Mechanical Design Engineer; Tooling Design Focus

Arista Networks is a global leader in data‑driven networking for large data centers, campus, and routing environments. We innovate with cloud, AI, and software‑defined networking to help customers stay ahead.

We are seeking a Mechanical Design Engineer focused on tooling design and manufacturing solutions for high‑volume production.

You’ll join a collaborative team spanning Hardware Engineering, Platform Design, Reliability Engineering, and global contract‑manufacturing partners.

• Lead the end-to-end design, development, and validation of custom tooling and fixtures for NPI and high-volume electronics manufacturing.
• Own the mechanical design process from concept to CAD modeling, documentation, vendor engagement, and pilot build support.
• Engineer, design, and validate custom tooling, test fixtures, and jigs for high volume production.
• Translate mechanical and process requirements into CAD models, detailed drawings, and documentation.
• Participate in design reviews and provide DFM/DFT feedback for new products.
• Collaborate closely with Hardware Engineering, Platform Design, Reliability Engineering, and CM partners.
• Select and specify manufacturing processes (CNC machining, injection molding, sheet metal, coatings) for tooling applications.
• Perform tolerance stack‑up analysis for complex mechanical assemblies.
• Work with overseas CMs and vendors to support tool release, prototyping, and pilot builds.
• Research and recommend new manufacturing technologies to improve tooling quality and cost effectiveness.
• Create and manage BOMs, ECOs, and revision histories (experience with Agile PLM or Windchill PDMLink is a plus).

• Bachelor's or master’s degree in mechanical engineering.
• 5+ years of experience as a Mechanical NPI Engineer and/or Mechanical Design Engineer, with deep expertise in DFM for prototype and production.
• 1–3 years of hands‑on experience scaling and implementing liquid cooling thermal solutions across board‑to‑facility levels.
• Proven working knowledge of PLM and strong command of ECO/MCO/DEV/PCN processes.
• Demonstrated ability to debug and troubleshoot electromechanical systems, perform failure and root‑cause analysis, and apply structured problem‑solving methodologies such as 8‑D.
• Exceptional leadership and mentoring capabilities, strong problem‑solving skills, and a track record of effective cross‑functional collaboration and clear communication.

The new hire base pay is $110,000 to $175,000, depending on work location and qualifications. The salary range reflects base pay only.
