Launcher Assembly Technician (m/f/d)

Mission Brief

As an Avionics Technician within the AIT team, you will play a critical role in the final assembly, integration, and checkout of our launch vehicle's avionic and electromechanical systems. You will be responsible for routing and installing complex wire harnesses, integrating precision sensors and avionics units, and supporting critical test operations. This role requires a high degree of craftsmanship, working with both advanced composite and metallic structures, and operating safely around high-pressure and cryogenic fluid systems.

Your Role in Our Space Mission:

Key Responsibilities

• Harness Routing & Installation: Route, secure, and install complex vehicle wire harnesses in accordance with engineering drawings and aerospace standards.

• Structural Bonding & Adhesives: Prepare surfaces and bond ClickBond clips and standoffs to metallic and composite structures. Apply aerospace-grade adhesives.

• Avionics Unit Installation: Install and mechanically secure telemetry modules, batteries, and other avionics enclosures.

• Precision Mechanical Assembly: Use torque wrenches and calibrated hand tools to mate structural and electrical components, ensuring strict adherence to torque specifications and engineering drawings.

• Crimping & Soldering: Perform high-reliability crimping, pinning, and soldering on flight connectors and wire splices.

• Rework & Modification: Execute precise rework and modifications on existing wire harnesses, connectors, and pinouts based on engineering change orders.

• Sensor Installation & Checkout: Install and connect critical flight sensors (pressure transducers, thermocouples, RTDs, accelerometers, etc.) and verify functionality.

• Fluid Connections: Install fluid lines using Swagelok fittings and components for instrumentation and purging systems.

• Hazardous Operations Support: Work in close proximity to or directly interface avionics components with Cryogenic Liquid Oxygen (LOX) and Liquid Propellant (LPP) systems, adhering to strict cleanliness (oxygen clean) and safety protocols.

• Electrical Checkouts: Utilize multimeters, megohmmeters, and specialized test equipment to perform continuity, isolation, and bonding checks.

• Testing & Troubleshooting: Conducting integrated system testing and pre-launch checkouts alone or alongside test engineers
