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   Offices: Los Angeles, California, United States (Torrance);
