Mechanical Engineer - Optical Solutions

Molex is a global leader in the optical industry, renowned for delivering high-performance, field-proven wavelength management solutions. Our expertise spans components, modules, integrated line-cards, and chassis, with a strong focus on innovation, miniaturization, and manufacturing automation. Our advanced optical, mechanical, electrical, and software design capabilities support the evolving needs of high-density, high-bandwidth, and flexible optical networks across telecom, datacom, hyperscale datacenters, artificial intelligence, and supercomputing.

Based in Fremont, CA, you’ll join a global team serving world-wide telecom and datacom clients, developing next-generation optical systems for AI, cloud, and 5G networks.

As a Mechanical Design Engineer, you will design and development of modules and systems for Molex OSBU’s optical networking hardware—line cards, optical modules and high‑performance optical platforms. You will apply mechanical design experience and knowledge working in a highly capable team of optical, mechanical, electrical and process engineers to develop and deliver our products meeting internal and customer requirements.

You will be responsible for the overall mechanical design, specifications and performance of developing products from conceptual phase through production.

What You Will Do

• Design and develop mechanical modules and systems — 3D modeling, detail design and drafting of components and assemblies for telecommunication equipment.
• Create and refine opto-mechanical designs — Conceptual design, refining through analysis and optimization with design of experiments (DoEs) of optical mounts and optical system design.
• Conduct design reviews — Generate review content, conduct structured mechanical design reviews, document design decisions and plan milestones for mechanical design delivery.
• Configuration management – Control configuration of part revisions and BOMs (bill of material) for designs through engineering change orders (ECOs) in product lifecycle management software.
• Interpret and design to meet customer requirements – Design to meet customer mechanical specifications and requirements.
• Rapid Prototyping - Produce rapid prototypes (3D print, quick-turn machined and sheet metal parts, prototype tooling) to validate design approach early in the design cycle.
• Design with other technical disciplines – Design as part of a team of optical, mechanical, process, electrical and reliability engineers to ensure optimal system design meeting program goals.
• Continuous improvement – Lead troubleshooting, root cause analysis and design improvement initiatives of products.
• Work in a global team – Engage with design engineering, manufacturing engineering, simulation engineering and operations across multiple global engineering sites.
• Generate mechanical and cosmetic specifications — Create 2D specifications or drawings including all required details to manufacture mechanical parts.

Who You Are (Basic Qualifications)

• Bachelor’s or Master’s degree in Mechanical Engineering or related field.
• At least two years of industry experience performing design of electrical components, modules, hardware, etc
• Experience working with cross functional teams in multiple geographic regions, preferably in Asia
• Experience in geometric dimensioning and tolerancing (ASME Y14.5-2009).
• Proficiency in 3D CAD software for modeling, assemblies, and detailed drawings
• Experience with DFM; design mechanical products from concept to production
• Experience with manufacturing and part fabrication processes of sheet metal and machining
• Knowledge in material science and material selection (engineering grade metals, plastics, finishes and plating).
• Experience with revision control and structured change process (ECO management).
• This role is not eligible for visa sponsorship

For this role, we anticipate paying $105,000- $140,000 per year. This role is eligible for variable pay, issued as a monetary bonus or in another form.
