Electrical 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 are developing the ES-30, a regional hybrid-electric airplane capable of carrying 30 passengers, boasting an electric zero-emission range of 200 km and an extended hybrid range of 800 km. Heart is targeting type certification of the ES-30 by the end of the decade.

As we transition from prototype to production, we are expanding our in-house electronics capability to deliver flight-worthy actuators, controls, and monitoring systems that match the ambition of our aircraft.

Your mission

We are seeking a Electrical Engineer who excels in owning the full printed-circuit-board assembly (PCBA) lifecycle—from concept and schematic capture through layout, verification, and manufacturing release. In this role, you will design multiple boards in parallel, coordinate build schedules, and work closely with software and mechanical teams to deliver tightly integrated subsystems for flight-critical applications. 

Key responsibilities include but are not limited to:

• Architect & design PCBAs for high-reliability, mixed-signal, and power-conversion applications (up to 900 V DC and high-speed digital buses).
• Own schematic capture, component selection, and constraint-driven layout using Altium Designer (or similar), while enforcing design rules for signal integrity, thermal management, and manufacturability.
• Perform design reviews, simulations, and worst-case circuit analyses (SI/PI, DFMEA, thermal, EMC) to meet DO-160, DO-254, and RTCA environmental standards.
• Lead bring-up and validation testing, authoring test plans and writing Python/Rust/C test scripts in collaboration with software engineers.
• Collaborate daily with mechanical engineers to optimize board outlines & connectors.
• Drive continuous improvement in Heart’s electronics development workflow—automating checks, tightening version control, and mentoring junior engineers.

You'll Bring These Qualifications:

• 3+ years of professional experience in PCBA design and NPI for safety-critical or aerospace products.
• Proven ownership of at least one product from concept to volume production
• Proficiency in ECAD tools (Altium or equivalent)
• Expertise in high-speed communication (Ethernet), power electronics (up to kW-level), and embedded-system interfaces (CAN, ARINC-429, Ethernet, SPI/I²C).
• Hands-on experience with lab instrumentation (oscilloscopes, VNAs, thermal chambers) and debugging of EMI/EMC issues.

These Qualifications Would Be Nice to Have:

• Experience certifying electronics for Part 23/25 aircraft or eVTOL platforms.
• Working knowledge of design assurance processes (DO-160, DO-254, IPC-2221/2222, IPC-7351).
• Knowledge of motor-drive control or battery-management circuitry.

Education

• Bachelor’s or master's in electrical engineering (or equivalent).
