Embedded Software Engineer - UAS (Aerospace Division)

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

• 3–5 years of professional software development experience
• Proficiency in C and/or C++
• Strong problem-solving, analysis, and debugging skills
• U.S. Person status required, as defined by ITAR (22 CFR 120.15), due to the export-controlled nature of this work
• This is an on-site position based in Hawthorne / Los Angeles, CA; remote or hybrid work is not available

• Experience with UAS, UAVs, drones, or RC aircraft
• Experience developing software for embedded systems or microcontrollers
• Familiarity with embedded communication protocols such as CAN, SPI, I2C, UART, or PWM
• Familiarity with Git and modern software development practices
• Familiarity with debugging tools such as logic analyzers, digital multimeters, and oscilloscopes
