Avionics Manufacturing Supervisor

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, ownership, and excellence are decisive advantages - and we're building a world-class team to turn bold ideas into real capability. 

This is a rare opportunity to join at an early stage, where you'll have significant ownership, collaborate with exceptional teammates, and make a direct, measurable impact on our mission and the future of the company - regardless of your function.  

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.

This role requires a strong technical and process-focused mindset combined with the people leadership and production ownership expected of a supervisor. 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.

This is not a purely administrative leadership position. The ideal candidate is excited to build and grow a high-performing team while remaining directly involved with hardware and complex technical challenges.

• Lead, develop, and provide daily direction to a team of Avionics Manufacturing Technicians

• Establish a scalable technician leadership structure and develop future technical leads

• Organize, prioritize, and assign work orders based on production needs, technician capabilities, hardware availability, and schedule requirements

• Monitor daily production execution, balance workloads, remove blockers, and ensure technicians are working safely and efficiently

• Maintain a strong presence on the manufacturing floor and provide hands-on support for complex builds, troubleshooting, PCBA rework, wire harnesses, integration, and test

• 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

• Ability to read electrical schematics, wiring diagrams, assembly drawings, and manufacturing documentation

• 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
