Job summary

Castelion is seeking a seasoned PCB Layout Engineer to own flight-critical avionics PCBs from layout to release. You will partner with electrical, mechanical, systems and manufacturing teams to implement robust, manufacturable designs for hypersonic systems, ensuring IPC Class 3/3A compliance and tight schedules.

You will drive placement, routing, stack-up decisions, and vendor interactions, contributing to design standards, and mentoring junior designers in a fast-paced, highly collaborative

Qualifications

• 5–8+ years of PCB layout and electronics hardware development.
• Proficiency with Altium (preferred) or equivalent.
• Experience taking complex PCBs from concept through production release.
• Experience designing high-density, multi-layer PCBs (10–20+ layers).
• Solid understanding of signal integrity, power distribution, grounding, EMI/EMC, and thermal considerations.
• Experience designing to IPC Class 3 / 3A requirements.
• Knowledge of PCB fabrication processes, materials, stack-ups, and manufacturing constraints.
• Experience working directly with PCB fabrication and assembly vendors.

Responsibilities

• Own PCB layout from initial placement through fabrication and assembly release for complex avionics hardware.
• Translate schematic intent and system requirements into robust, manufacturable PCB layouts.
• Drive component placement, stack-up definition, routing strategy, and constraint management across analog, digital, RF, and power domains.
• Lead PCB DFM/DFA reviews with fabrication and assembly vendors; close manufacturing issues through release.
• Develop and maintain PCB fabrication and assembly packages (Gerber/ODB++, BOMs, drawings).
• Interface directly with board houses to select materials, stack-ups, impedance targets, and DFX rules.
• Ensure designs meet IPC Class 3/3A and Castelion internal design standards.
• Maintain and expand the PCB component library; contribute to company-wide layout standards and best practices.
• Support signal integrity, power integrity, and EMI-focused layout trade studies.
• Collaborate with electrical, mechanical, systems, and software engineers through integration, test, and qualification.
• Support rapid iteration cycles and hardware re-spins in a fast-paced development environment.
• Provide technical guidance to junior PCB designers and review peer layouts.
• Communicate clearly across disciplines and sites to keep hardware on schedule.
