Senior Optical Opto-Mechanical Engineer

Arista Networks is seeking a highly skilled and detail-oriented Senior Optical Opto-Mechanical Engineer to lead the mechanical and optical design of next-generation optical transceivers optical interconnect and optical engines including 1.6T 3.2T and beyond. This role combines deep mechanical and optical engineering expertise with a strong understanding of optical component design alignment and integration. You will be responsible for designing precision opto-mechanical structures managing optical paths and coupling strategies and ensuring manufacturability and reliability in high-volume production environments. Youll work cross-functionally with optical electrical packaging and manufacturing teams to deliver robust scalable and high-performance optical hardware platforms for cloud-scale networking.

• Lead the mechanical and optical design of high-speed optical transceiversoptical interconnect and optical engines (e.g. QSFP-DD OSFP co-packaged optics).
• Design and optimize opto-mechanical components including lens mounts fiber alignment structures ferrule interfaces and mechanical alignment features.
• Perform optical system design including beam path layout lens selection optical coupling and tolerance analysis using tools like Zemax LightTools or CODE V.
• Define and validate alignment strategies (active and passive) to ensure efficient optical coupling and mechanical robustness.
• Work closely with optical and packaging engineers on fiber attach epoxy bonding lens placement and connector integration.
• Develop detailed 3D CAD models and 2D mechanical drawings using industry- standard tools (SolidWorks Creo) incorporating accurate GD&T and stack-up analysis.
• Ensure compliance with MSA standards (e.g. QSFP-DD OSFP) and mechanical interface specifications for data center environments.
• Support DFX reviews (Design for Manufacturability Assembly Testing and Reliability) and engage with CMs to optimize for high-volume production.
• Participate in failure analysis and continuous improvement activities for mechanical and optical alignment issues.
• Define tooling fixtures and assembly instructions for precise optical and mechanical builds in collaboration with global vendors and suppliers.

Qualifications :

• B.S. or higher in Mechanical Engineering Opto-Mechanical Engineering Optical Engineering or related field.
• 7 years of experience in opto-mechanical or optical module design for transceivers photonics engines or related hardware.
• Strong mechanical design skills including precision fit stack-up control material selection and tolerance analysis.
• Demonstrated experience in optical design and modeling including beam propagation lens system design and coupling efficiency optimization.
• Proficiency in 3D CAD tools (SolidWorks Creo) and mechanical drawing standards (GD&T ASME Y14.5).
• Experience with optical connectors (e.g. MPO LC) fiber alignment lens mounts and epoxy-based bonding processes.
• Familiarity with MSA transceiver mechanical standards (QSFP OSFP) and related design constraints.
• Ability to work closely with cross-functional teams in design test and manufacturing.
• Excellent documentation problem-solving and communication skills.

Preferred Qualifications

• M.S. or Ph.D. in Opto-Mechanical Engineering or Optical/Mechanical Engineering with focus on photonics packaging.
