraints, reviews, and manufacturing releases. The boards you ship will directly determine signal integrity, power integrity, noise performance, and overall system reliability in the lab and on orbit.

Responsibilities:

  • Own high-speed PCB layout from initial placement through manufacturing release in Altium
  • Define and implement stack-ups, impedance targets, length-matching constraints, and reference plane/return-path strategies for high-speed interfaces
  • Translate schematic intent into layouts that meet signal integrity and power integrity requirements across mixed-signal and digital domains
  • Partner with electrical design, firmware, mechanical, and test engineers to develop layout constraints, run reviews, and de-risk first-pass success
  • Drive DFM/DFT considerations with fabrication and assembly partners, including documentation and release artifacts

    • Basic Qualifications:

  • B.S. in Electrical Engineering, or a related field with 8+ years of relevant experience
  • Experience in PCB layout, fabrication, and release of high-speed digital and mixed-signal electronics
  • Excellent teamwork and communication skills
  • Learns new concepts rapidly, completely, and in a self-directed manner
  • High levels of self-motivation and personal accountability
  • Ability to work in a fast-paced environment under significant time constraints

    • Preferred Skills and Experience:

  • Experience designing high-speed digital and mixed-signal PCB layouts including constraint-driven routing, impedance control, and length matching
  • Comfort with Altium Designer for complex layout and clean manufacturing outputs; familiarity with Allegro and/or OrCAD
  • Experience developing PCB stack-ups and layout constraints for high-speed interfaces and dense, high-performance boards
  • A strong intuition for layout-driven SI/PI behavior, including return paths, reference plane strategy, via transitions, and noise coupling between domains
  • Experience working closely with electrical design engineers to translate schematic intent into layouts that work on the first spin
  • Experience with manufacturing release, DFM/DFT considerations, and collaborating with fabrication and assembly partners
  • Experience supporting lab bring-up and debug alongside design and test engineers, including investigating SI/PI issues observed on hardware
  • Familiarity with SI/PI analysis workflows and tools such as Ansys SIwave, Keysight Power Analyzer, HyperLynx, or Sigrity
  • Experience taking high-performance hardware from prototype through qualification and environmental testing

    • ITAR Requirements:

  • To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State
