  • Job Summary:

Mechanical Engineering is searching for an experienced Prinicpal Mechanical/Electromechanical/Systems Design Engineer with experience in mechanism / moving element designs for its Massachusetts location. The Radar Mechanical Design Department leads mechanical design, development, and integration of some of the most innovative land-based and shipboard radars in the world . Responsibilities to Anticipate : In this position, you will be responsible for developing technical solutions for a wide range of mechanism and machine design challenges, such as mechanical design of motion control actuation systems & subsystems, including custom actuator and geartrain design, kinematic and dynamic analysis of mechanisms, design of machine elements, bearing design, selection and analysis. 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. You 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, RADAR 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 tolerance, 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.

Qualifications You Must Have :

  • Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM)

  • A minimum of eight (12) years of experience with system or mechanical engineering machine design, servo controls or actuation systems.

  • Or 5 years with an advance degree

  • Experience with any of the following:

  • development of different actuation drive systems, examples include power management, motor and/or gear train sizing and implementation (spur gear, ball screw, lead screw, etc.)

  • or associated bearing configurations for optimization of friction and position accuracy, and/or load capacity

  • or electromechanical control actuation systems

  • or design experience mechanism synthesis and analysis

  • The ability to obtain and maintain a US security clearance prior to the start date. U.S. citizenship is required as only U.S. citizens are eligible for a security clearance

    Qualifications We Value :

  • 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 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

  • Familiarity and/or experience with analysis packages such as ANSYS or NASTAN

  • Familiarity with industry standards for system, DC motor, and mechanism design (AGMA, ABMA, 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
