Integration Engineer

At Heart Aerospace we develop the ES-30, a regional hybrid-electric airplane with a capacity of 30 passengers, an electric zero-emission range of 200 km and an extended hybrid range of 400 km. Heart is targeting type certification of the ES-30 by the end of the decade.

Your mission

We are looking for a highly motivated, hands-on Integration Engineer to lead the mechanical and electrical integration of critical subsystems across our hybrid-electric aircraft platform. You will be responsible for bridging design, manufacturing, final assembly, and testing to ensure that complex systems come together seamlessly from prototype through rate production. 

This is a cross-disciplinary role at the heart of aircraft development, where attention to detail, fast-paced execution, and strong problem-solving instincts are key. You’ll work side-by-side with design engineers, manufacturing, and technicians on the production floor to turn ambitious designs into high-performance, certifiable products. 

Key responsibilities include but are not limited to: 

 System Integration & Assembly 

• Own the integration of propulsion, battery, avionics, and structural systems into the aircraft platform
• Define and document build sequences, mechanical interfaces, fastener strategies, cable routing, and fluid line installations
• Support and optimize aircraft-level assembly processes, from first article to full-rate production

Design Collaboration & DFM 

• Provide real-time design-for-assembly feedback to design engineering teams 
• Influence interface definitions, mounting strategies, and accessibility for maintainability 
• Drive resolution of interface issues between subsystems during development and build 

Build Floor & Hands-On Support 

• Act as the technical liaison on the build floor to troubleshoot integration issues and lead root cause investigations 
• Support technicians during assembly with guidance, documentation, and process improvements 
• Ensure that integration work meets engineering intent, quality standards, and certification requirements 

Process Development & Continuous Improvement 

• Create and maintain detailed work instructions, assembly drawings, and configuration documentation 
• Work with manufacturing and engineering teams to improve efficiency, reduce errors, and streamline assembly processes 
• Support integration testing and data collection during system bring-up and aircraft checkout 

Your place of work will be at our office located in Torrance, CA. Some domestic travel may be required

 Skills & Requirements 

• Bachelor’s degree in Mechanical, Aerospace, or Systems Engineering (or equivalent experience) 
• 2+ years of experience in aerospace, automotive, or advanced manufacturing environments 
• Strong understanding of mechanical systems, fasteners, electrical connectors, harnessing, and fluid systems 
• Proficiency in CAD (e.g., NX, CATIA, or SolidWorks) and interpreting engineering drawings with GD&T 

 These Qualifications Would Be Nice To Have

• Experience in aircraft or vehicle final assembly, particularly with electrical and fluid system integration 
• Exposure to configuration control, hardware traceability, and change management 
• Demonstrated ability to work cross-functionally in high-speed development programs 
• Experience with electric propulsion, high-voltage systems, or thermal integration
• Comfortable working hands-on with tools and hardware in a production environment 

Base Pay Range:  $124,000—$176,000 USD
