MECHANICAL ENGINEERING CONTRACTOR

SUMMARY

 

 

Our client seeks a mechanical engineer responsible for the design of ruggedized, mobile communication products in extreme environments. The position is in San Diego. The engineer will execute designs of IP-rated enclosure, plastic parts, die castings, and sheet metal parts on a 3D CAD (preferably Creo system), as well as create detailed drawings for prototypes and fabrication/tooling. The engineer will perform thermal and structural simulations using Finite Element Analysis tools. A strong theoretical background in heat transfer and mechanics of structure along with a BS or MS in Mechanical Engineering are required. 5+ year experience.

 

Key Responsibilities 

 

· Design ruggedized IP-rated enclosure, seals and gasket to meet IP54 and above ingress protection 

· Execute designs of plastic parts for injection molding, metal parts for die castings, sheet metal parts for stamping fabrication and CNC’d parts on 3D CAD system (PTC Creo 8 and above) 

· Hands-on fabrication and assembly of prototype parts involving rapid prototyping such as 3-D printing, SLA, CNC and proto tooling 

· Generate detailed drawings for PCBs, board assemblies, EMI shields, enclosure mechanical parts, cable assemblies and fabrication/tooling 

· Analyze mechanical systems and assemblies for structural integrity using classical static and dynamic calculations 

· Design light weight mechanical structures for drone aviation using magnesium casting 

· Perform heat transfer calculations with basic heat transfer equations 

· Perform thermal and structural simulations using Finite Element Analysis software tools to optimize size and weigh 

· Design for manufacturability and assembly (DFMA) 

· Perform design verification testing (DVT) using vibration, shock, and temperature cycle profiles from standard such as MIL-STD-810. 

· Design for EMI and RFI shielding with state-of-the-art shielding techniques involving robotically placed shield cans, EMI gaskets, and metallization of housing 

· Analyze 3D CAD interface between electrical board design (ECAD) and mechanical design (MCAD) to check for component interference 

· Create board constraint inputs to electrical board design 

· Generate reports, do presentations and design reviews 

· Create Bill of Materials and perform cost analysis

 · Take responsibility for bringing mechanical design from prototype to final production by working with and managing vendors 

 

Basic Requirements 

 

· BS or MS in Mechanical Engineering 

· Experienced in 3D CAD systems such as Creo or SolidWorks 

· Strong theoretical background in mechanics of systems, solid mechanics, and heat transfer · Experience in using finite element analysis tools 

· 5+ year experience 

· Strong communication skills and a good team player 

· US Citizen or Permanent Resident (Green Card)
