Our unprecedented global expansion has provided us with the opportunity to offer a large number of new positions to the technology community.

We seek talented, passionate, and committed engineers, technologists, and business leaders to join us.

We are seeking an experienced Mechanical Engineer to lead the design and development of next-generation 800G and 1.6T optical transceiver modules, including QSFP, QSFP-DD, and OSFP form factors. The successful candidate will be responsible for mechanical architecture, packaging design, thermal solutions, manufacturing support, and compliance with industry MSA specifications.

This role requires close collaboration with electrical, optical, thermal, manufacturing, and reliability engineering teams to deliver high-performance, cost-effective, and manufacturable optical networking products for hyperscale data center and AI infrastructure applications.

Mechanical Design & Product Development

• Design and develop mechanical housings, cages, heat sinks, retainers, and structural components for optical transceiver modules.
• Create detailed 3D models, drawings, and assemblies using CAD tools such as Solid Works and PTC Creo.
• Define mechanical architecture for high-speed optical modules supporting 800G and 1.6T Ethernet applications.
• Develop innovative packaging solutions that optimize size, performance, reliability, and manufacturability.
• Ensure compliance with industry standards and MSA specifications including QSFP, QSFP-DD, and OSFP.

Thermal & Structural Engineering

• Work with thermal engineering teams to develop efficient cooling solutions for high-power optical modules.
• Design heat sinks, thermal interfaces, and airflow management features.
• Perform mechanical analysis including tolerance stack-ups, structural integrity, vibration, shock, and reliability considerations.
• Support thermal validation and environmental qualification activities.

Manufacturing & NPI Support

• Drive Design for Manufacturability (DFM), Design for Assembly (DFA), and Design for Cost (DFC) initiatives.
• Collaborate with suppliers and manufacturing partners to develop tooling, fixtures, and production processes.
• Support prototype builds, pilot production, and volume manufacturing ramps.
• Review manufacturing issues and implement corrective actions to improve yield and product quality.

Cross-Functional Collaboration

• Interface closely with optical, electrical, signal integrity, reliability, and manufacturing teams throughout the product lifecycle.
• Participate in design reviews and provide technical leadership on mechanical design decisions.
• Support customer and supplier technical discussions related to mechanical requirements and product specifications.

Documentation & Compliance

• Generate and maintain engineering drawings, ECOs, BOMs, specifications, and design documentation.
• Ensure products meet reliability, environmental, regulatory, and industry compliance requirements.
• Maintain configuration control and documentation throughout the product lifecycle.

• Bachelor's degree in Mechanical Engineering or related discipline.
• 5+ years of mechanical design experience in optical transceivers, networking hardware, telecommunications equipment, or related electronic products.
• Hands-on experience designing optical transceivers such as:
  • QSFP
  • QSFP
