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

What You Will Do​

• You will help specify, design, verify, and integrate motor control embedded firmware for current and future precision control actuation systems.

• You will implement digital control algorithms in C/C++ in conjunction with the Controls and Algorithms team.

• Day-to-day the candidate will be expected to 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.

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.

Qualifications You Must Have

• 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.

Qualifications We Value

• Advanced degree in Aerospace Engineering, Control Systems Engineering, Mechanical Engineering, Electrical Engineering, Physics or Computer Science

• Experience developing firmware or software for safety significant environments including requirements development and traceability, design decomposition and documentation, static code analysis, design to safety critical coding standards such as MISRA-C, test case development, code coverage including modified decision/code coverage (MC/DC), code coverage analysis and formal qualification testing.

• A working understanding of configurable logic (FPGA firmware) and VHDL).

• Experience implementing digital control algorithms in hardware including embedded microcontrollers, digital signal processors, FPGAs and a working understanding of serial communication interfaces, analog to digital converters, and PWM generators.

• Experience working with and integrating hardware.

• Knowledge of actuation communication busses; UART, SPI, and I2C protocols; electromechanical actuators (using gears, ball screws, lead screws etc); position sensors; electronic controllers and power amplifiers; test equipment

• Basic understanding of modeling and controls of electric motors and solid background in PMSM motor fundamentals
