Integration Engineer

Heart Aerospace is an electric aviation company focused on electrifying regional air travel through the development of battery-electric aircraft. The company is designing the ES-30, a 30-seat electric regional aircraft intended to serve short-haul routes with zero CO2 emissions, offering airlines a fundamentally lower-cost operating model compared to conventional turboprop or jet aircraft. Heart Aerospace also operates the X1 experimental aircraft as part of its development program to validate core technologies ahead of the ES-30's entry into service. The company's mission is centered on decarbonizing aviation, starting with regional routes where electric propulsion is most technically and economically viable. By targeting short-distance air travel, Heart Aerospace aims to eliminate direct carbon emissions on these segments while making regional connectivity more affordable for both operators and passengers. The company has secured investment from leading venture capital firms aligned with electrification and decarbonization goals, as well as strategic investments from major airlines that have also signed on as early customers. Heart Aerospace was founded in Sweden and has established a presence in the United States, with its listed address in Torrance, California. The company represents a new generation of aerospace manufacturers betting that advances in battery technology and electric drivetrains can transform commercial aviation, beginning with the regional segment where routes are short enough to make today's battery energy density practical.

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
