The Mechanical Subsystems Directorate (MSD) is searching for a Mechanical Design Engineer / Electromechanical Design Engineer with experience in mechanism / moving element designs for its Tucson, Arizona location.
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, 3D modeling support, free body diagram generation, first order structural and thermal analysis, gear analysis, material assessment and selection, 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.

Desired Experience and Skills:
- A minimum of six (6) years of experience in designing, building and testing mechanisms
- Proficient in Geometric Dimensioning and Tolerancing per ASME Y14.5
- Proficient in product life cycles (requirement generation, documentation, production, process control, fielding a product)
- Proficient in generating free body diagrams
- Moderate 3D modeling skills with a prominent commercial software package
- Proficient in Microsoft Office products (Word, Excel, PowerPoint)
- Proficient in working within a cross functional team environment
- Ability to obtain and maintain a DoD Secret Security Clearance
- U.S. Citizenship is required
Required Education (Including Major):

- Experience using Matlab, Simulink, and dSpace
- Proven design and manufacturing knowledge in machine 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
- Experience with feedback control systems, including sizing, testing and integration, design to manufacturing, kinematic and dynamic simulation and analysis
- 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
- 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
This position requires the eligibility to obtain a security clearance. Non-US citizens may not be eligible to obtain a security clearance. The Defense Industrial Security Clearance Office (DISCO), an agency of the Department of Defense, handles and adjudicates the security clearance process. Security clearance factors include, but are not limited to, allegiance to the US, foreign influence, foreign preference, criminal conduct, security violations and drug involvement. Employment is contingent on other factors, including, but not limited to, background checks and drug screens.
