Job description

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)
