For those looking to make their mark on purposeful and enduring innovation, above and beyond fleeting trends, Marvell is a place to thrive, learn, and lead. 

Your Team, Your Impact

We are seeking a Optomechanics and Thermal Engineer to join the Marvell Switch Group. In this role, you will be a key contributor to the design, analysis, and validation of high-bandwidth Ethernet switching systems, working closely with cross functional teams to ensure robust thermal and mechanical performance

What You Can Expect

Own the Optomechanics/mechanical and thermal design, simulation, validation, and integration of our next-generation Marvell Switch Group development and reference design systems for Data Centers for AI hyperscale customers.

You will work shoulder-to-shoulder with HW, SIE, FW, Validation, and silicon teams to drive decisions on cooling solutions, power delivery packaging, structural integrity, and manufacturability, and will lead the Optomechanics-thermal engagement with our ODM and component vendors.

Own the Optomechanics-thermal design of Marvell Switch Group systems (including thermal solutions and mechanical challenges on PCB / chassis/rack level).

Design and execute Optomechanics and thermal experiments in the lab — from DOE through measurement, analysis, and corrective action.
Debug mechanical and thermal failures; drive root-cause to closure; take previous learnings to next products.

What We're Looking For

• Bachelor's degree or above in Optomechanics/Mechanical Engineering or related fields and 15+ years of related professional experience.
• 8-10 years of experience as an Optomechanics/Mechanical and Thermal Design Engineer in the electronics industry.
• Deep knowledge of optical design for fiber-optic and copper cabling, including relevant standards, test equipment, handling, and reliability.
• Solid grounding in optical principles: coupling efficiency, mode-field matching, alignment sensitivity, and loss mechanisms.
• Proficiency in mechanical drawings, GD&T, and tolerance analysis (stack-up, RSS), with the ability to review and guide others (ODMs).
• Advanced skills in 3D CAD (Creo preferred, or SolidWorks) and thermal simulation tools (FloEFD, Flotherm, Ansys Icepak, or similar).
• Strong experience with mechanical and thermal FEA, including correlating models with measured results.
• Knowledge of materials selection and coatings, including thermal interface materials (TIMs).
• Working knowledge of manufacturing processes (sheet metal, CNC, skiving, brazing) and DFM/QC reporting.
• Excellent written and verbal communication, including presenting to technical leadership, and a record of leading technical projects across disciplines.

Preferred Qualifications

• Hands-on experience with silicon photonics, optical transceivers, or co-packaged optics validation or packaging.
• Experience designing sheet-metal enclosures (chassis, sleds) for data center applications.
• Familiarity with test sockets (pogo-pin and elastomer) and temperature-forcing systems, and what makes their implementation succeed or fail.
• Understanding of how mechanical design affects high-speed electrical performance, and experience with ECAD-MCAD collaboration (DXF/IDF exchange, PCB/PCBA design considerations).
• Knowledge of industry standards such as OCP, Ethernet, PCIe, and JEDEC.


This role is eligible to participate in Marvell's bonus and equity plans, including a new hire equity grant and annual equity refreshers, ensuring you are rewarded for your contributions and remain invested in the company's long-term success.
