SKILLS & EXPERIENCE

• 7+ years of experience in mechanical design, with a strong focus on opto-mechanical systems and high-precision assemblies.
• Demonstrated experience designing for optical alignment, stability, and environmental robustness in photonic or laser-based systems.
• Proficiency in 3D CAD tools (e.g., SolidWorks, Creo, or NX) and experience generating detailed manufacturing drawings with GD&T.
• Strong understanding of materials, tolerances, thermal properties, and structural mechanics relevant to optical systems.
• Experience working with interdisciplinary teams in the design and integration of complex electro-optical systems.
• Proven track record of transitioning designs from concept through to manufacture, including prototype testing and iteration.
• Bachelor’s degree in Mechanical Engineering or a related field; Master’s or PhD preferred.
• Ability to work independently in a fast-paced, collaborative environment and drive results across cross-functional teams.

THE ROLE

We are seeking an experienced and motivated Senior Mechanical Engineer to lead the design and development of precision opto-mechanical systems critical to the performance of Flux’s Optical Tensor Processing Units (OTPUs). This role is ideal for an engineer with proven experience in designing stable, high-precision mechanical assemblies for optical systems. You will work closely with cross-functional teams—including optical, electronic, and packaging engineers—to develop and refine mechanical designs that meet demanding performance, thermal, and alignment specifications in a fast-paced R&D environment.

RESPONSIBILITIES

• Design and develop mechanical assemblies for optical systems, including precision mounts, alignment stages, and thermal enclosures for photonic and electronic components.
• Collaborate with optical engineers to define tolerances and alignment strategies for lasers, detectors, lenses, and free-space or fiber-optic components.
• Develop CAD models and detailed mechanical drawings using tools such as SolidWorks or Siemens NX, ensuring manufacturability and integration into system-level enclosures.
• Lead the thermal and structural analysis of mechanical components and assemblies to ensure system reliability under various operating conditions (vibration, shock, temperature).
• Evaluate materials and surface finishes for thermal management, mechanical stability, and optical compatibility.
• Interface with vendors and manufacturing teams to support prototype fabrication, DFM (Design for Manufacturability), and design iterations.
• Develop jigs, fixtures, and alignment tools to streamline optical assembly and validation processes.
• Support environmental and reliability testing, including thermal cycling, vibration, and mechanical stress validation.
• Create and maintain comprehensive documentation, including BOMs, tolerance analyses, and assembly instructions.
• Collaborate across disciplines to ensure that mechanical design supports electrical, optical, and thermal performance goals in compact, integrated hardware.
