About This Job


Role Overview

As our Build Reliability Engineer, you’ll own the integrity of the production process from prototype to full-rate manufacturing. You will be the connective tissue between design, manufacturing, and quality—ensuring that our builds are repeatable, efficient, and reliable. You’ll play a critical role in developing robust manufacturing processes, executing quality assurance strategies, and continuously improving product reliability in a mission-critical environment.


Key Responsibilities:

Define and implement processes to ensure reliable hardware builds at scale
Participate directly in prototype and production builds to validate processes, tooling, and assembly instructions
Lead root cause analysis and corrective/preventive actions (RCAs and CAPAs) for production failures or field returns
Collaborate with design engineering to incorporate DFM/DFA best practices and ensure design-for-reliability


Manufacturing Engineering

Develop and optimize manufacturing workflows, tooling, and fixtures
Design custom fixtures and assembly aids to improve safety, efficiency, and consistency
Create build documentation including work instructions, travelers, and visual aids
Work hands-on with technicians, assemblers, and engineers on the floor to streamline builds and resolve issues in real-time
Partner with contract manufacturers and internal teams to scale production


Quality Engineering

Define quality control and inspection plans (IQC, IPQC, OQC)
Establish in-line and end-of-line test protocols to validate system performance
Implement and manage statistical process control (SPC) and process capability metrics
Maintain traceability and compliance with applicable quality standards and customer requirements


Who You Are

You thrive in ambiguity and enjoy solving hard problems with limited resources
You're equally comfortable on the manufacturing floor and in design review meetings
You believe quality and speed are not mutually exclusive
You take ownership and drive continuous improvement without waiting for permission


Qualifications

Bachelor's degree in Mechanical, Aerospace, Electrical, or Manufacturing Engineering (or similar technical field)
4–7 years of experience in manufacturing, quality, or reliability engineering—preferably in aerospace, defense, or high-reliability hardware environment
Proficient in 3D CAD design using SolidWorks, Creo, or similar tools—experience designing fixtures, tooling, and assembly aids is a strong plus
Hands-on experience with mechanical/electromechanical system builds and test setups
Solid understanding of DFM/DFA, root cause analysis, FMEA/PFMEA, SPC, and other reliability and quality methodologies
Familiarity with quality standards and systems such as AS9100, ISO 9001, or MIL-STD compliant
Comfortable working across ERP/MRP and PLM systems (e.g., NetSuite, Odoo, Arena)
Strong communication skills and a bias toward action—able to thrive in a fast-paced, build-focused environment
