## Description

Systems Technology, Inc. (STI) is seeking an Embedded Software Engineer - UAS to join our Aerospace division, supporting flight software development for next-generation UAS and counter-UAS platforms. You'll work at the intersection of guidance, navigation, and control (GNC) software and the embedded hardware it runs on - writing, testing, and debugging flight-critical code for fault-tolerant flight controllers and mission systems. This is hands-on work: you'll be as comfortable on an oscilloscope bench as you are in a debugger., * Design, implement, and test embedded C/C++ software for flight control and mission computer systems

 * Develop and debug low-level drivers and communication interfaces (CAN, SPI, I2C, UART, PWM) between flight controllers, sensors, and actuators
 * Support bring-up, integration, and troubleshooting of embedded hardware alongside electrical and mechanical engineers
 * Contribute to software architecture for fault-tolerant, dual-core flight control systems
 * Participate in flight testing, telemetry analysis, and post-flight debugging
 * Collaborate with GNC engineers to translate control algorithms into deployable flight code
 * Maintain code quality through version control, code review, and structured testing practices
