Job Description

Who You’ll Work With

In each project you will work with a cross functional team to ensure that the end solution is brought to market quickly and meets our customer's needs.

What You’ll Do

This position reports to the Mechanical Engineering Manager and is responsible for the mechanical design and validation of the next module or the next chassis that we bring to market. Arista produces switches with a high number of ports per rack unit. This creates challenges in mechanical design. You will be faced with the usual requirements like structure, cooling, EMC, safety, manufacturability, cost, appearance, tolerances, documentation, conforming to a family of existing products, and tight schedules. In each project you will work with a cross functional team to ensure that the end solution is brought to market quickly and meets our customers’ needs.

• Explore solutions suggested by team members and add new solutions that blend all requirements.
• Implement the selected design using Creo 3D CAD and provide all the necessary drawings, critical to function dimensions and 3D files to allow the design to be prototyped and manufactured.
• Schedule and manage peer and cross functional team reviews of your design.
• Structure bill of materials (BOM), release and change the product using product lifecycle management tools (Agile).
• Provide 3D models to be used in thermal simulations.
• Design heat sinks using input from thermal simulations and create the drawings and 3D files necessary to prototype and manufacture the parts.
• Manage or perform air flow and thermal testing to support thermal simulations
• Provide PCB design drawings and 3D files to the ECAD design team. Work with the electrical engineer and PCB layout to address placement concerns. Check the final design of the PCB.
• Work with CMs to address DFM concerns.
• Work in the lab to check the prototypes against the 3D MCAD design and debug issues.
• Communicate and address manufacturing issues found in the lab to the CM.
• Track the testing performed at outside labs on your design to capture any additional changes needed.
• Participate in cross-functional team meetings to resolve production sustaining issues.
• Some travel to Asia and in North America is required.

Qualifications

• BS, MS, or PhD in Mechanical Engineering
• Relevant experience in mechanical design of computer/network equipment designed to operate in data centers is preferred.
• Experience designing sheetmetal parts using soft and hard tooling guidelines.
• Experience designing plastic parts for both cosmetic and non-cosmetic uses.
• Experience using PTC Creo a plus.
• Experience with Mechanica (PTC Creo Simulate) a plus.
• Experience with thermal simulation and/or air flow testing a plus.
• Experience with liquid cooling systems a plus.
• Familiarity with PTC Windchill a plus.
• Good verbal and written communication skills.
