About The Position

Castelion is hiring a PCB Layout Engineer to independently own the layout and release of complex avionics printed circuit boards for hypersonic missile systems. The engineer will partner with electrical, mechanical, systems, and manufacturing engineers to deliver flight-worthy hardware on aggressive schedules. The role requires sound technical judgment across analog, digital, RF, and power domains, and the ability to guide fabrication and assembly partners through design-for-manufacturing reviews and production readiness. The engineer is expected to work with minimal oversight and contribute to improving PCB design standards and processes. The position supports rapid hardware iteration, integration, testing, and qualification. Access to export-controlled information is required. Depending on the role designation, access to classified information or restricted U.S. Government sites, systems, or information may also require a security clearance or other government authorization and applicable eligibility requirements.

Requirements

5–8+ years of experience in PCB layout and electronics hardware development.
Strong proficiency with Altium or equivalent professional PCB layout tools.
Experience using mechanical CAD tools such as NX or SolidWorks for ECAD–MCAD coordination.
Proven experience taking complex PCBs from concept through production release.
Experience designing high-density, multi-layer PCBs, typically 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.
Strong problem-solving skills, attention to detail, and an ownership mindset.
Ability to operate effectively in highly cross-functional engineering teams.
Ability to access applicable export-controlled information without additional export licensing being required.
If designated for the position, ability to obtain and maintain required U.S. Government security clearance or other government authorization and meet applicable citizenship or other eligibility requirements.

Nice To Haves

Experience in aerospace, missile systems, spaceflight, defense, or other high-reliability hardware environments.
Hands-on experience with boards containing microcontrollers, DSPs, FPGAs, or ASICs.
Experience with high-speed digital interfaces such as DDR3/4, SerDes, and ADCs/DACs.
Experience with power management and sensor interfaces.
Experience with RF and mixed-signal circuitry.
Familiarity with signal and power integrity tools such as SiWave, HFSS, ADS, or CST.
Experience supporting EMI/EMC mitigation through layout techniques.
Familiarity with relevant industry standards such as MIL-STD and DO-254.
Experience supporting hardware through environmental testing and qualification.
Ability to mentor junior engineers and elevate team layout quality.

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 and resolve manufacturing issues through release.
Develop and maintain PCB fabrication and assembly packages, including Gerber/ODB++, BOMs, and drawings.
Work 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 and 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 across disciplines and sites to help keep hardware on schedule.
Support extended hours or weekend work during critical integration, test, and flight milestones.
