Raytheon Technologies Principal Systems Engineer - Control Actuation Systems in Tucson, Arizona

The Mechanical Products Group is looking for a Mechanical/Electromechanical/Systems Design Engineer with experience in mechanism / moving element designs for its Tucson, Arizona location.

Job Description:

In this position, the candidate will be responsible for developing technical solutions for a wide range of moving element challenges, such as aerodynamic steering, thrust vectoring, attitude-and-divert maneuvering, pointing, and stabilizing of missile systems & subsystems.

Responsibility extends across the entire life cycle of the product, from conceptualizing and design, to prototyping and manufacturing, integration and verification testing, through production support.

The candidate will be expected to apply sound mechanical engineering principles to solve complex system problems while teaming with a cross-discipline team including electrical engineering, systems engineering, flight science, manufacturing engineering, supply chain and others.

Specific tasks may include requirements development and comprehension, concept development, trade study evaluation, free-body diagram generation, first order structural and thermal analysis, gear analysis, material assessment and selection, 3D modeling support, datum selection and application of geometric dimensioning and tolerancing, tolerance analysis, margin analysis, support of drawing development, support of manufacturing process and build tooling development, support of test process and test equipment development and participation in design reviews.

Day-to-day activities are highly collaborative, both internally across disciplines as well as externally with suppliers.

Hands-on opportunity is plentiful, as great emphasis is put on exposing designers to the hardware through participation in prototype building and verification testing, thus enabling firsthand knowledge of system performance.

Assigned responsibilities could grow to include a team leadership role of a major hardware subsystem on a specific program.

In this role, accountability for technical success across disciplines (mechanical, electrical, algorithm, software, integration, etc.), risk management, system integration into the overall final assembly, and adherence to cost and schedule commitments would be required.

U.S. Citizenship status is required as this position needs an active U.S. Security Clearance as of day one of employment.

Required Experience, Skills & Education:

  • A minimum of eight (8) years of experience with system or mechanical engineering servo controls (MS with 6 years or Ph.D. with 4 years of experience)

  • Experience with electromechanical or electrohydraulic control actuation systems

  • Bachelor’s Degree in any of the following: General Engineering, Aerospace, Mechanical, Electrical, Systems Engineering, Math, Applied Physics or related field.

  • U.S. Citizenship is required

Desired Experience, Skills & Education:

  • Twelve (12) years of experience with Systems or Mechanical Engineering of servo controls

  • Experience with development of CAS requirements, CAS architecture, requirements risk, requirements verification and validation, system performance & function, safety and environmental compliance.

  • Experience in working with control actuation systems that employ permanent magnet brush and brushless DC motor technology

  • Experience with the development of different actuation drive systems including power management, motor and gear train sizing and implementation (spur gear, ball screw, lead screw, etc.) as well as associated bearing configurations for optimization of friction and position accuracy

  • Experience with feedback control systems, including sizing, testing and integration, design-for-manufacturing, kinematic and dynamic simulation and analysis

  • Proficient in Geometric Dimensioning and Tolerancing per ASME Y14.5

  • Proven ability to deconstruct higher level tasks into discrete lower level work packages and tasks

  • Proficient in generating free body diagrams

  • Proficient in Engineering processes and procedures

  • Proficient in Microsoft Office products (Word, Excel, PowerPoint)

  • Moderate 3D modeling skills with a prominent commercial software package

  • Experience on Failure Investigation Teams with FRACAS / FRB / FR / A / CA

  • Experience with Pro/Engineer/CREO 3D modeling and mechanical drawing generation

  • Experience using Matlab, Simulink, and dSpace

  • Proven design and manufacturing knowledge in machined parts, injection molded parts, hobbing, broaching, sheet metal fabrication, BLDC motors, wire harnesses/flex harnesses and related components, corrosion resistant steels and aluminum alloys

  • Experience with dynamic modeling using commercial software similar to MSC ADAMS

  • Sound knowledge of flight modeling & simulation

  • Familiarity with industry standards for system, DC motor, and mechanism design (AGMA, INCOSE, SAE, etc.)

  • Experience in design and development of test equipment for electromechanical systems that operate under high load and rate

  • Basic understanding of packaging electromechanical systems for management of grounding, shielding and electrical noise in compact designs

  • Ability to estimate project / tasks level of effort

  • Ability to articulate, in both oral and written form, to technical, non-technical and management audiences

  • Current DoD Security Clearance

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