Senior/Staff Software Engineer, Flight Software

Los Angeles, CA

At Heart Aerospace we are developing 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

As a Senior/Staff Software Engineer on the Flight Software Team, you are responsible for all aspects the development of the software on the aircraft. You will interface with other engineers to develop and understand requirements, architect and writing high quality code, build tests and test infrastructure, documentation, and provide support through the software lifecycle. Part of your responsibility will be to lay the technological foundation for the aircraft software and supporting systems, including but not limited to implementing aircraft control functions on embedded systems, developing aircraft models and simulation tools, implementing critical fault tolerance mechanisms, and building hardware and software test systems. You will report to the Manager of Flight Software and collaborate with other engineers as part of a multi-functional team.

Key Responsibilities include but are not limited to:

• Lead design and implementation of complex embedded software systems.
• Architect fault-tolerant, safety-critical software solutions.
• Writing production-quality and developing code in systems languages such as Rust, C, C++, or Python.
