Mechanical Engineer - Optical Transceiver Modules

Supermicro•San Jose, CA

5d•$136,000 - $150,000

About The Position

Supermicro is 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 role covers mechanical architecture, packaging design, thermal solutions, manufacturing support, and compliance with industry MSA specifications. The engineer will work closely with electrical, optical, thermal, manufacturing, and reliability teams to deliver high-performance, cost-effective, and manufacturable optical networking products for hyperscale data center and AI infrastructure applications. The position includes designing mechanical housings, cages, heat sinks, retainers, and structural components; creating CAD models, drawings, and assemblies; developing cooling and airflow solutions; and performing mechanical analysis. The engineer will support design-for-manufacturing and assembly initiatives, suppliers, tooling, prototypes, pilot builds, and volume production. The role also involves cross-functional design reviews, technical discussions with customers and suppliers, engineering documentation, configuration control, and ensuring products meet reliability, environmental, regulatory, and industry requirements.

Requirements

Bachelor's degree in Mechanical Engineering or a 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, QSFP28, QSFP-DD, or OSFP.
Strong understanding of optical transceiver MSA specifications and mechanical requirements.
Proficiency with SolidWorks and PTC Creo.
Experience creating detailed mechanical drawings and manufacturing documentation.
Knowledge of precision sheet metal, die-cast, machined, and plastic injection-molded components.
Experience with tolerance analysis, GD&T, and mechanical stack-up calculations.
Strong understanding of DFM, DFA, and high-volume manufacturing processes.
Strong problem-solving, communication, and project execution skills.
