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.Our headquarters is based in Gothenburg, Sweden and we are now opening up a R&amp;D hub in Los Angeles, which will focus on the advancement of Heart’s hybrid-electric propulsion system and other key technologies.Your missionAs a Staff Software Engineer, Battery Systems, you are responsible for all aspects of development for software relating to the battery systems, including interfacing with engineers to develop and understand requirements, modeling the battery system, architecting and writing high quality code, building tests and test infrastructure, documentation, and supporting through the software lifecycle. You will report to the Manager of Flight Software and work very closely with the Battery Team as part of a multi-functional team. As an early hire within the organization, part of your responsibility will be to lay the technological foundation for the battery control scheme, including but not limited to writing analytical battery models, developing the control architecture and writing real-time and embedded controls algorithms. Key responsibilities include but are not limited to:<ul><li>Lead the development and prototype the Battery Management system that includes controllers and firmware to deliver the most power and energy possible while maximizing capacity retention over the life of Battery Packs. </li><li>Lead the deployment of algorithms, firmware, and hardware that predict available power and energy, functions that ensure optimal charging, effective thermal management, and high-voltage safety monitoring while ensuring warranty and lifetime.</li><li>Design models, define algorithms, write testing code, and evaluate the performance throughout the lifetime of the product.</li><li>Deliver State-of-Charge, State-of-Health, State-of-Power, and State-of-Energy computations and estimations.</li></ul>You will initially report to the Director of Battery and belong to the Battery team. Your place of work will be at our office located in El Segundo, CA (Los Angeles). You'll Bring These Qualifications:<ul><li>8+years of professional experience in software development, with a significant focus on battery controls and embedded systems.</li><li>Deep understanding of battery technology, particularly lithium-ion cells, and BMS principles. These include cell balancing, thermal management, state-of-charge/state-of-health estimation, and fault detection. </li><li>Experience writing software in Rust, Python, C or C++. </li></ul>These Qualifications Would Be Nice to Have:<ul><li>Experience developing analytical models of battery systems.</li><li>Experience writing code for execution in an embedded environment (microcontrollers, bare metal, RTOS, embedded OS). </li><li>Experience developing software under a functional safety compliant process (for example, compliant to IEC 61508, ISO 26262, DO-178C, or similar). Strong understanding of functional safety and how to apply it to software development. </li><li>Experience with software and hardware test development. Experience with unit tests, CI/CD, integration testing, data collection and management, report generation, fuzzing and other advanced automated test methods. </li><li>Experience with high-voltage battery systems.</li><li>Experience with communication protocols commonly used in embedded systems (e.g., CAN, SPI, I2C, Ethernet). </li><li>Passion for electric aviation and sustainable technologies. </li></ul>Education<ul><li>Bachelor’s or above in electrical engineering, computer science, or similar engineering discipline. </li></ul>

Heart’s mission is to create the fastest, most affordable and sustainable transportation for regional travel to every corner of the world. Their first aircraft is the ES-19, a nineteen-passenger airliner with an operating range of 400 km. Heart's goal is to have the aircraft certified for commercial operation by 2025.
