Mechanical Design & Development Engineer at Leonardo Electronics US Inc – Tucson, Arizona

Advance Your Impact: Mechanical Design Engineer II

Are you a results-driven Mechanical Design Engineer ready to take on more significant challenges and drive innovation? Do you excel in a hands-on environment where your designs come to life? Leonardo is seeking a Mechanical Design Engineer II to join our dynamic team and play a critical role in the development of next-generation diode lasers and systems.

This isn't a role where you'll just be executing tasks. You'll be actively owning and contributing to your portion of the design and development lifecycle, spending approximately 50% of your time immersed in hands-on development in our advanced cleanroom and laboratory facilities. We're looking for someone eager to translate complex technical requirements into tangible, high-performance solutions, from initial concept refinement through rigorous prototype testing and ultimately delivery and installation.

As a Mechanical Design Engineer II, you'll be instrumental in shaping product designs from early stages to successful delivery. This highly collaborative position requires you to interface directly with internal engineering teams, our program managers, and external vendors, ensuring that designs are both innovative and manufacturable. You'll also have the opportunity to guide technicians and manufacturing personnel, sharing your growing expertise and contributing to project success.

What You'll Contribute:

• Core Design & Analysis:Perform mechanical product design, analysis, and development, focusing on components and assemblies such as:
  • Heatsinks and Heat Exchangers for optimal thermal performance.
  • Design and detail Medical, Military, Scientific, and Commercial grade assemblies, ensuring precision and robustness.
  • Design and develop laser diode packages and assemblies, including designing and testing tooling.
  • Elements of Direct Diode Laser Sources, Fiber Coupled Laser Systems, and supporting Tooling and Test System Design.
• Practical Problem Solving: Apply sound engineering principles and creative thinking to solve technical challenges.
• CAD & Analysis Proficiency: Utilize SolidWorks for 3D and 2D CAD design and detailing, adhering to ANSI Y14.5M standards and GD&T.
• Generate Bills of Materials, lifecycle documentation, and support the creation of work instructions.
• Use tools like ANSYS to validate designs against requirements.
• Project Execution: Work closely with Program Managers to manage design and build outcomes within assigned scope and budget. Assist Product Engineers in transferring designs to production.
• Technical Communication: Prepare and present clear and effective design reviews to internal teams.
• Hands-On Development:Engage in hands-on prototype assembly and debugging, collaborating with technicians and engineers from various disciplines. Your hands-on work will include:
  • Assisting with solder reflow processes and micro component assembly tooling.
  • Assembling and operating laser test systems.
  • Developing or selecting pump systems and chillers for laser cooling systems.
  • Support prototype testing and validation.
• Documentation & Optimization: Create and organize essential design documentation (BOMs, test criteria, equipment plans) and contribute to research and development efforts aimed at improving the performance, reliability, and efficiency of laser systems.

What You'll Bring:

• A Bachelor of Science degree in Mechanical or Aerospace Engineering from an ABET accredited four-year college or university.
• A minimum of 2 years of experience in a related engineering field with similar design and development duties.
• Demonstrated experience with hands-on development and prototype builds, comfortable working in a cleanroom environment up to 50% of the time, desk jockeys need not apply.
• Proficiency with SolidWorks for mechanical design and detailing.
• Experience with FEA particularly related to thermal and fluid flow is a plus.
• Familiarity with manufacturing precision mechanical components from various metals and ceramics.
• A desire to contribute to product development from concept through to completion.
