You'll Bring These Qualifications as a Senior Software Engineer: * Bachelor's or above in computer science, electrical engineering, or similar engineering discipline. * 5+ years professional experience writing safety-critical code for vehicles, or similar applications. * Excellent verbal and written communication skills in English. * Passion for aircraft and Heart’s mission. You'll Bring These Qualifications as a Staff Software Engineer:  * 8+ years professional experience writing safety-critical code for vehicles, or similar applications. * Excellent verbal and written communication skills in English. The ideal candidate would have: * Significant experience writing software in Rust, Python, C, C++, or a similar systems language. * Experience writing code for execution in an embedded environment (microcontrollers, bare metal, RTOS, embedded OS). * Experience modeling cyber-physical systems (6 DoF Simulators, Monte Carlos, Battery Pack Models). * Strong systems design fundamentals. Experience architecting software systems (and contributing requirements to hardware design) for vehicle systems. Experience with various approaches to fault tolerance and fault mitigation. * Significant 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. * 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. Base Pay Range: * Senior Software Engineer: $155,000 —$193,000 USD. * Staff Software Engineer: $190,000 —$238,000 USD.

PRINCIPAL ELECTRICAL ENGINEER (HARDWARE DESIGN) Freeform builds AI-native manufacturing systems that unify software, hardware, and physics to produce industrial-scale parts at the speed of human ideation.
