Avionics Manufacturing Supervisor

Why Castelion, Why Now

Castelion is bringing a new approach to defense development and production: one that focuses on short, iterative design cycles, rapid testing in development, and modern commercial manufacturing strategies for production at scale. We're designing, building, and testing next generation long range strike weapons systems to give America and its Allies a definitive edge and deter future conflicts.

Avionics Manufacturing Supervisor

Castelion is looking for an Avionics Manufacturing Supervisor, reporting to the Lead Manufacturing Engineer of Avionics, to support the development and production of systems required for long-range hypersonic strike vehicles. This will be a full-time position located at our Torrance, California facility.

As an Avionics Manufacturing Supervisor, you will lead and develop a team of Avionics Manufacturing Technicians while owning daily production execution across PCBA rework, wire harness manufacturing, electro-mechanical assembly, integration, and test.

You will organize and assign work, monitor execution, develop technicians, resolve production issues, identify opportunities for improvement, and maintain a strong hands-on presence on the production floor.

• Identify and raise concerns involving hardware, drawings, work instructions, tooling, materials, quality, manufacturability, or schedule

• Coordinate with Manufacturing Engineering, Avionics Engineering, Quality, Planning, and Supply Chain to resolve production issues

• Coach technicians, identify training needs, and expand team capabilities across avionics manufacturing processes

• Drive improvements in productivity, first-pass yield, repeatability, workmanship, and production flow

• Support the development and improvement of manufacturing tooling, fixtures, work instructions, test equipment, and processes

• Ensure work orders, inspection records, test results, nonconformance documentation, and manufacturing records are completed accurately and on time

• Support the transition of avionics hardware from development builds into repeatable production

• Experience leading technicians, assigning work, and supporting daily production execution

• Hands-on experience building, testing, troubleshooting, or repairing avionics or electrical hardware

• Experience with PCBA rework, wire harness manufacturing, electro-mechanical assembly, or electrical test

• Working knowledge of IPC-A-610, IPC/WHMA-A-620, or similar workmanship standards

• Proficiency with electrical test equipment such as multimeters and oscilloscopes

• Strong communication, organization, and technical problem-solving skill

Basic Qualifications

• 5+ years of avionics, electronics, electrical manufacturing, or related production experience

Preferred Skills and Experience

• Experience supervising technicians in aerospace, defense, electronics, automotive, or another high-reliability manufacturing environment

• Experience building, testing, or repairing flight hardware

• Experience managing work orders, labor assignments, production schedules, and daily output

• Advanced PCBA rework, wire harness manufacturing, or electrical troubleshooting experience

• Experience improving tooling, work instructions, test equipment, manufacturing processes, or production metrics
