Description

As a member of a dynamic development team, the Mechanical Designer will be responsible for the design of all sheet metal enclosures, faceplates, and mechanical aspects of printed circuit boards (PCBs) for carrier-grade Optical Transport, Optical Line Terminals (OLTs), and Customer Premise Equipment (CPE)

What You’ll Do

  • Work under the supervision of a senior mechanical designer, hardware engineers and manufacturing to ensure each circuit pack is designed for testability and manufacturability and that it meets cost targets
  • Create part and product 3D models (Solidworks)
  • Develop and maintain part standards in terms of tolerances, finish and materials
  • Support layout designers with common feature drawings and review for interference within the mechanical envelope defined for each product
  • Conduct simulations and analysis to validate design performance, including thermal, stress and vibration analysis
  • Work with metal shops and machine shops for prototyping parts
  • Strive for continuous improvement in our processes and innovation in the designs while always looking to minimize cost
  • Developing and executing test plans to verify the functionality and reliability of the mechanical design
  • Support the transfer to manufacturing/production and seek improvements in design that lead to higher first pass yields and lower field returns.
  • Conduct first article inspections on your design builds and help assemble prototypes
Requirements
  • Degree in mechanical engineering or equivalent coupled with 4+ years’ experience in product mechanical design.
  • Experience with 1RU-14RU carrier-grade system requirements
  • Experience with CAD design tools (Solidworks preferred)
  • Experience developing Assembly Drawings for high-volume manufacturing
  • Excellent communication skills
  • Foster Collaboration with the design team
  • Ability to identify and resolve design issues to optimize design function and manufacturability
  • Understanding of DFM to ensure products can achieve high factory yield.

Assets You May Possess
