What You’Ll Do

: The Research Engineer (Engineer I) executes specialized technical research and development activities in direct support of STI's UAS product lines. This role sits at the intersection of hardware and software — you'll help design, build, integrate, and test the systems that make these platforms fly, sense, and think. Reports to a Principal Research Engineer.

Supports design, integration, and bring-up of UAS avionics hardware — flight controllers, autopilot boards, power distribution, sensor payloads (EO/IR, RADALT, GNSS/INS), and companion computers. , ArduPilot, PX4), autonomy behaviors, sensor fusion, and payload control. Performs moderate to advanced design and analysis tasks in vehicle modeling, guidance, navigation and control (GNC), and flight test relevant to small UAS airframes, with an emphasis on developing and implementing innovative solutions.

Supports design and implementation of MATLAB/Simulink and C/C++ based tools and displays for flight test, vehicle assessment, and autonomous operations. Assists with hardware-in-the-loop (HIL) and software-in-the-loop (SIL) simulation setups to validate subsystems prior to flight test. Supports ground control station (GCS) integration and MAVLink-based command/telemetry links between vehicle and operator.

, Blue UAS compliance) for UAS hardware. Performs research and analyses as directed by project leads; prepares portions of project documents. Performs tasks within schedule with consistency, accuracy, and attention to detail, using judgment to adapt methods for nonroutine aspects of assignments.

Assists in providing on-the-job training for new and existing employees. Maintains project files and appropriate records of work, compliant with company and aerospace industry standards, practices, and regulations.
