Electrical Engineer

Why Castelion, Why Now

Castelion is moving incredibly fast to develop and deliver advanced defense systems at a time when execution matters more than ever. We believe focus and technical excellence are decisive advantages - and we are building a team that can deliver real capability, not just concepts.

This is a rare opportunity to join at an early stage, where your work will directly shape critical systems, influence major technical decisions, and have immediate, real-world impact.

Electrical Engineer

As an Electrical Engineer, you will become the Responsible Engineer for multiple mission-critical circuit card assemblies (CCAs) that power Castelion's flight systems. While the initial designs have been completed, you'll take ownership of the products through qualification, production readiness, and full-rate manufacturing.

This is an exceptional opportunity for an early-career engineer to gain end-to-end product ownership at a rapidly growing aerospace company. You'll work closely with experienced electrical, manufacturing, quality, and supply chain engineers to transition complex electronics from prototype to production while ensuring reliability, manufacturability, and long-term support.

At Castelion, engineers own their hardware throughout its entire lifecycle—from design refinement and qualification through production, field support, and continuous improvement.

Responsibilities

• Serve as the Responsible Engineer for multiple circuit card assemblies (CCAs) supporting flight hardware.
• Drive electronic hardware through design verification, qualification, and production readiness.
• Support environmental, electrical, and functional qualification testing and document test results.
• Partner with Quality Engineering to establish production metrics, acceptance criteria, and manufacturing quality processes.
• Support the transition of electronic hardware into Low Rate Initial Production (LRIP) and Full Rate Production (FRP).
• Investigate and resolve manufacturing, production, and supplier issues to ensure uninterrupted hardware delivery.
• Collaborate with component manufacturers and suppliers to address obsolescence, availability, and technical challenges.
• Update schematics and documentation to improve manufacturability, reliability, and component availability.
• Review PCB layouts and schematic designs to ensure compliance with design intent and manufacturing best practices.
• Support root cause investigations, corrective actions, and continuous improvement initiatives.
• Work cross-functionally with electrical, manufacturing, quality, supply chain, and integration teams throughout the product lifecycle.
• Contribute to process improvements that increase product quality, production efficiency, and hardware reliability.

Basic Qualifications

• Bachelor's degree in Electrical Engineering or a related engineering discipline.
• Ability to read and interpret electrical schematics and PCB layout files.
• Experience modifying schematics using Altium Designer or similar ECAD tools.
• Understanding of printed circuit board (PCB) and circuit card assembly (CCA) manufacturing processes.
• Familiarity with electronic components, power distribution, signal integrity, and circuit design fundamentals.
• Strong analytical and troubleshooting skills.
• Excellent communication and collaboration skills in a multidisciplinary engineering environment.

Preferred Skills and Experience

• Experience with Cadence Allegro or other PCB design toolsets.
• Familiarity with IPC standards for PCB and electronics manufacturing.
• Experience supporting design verification, qualification, or environmental testing.
• Experience working with manufacturing, quality, or supplier engineering teams.
• Python programming experience for automation, testing, or data analysis.
• Experience in aerospace, defense, automotive, robotics, or other hardware development environments.
• Familiarity with configuration management and engineering change processes.
