PCB Librarian

Castelion Corporation•Torrance, CA

About The Position

As a PCB Librarian, you will own the management, curation, and quality of Castelion's PCB component libraries and associated design data. You will ensure that schematic symbols, footprints, and part metadata are accurate, compliant, and ready for integration into complex avionics systems. This role partners closely with PCB layout, electrical, and manufacturing teams to enable rapid, reliable, and high-quality hardware development across analog, digital, RF, and power domains. You will drive standardization, enforce best practices, and maintain library integrity, enabling engineering teams to efficiently deliver flight-ready PCBs on aggressive schedules. The position may require access to classified information or restricted U.S. Government sites, systems, or information, and requires access to export-controlled information. If applicable, employment may be contingent on obtaining and maintaining required government clearances or authorizations and satisfying relevant eligibility requirements.

Requirements

5+ years of experience in PCB design, component management, or electronics hardware development.
Strong proficiency in Altium or equivalent professional PCB design tools.
Experience managing component libraries, including symbols, footprints, 3D models, and metadata.
Solid understanding of high-density, multi-layer PCB design practices.
Familiarity with signal integrity, power distribution, grounding, EMI/EMC, and thermal considerations.
Knowledge of PCB fabrication, assembly processes, materials, and manufacturing constraints.
Experience supporting IPC Class 3/3A designs.
Strong attention to detail, problem-solving skills, and ownership mindset.
Ability to work effectively in cross-functional engineering teams and communicate across disciplines.
Ability to access applicable export-controlled information without additional export licensing being required.

Nice To Haves

Experience in aerospace, missile systems, spaceflight, defense, or other high-reliability environments.
Familiarity with boards containing microcontrollers, DSPs, FPGAs, ASICs, high-speed interfaces, RF/mixed-signal circuits, or power management.
Experience supporting EMI/EMC mitigation through library and layout techniques.
Knowledge of industry standards such as MIL-STD and DO-254.
Familiarity with signal and power integrity tools such as SiWave, HFSS, ADS, or CST.
Experience supporting hardware through environmental testing and qualification.
Ability to mentor engineers and elevate overall library and design quality.

Responsibilities

Own the creation, maintenance, and standardization of PCB component libraries, including symbols, footprints, 3D models, and metadata for avionics hardware.
Ensure libraries are accurate, manufacturable, and compliant with IPC Class 3/3A and Castelion internal standards.
Collaborate with PCB layout and electrical engineers to translate schematic intent into reliable, reusable library components.
Maintain and version-control library data, with appropriate documentation and traceability for production release.
Interface with vendors to confirm part specifications, availability, and manufacturability.
Review new component requests and validate footprints, 3D models, and pin assignments.
Support high-density, multi-layer PCB designs through accurate component representation and layout constraints.
Enable rapid iteration cycles by providing verified, production-ready library components for design re-spins.
Mentor junior engineers on library best practices, IPC standards, and DFM considerations.
Collaborate across electrical, mechanical, systems, and manufacturing teams to ensure library and design alignment.
Contribute to continuous improvement of Castelion's PCB library standards, processes, and tools.
