PCB Librarian

Requirements

• Own the creation, maintenance, and standardization of PCB component libraries (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, ensuring proper 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.
• 5+ years of experience in PCB design, component management, or electronics hardware development.
• Strong proficiency in Altium (preferred) 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.
• 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 (e.g., MIL-STD, DO-254).
• Familiarity with signal and power integrity tools (e.g., SiWave, HFSS, ADS, CST).
• Experience supporting hardware through environmental testing and qualification.
• Ability to mentor engineers and elevate overall library and design quality.
• Willingness to support extended hours or weekend work during critical integration, test, and flight milestones.
• Bias to Action and Creative Problem Solving.
• High Commitment, High Initiative.
• Clear Communicator.
• ITAR Requirements: To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
