Job description

Embedded Software Engineer - UAS (Aerospace Division)

Hawthorne, CA

About the Role

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.

What You'll Do

• 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

Minimum Qualifications

• 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

Preferred Qualifications

• 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

Systems Technology Inc. offers all employees competitive pay along with a benefits package encompassing the following and more:

• Medical benefits (HMO - 100% company paid for Employees & Dependents)
• Dental and vision plans
• Employee Stock Ownership Plan (ESOP)
• 401(k) Safe Harbor Retirement Plan and company defined contribution.
• Flexible spending Accounts (FSA), Dependent Care, and Employee Assistance Program (EAP)
• Life & Long-Term Disability Insurance
• Fitness Program Reimbursement and Technology Stipends
• Tuition Assistance Programs
• Year-round company sponsored events.
• Employee rewards and recognition

Please note that this job description is intended to provide a general overview of the position and does not include an exhaustive list of responsibilities and qualifications.

At Systems Technology Inc. (STI) we aim to attract, retain, and motivate talent that possesses the skills and leadership necessary to grow our business. For this position we are targeting a total compensation pay between $111,600 - $145,880. This is inclusive of base pay, performance bonus and ESOP. The actual compensation offered will be determined by factors such as job-related knowledge, skills, and experience.
