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
