AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected.

We are seeking a Flight Software Engineer to develop, troubleshoot and maintain our Flight Software. The candidate will be one of the engineers responsible for developing new Flight Software, as well as providing Flight Software support for the Assembly, Integration, Test, Launch and Commissioning of our satellites. This will require the candidate to have an in-depth knowledge of not only the Flight Software, but also the system as a whole. The candidate will be an integral member of the Flight Software Team, responsible for developing and maintaining all Embedded Flight Software for AST. All Embedded Software development is done in C++ and can also involve hardware interaction for debugging and board bring-up activities.

Key Responsibilities:

Responsible for the design, development, and testing of new embedded software from initial concept to subsystem integration, through full system deployment.
Incorporate mission-specific microcontrollers into full systems capable of full spacecraft control.
Participate in design, code reviews and testing with the team.
Debug and troubleshoot embedded systems, including system bugs, hardware failures or combability issues.
Develop and test application-level software modules that utilize low-level peripheral drivers when applicable.
Document and communicate design decisions and progress.
Collaborate with other sub-system engineers to define and advance software specifications for development.

Technical Requirements:

At least 5-7 years of professional experience working with Embedded Programming

Ideally with experience in development and support

Familiar working with a Real-Time Operating System (RTOS)
Proficient with C and C++
- Comfortable with the C++ 11 (and beyond) standard library
Experience with multi-threaded environments
- Consideration for concurrency and inter-process communication
Familiarity with various protocols such as:
- Serial communication protocols (RS-232, RS-485, CAN, SPI, etc)
- Debugging interfaces (SWD, JTAG)
Comfortable with development tools/technologies such as:
- Oscilloscopes
- Logic analyzers
- Multimeters
Familiar with reading and analyzing circuit diagrams and schematics
