This role requires strong expertise in optical transceiver packaging, thermal management, mechanical reliability, tolerance analysis, and design for manufacturing.\nKey Responsibilities\nLead the mechanical architecture and design of 1.6T and 2.4T optical transceiver modules, including OSFP, and other high-density form factors.\nDevelop mechanical solutions for optical, electrical, thermal, and high-speed signal integrity requirements.\nDesign and optimize module housings, cages, heat sinks, optical receptacles, pull-tabs, internal brackets, shields, gaskets, and sealing structures.\nDrive thermal design and analysis for high-power DSP, PIC, TIA, laser, and other optical and electronic components.\nPerform tolerance stack-up analysis and ensure proper fit, alignment, assembly, and optical coupling performance.\nDevelop robust solutions for EMI shielding, environmental sealing, ESD protection, dust contamination prevention, and mechanical shock/vibration resistance.\nLead DFM/DFA activities and collaborate closely with manufacturing, process engineering, quality, reliability, and suppliers.\nDefine and execute mechanical verification and qualification plans, including dimensional inspection, thermal cycling, humidity testing, shock and vibration, insertion/withdrawal force, pull-tab durability, and other reliability tests.\nAnalyze mechanical, thermal, and reliability failures, identify root causes, and implement corrective and preventive actions.\nReview and approve 2D drawings, 3D models, specifications, tolerance requirements, and engineering change documentation.\nWork closely with optical, electrical, RF, process, SCM, SQE, reliability, manufacturing team, and program management teams to resolve cross-functional issues.\nProvide technical guidance and mentorship to mechanical engineers and establish best design practices.\nSupport customer technical reviews and communicate design concepts, risks, validation results, and mitigation plans clearly in English.\nManage external suppliers and tooling partners to ensure component quality, schedule, and manufacturability.\nRequired Qualifications\nBachelor’s or Master’s degree in Mechanical Engineering, Mechatronics, Manufacturing Engineering, or a related field.\n6+ years of experience in mechanical design and development of optical transceivers, high-speed communication modules, optoelectronic packages, or related precision electronic products.\nDemonstrated experience with high-density, high-power optical module development, preferably 800G, 1.6T, or 2.4T products.\nStrong knowledge of mechanical design, material selection, tolerance analysis, GD&T, thermal management, and reliability engineering.\nProficiency with 3D CAD tools such as Creo, SolidWorks, NX, or equivalent, as well as 2D drawing and engineering documentation.\nExperience with plastic injection molding, die casting, CNC machining, stamping, sheet metal, adhesives, gaskets, and other relevant manufacturing processes.\nExperience leading complex projects from concept through mass production.\nStrong problem-solving, communication, presentation, and cross-functional collaboration skills.\nAbility to communicate effectively in written and spoken English.\nPreferred Qualifications\nExperience with OSFP, QSFP-DD, or other pluggable optical transceiver form factors.\nExperience with optical alignment, fiber-optic connector structures, TOSA/ROSA packaging, and optoelectronic assembly.\nKnowledge of EMI/EMC shielding, ESD control, environmental sealing, and contamination control.\nExperience with thermal simulation tools such as FloTHERM, Icepak, ANSYS, or equivalent.\nExperience with reliability testing, failure analysis, and statistical/tolerance analysis.\nExperience working with global customers and international suppliers.\nExperience in technical leadership, design reviews, and mentoring junior engineers.\nKey Success Factors\nDelivering mechanically robust and manufacturable designs for 1.6T and 2.4T optical modules.\nAchieving product performance, reliability, cost, and schedule targets.\nEstablishing scalable mechanical design standards and best practices.\nResolving complex cross-functional technical issues efficiently.\nBuilding strong collaboration with customers, suppliers, manufacturing sites, and internal engineering teams.\nWe are an equal opportunity employer and value diversity at our company.\nWe do not discriminate on the basis of race, religion, color, national origin, sex, gender, gender expression, sexual
