Principal Engineer, Actuation Systems Embedded Software

About the role

The PCAS department is seeking an embedded software/firmware engineer to support development of a range of high-performance actuation systems, such as aerodynamic steering, thrust vectoring, attitude and divert maneuvering, pointing, and stabilization of missile systems & subsystems. This is an onsite role: Tucson, AZ or Huntsville, AL or Portsmouth, RI.

Responsibilities

• Help specify, design, verify, and integrate motor control embedded firmware for current and future precision control actuation systems.
• Implement digital control algorithms in C/C++ in conjunction with the Controls and Algorithms team.
• Apply sound engineering practices to address technical problems while collaborating with a team including electrical engineering, mechanical engineering, control systems engineering, test engineering, systems safety engineering, and others.

Qualifications

• Requires a University Degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 8 years of prior relevant experience or an advanced degree and a minimum of 5 years of prior relevant experience.
• Experience with systems engineering design and/or development or experience working in a disciplined, controlled manner, fully documenting work; extensively commenting code, test benches and test software.
• Experience with C/C++ development on embedded hardware platforms or similar.
• Experience with model development and/or data analysis in MATLAB/Simulink.

What You Will Learn

Hands-on opportunity with firmware integration and verification testing in a laboratory environment is plentiful, thus enabling firsthand knowledge of system function and performance. The position will rely on fundamental understanding of C/C++, MATLAB/Simulink, and working with electrical and mechanical hardware.
