## About the Role

* Bachelor of Science degree in Engineering or another STEM field and a minimum of 5 years of experience as a Quality Engineer in a fast-paced manufacturing environment.
 * Extensive experience interfacing with design engineering, manufacturing, production, integration, and test personnel.
 * In-depth knowledge of electrical and avionics manufacturing, wiring harness assemblies, electrical system integration, and associated quality processes and controls.
 * Working knowledge of typical PLM, MES, ERP, and QMS software and proficiency with engineering drawings, electrical schematics, and wiring diagrams.
 * Ability to solve complex technical problems, evaluate alternative solutions, and coordinate across multiple teams to establish goals and drive projects to completion.
 * Strong communication and presentation skills, with demonstrated experience developing processes, driving first-time quality, and collaborating with technical teams and leadership.

Nice to haves but not required:

 * Working knowledge of product development methodologies such as Failure Modes and Effects Analysis (FMEA), Advanced Product Quality Planning (APQP), Statistical Process Control (SPC), and Production Process Verification (PPV).
 * Experience with new product introduction (NPI), particularly integrating electrical and avionics systems into manufacturing, assembly, test, and production environments.
 * Familiarity with aerospace electrical systems, including wiring harness fabrication, connector assembly, soldering, crimping, continuity testing, and electrical inspection methods.
 * Understanding of AS9100/ISO9001 applications and practices for an aerospace program, as well as IPC/WHMA-A-620 and IPC J-STD-001 standards.
 * Self-starter who has demonstrated the ability to define, own, and implement processes from scratch while effectively communicating across diverse teams.

## Description

* Support design activities including drawing standardization, design for manufacturability (DFM), configuration management, and electrical system requirements to ensure avionics hardware quality throughout production and integration.
 * Review work instructions, develop processes, and establish standard rework and repair documentation to support efficient and reliable avionics manufacturing, assembly, and installation.
 * Oversee in-process build verification, electrical inspections, wiring harness fabrication and installation, and coordination of traveled work to ensure quality standards are maintained throughout production.
 * Manage nonconformance processes, as-built verification, root cause investigations, and corrective actions to resolve electrical manufacturing and avionics integration issues while minimizing impacts to production schedules.
 * Drive initiatives to improve quality across avionics manufacturing and integration, including developing specifications, establishing inspection plans, improving electrical verification methods, and supporting inspection and test automation.
 * Develop strong working relationships with Engineering, Manufacturing, Avionics, Integration, and Test teams to identify risks, resolve technical challenges, and ensure successful electrical system assembly and integration.
