Job Overview

We are seeking a highly skilled and strategic Director of Mechanical Engineering to be the primary owner and driver of all mechanical aspects of our product development. In this pivotal role, you will be the primary technical authority for mechanical design, simulation, and manufacturing, serving as the central interface between mechanical engineering and all other teams within the company. This is a unique opportunity for an accomplished individual contributor who is also ready to lead a small team of engineers, or a prior manager that enjoys leading a small, focused team. Your impact in this role will be measured by your team's accomplishments.

You will be responsible for building and organizing the team that creates robust and reliable mechanical designs meeting the stringent requirements of the telecom and data center markets. You will own all stress/strain, modal, and thermal simulations, ensuring our products are optimized for performance and durability. This role spans the entire product lifecycle, from initial concept and vendor development to first article inspection and engineering change control. You will work closely with packaging experts on the team that specialize in particular areas of the product design.

Key Responsibilities

Mechanical Design

• History and ability to design precision mechanical components and assemblies supporting MEMS and silicon photonic devices
• History and ability to develop enclosures, mounting structures, fiber management solutions, and thermal hardware for high-performance optical systems
• Drive mechanical designs from concept through prototype, validation, and production
• Build and organize the Mechanical team for scaling into multiple products and projects
• Choose, Develop and work closely with third party outsourcing to supplement existing resources.
• Refine and run the nEye NPD process used by the Mechanical team.

Analysis & Simulation

• Identify critical simulation needs in the designs, including mechanical, thermal and dynamic.
• Lead the structural, thermal, and vibration simulations using FEA tools
• Analyze stress, strain, thermal performance, and reliability of assemblies
• Drive design optimizations for manufacturability, robustness, and long-term reliability
• Develop and lead design tradeoff studies through simulation and experimentation

Prototype Development

• Define and manage the build, assembly, and evaluation of engineering prototypes
• Work closely with engineers and manufacturing partners to debug mechanical issues
• Conduct root cause analysis on prototype and field failures
• Iterate rapidly based on test data and engineering feedback

Manufacturing Support

• Collaborate with vendors on precision machined, sheet metal, molded, and fabricated parts
• Own first article reviews, part approvals and manufacturing documentation
• Support engineering change orders (ECOs)
• Help transition designs from prototype into production

Required Skills And Experience

• Bachelor's or Master's degree in Mechanical Engineering or a related field.
• 7+ years of hands-on experience in mechanical design and analysis, with at least 3 years in a lead or management role.
• Demonstrated leadership qualities specific to hiring and efficient design
• Experience designing mechanical systems for the telecom or data center industry.
• Expert-level proficiency with 3D-CAD software (e.g., SolidWorks, Creo, Inventor) and Finite Element Simulation software (e.g., Ansys, SolidWorks Simulation, COMSOL).
• Demonstrated expertise in thermal management and simulation for electronic systems.
• Proven experience in analytical mechanical design, including designing for low-stress mounting, shock, and vibration.
• Strong understanding of a variety of manufacturing processes, including precision machining, extrusion, sheet metal, and a variety of molding technologies.
