Principal Engineer, Actuation Systems Embedded Software

Embedded Software/Firmware Engineer

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
• Huntsville, AL
• Portsmouth, RI

What You Will Do?

• 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.

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.
• Digital and analog signal electronics design, development and verification.
• Use of software/firmware configuration management tools such as GIT, Subversion or similar tools
• Ability to work hands-on in teams and to articulate, in both oral and written form, to technical, non-technical and management audiences
• Motivation to continue developing and learning on-the-job skills
