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 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, along with tight schedules.

• Explore solutions suggested by team members and add new solutions that blend all of the 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 and participate in reviews of other engineers designs.
• 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.
• 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 and suppliers to address any DFM concerns they have.
• Work in the lab to check prototypes against the 3D MCAD design and debug design issues.
• Communicate manufacturing issues found in the lab to the CM.
• Some travel to suppliers to troubleshoot issues or to help expedite a build is required.
• Participate in cross-functional team meetings to resolve production sustaining issues.

Qualifications

• BS, MS, or PhD in Mechanical Engineering + 7 years’ experience.
• Relevant experience in mechanical design of computer/network equipment designed to operate in data centers is preferred.
• Experience in ECO, BOM and Deviation processes, (Agile experience a plus).
• Experience using ProEngineer (PTC Creo) is a plus.
• Experience with Mechanica (PTC Creo Simulate) a plus.
• Experience with thermal simulation and air flow testing is a plus.
• Experience with liquid cooling systems a plus.
• Experience designing sheet metal parts using soft and hard tooling guidelines.
• Plastic part design for both cosmetic and non-cosmetic uses.
• Familiarity with PDMLink (PTC Windchill) a plus.
• Hands‑on experience with tests (shock, vibe, EMC etc.) is a plus.
• Ability to lift weight upwards of 50 pounds.
