Senior Mechanical Engineer

About Us

Spiral Photonics is a well-funded deep-tech startup, building a breakthrough infrared (IR) sensing platform and developing a next-generation imaging and sensing system based on advanced nonlinear optics.

Our technology integrates advanced nonlinear optics, electro-optical engineering, and novel system architectures to unlock a new class of high-performance IR detection capabilities. Our technology builds on more than 15 years of breakthrough academic research from Weizmann Institute and Tel Aviv University and is supported by an experienced leadership and technical team. We are looking for a highly motivated and skilled Senior Optomechanical Engineer to lead the optomechanical design and integration of our next-generation imaging systems.

The Role

As a Senior Optomechanical Engineer, you will be responsible for designing, developing, building, and testing precision optomechanical assemblies for advanced infrared imaging systems. You will work closely with physicists, electronics engineers, and system engineers to translate optical architectures into robust, compact, manufacturable hardware.

The role covers the full development cycle, from optical layout and mechanical concept development to detailed design, prototyping, alignment, testing, and production readiness.

Key Responsibilities

●       Lead the mechanical design and integration of advanced imaging systems.

●       Design precision mechanical structures, optical mounts, alignment mechanisms, and thermal management solutions.

●       Develop mechanical solutions that maintain alignment and stability under thermal, mechanical, and environmental variations.

●       Hands-on assembly, integration, and alignment of imaging systems, including optics, and precision mechanical assemblies.

●       Independently build, modify, and debug Lab prototypes and experimental setups.

●       Perform tolerance analysis, sensitivity analysis, and thermal stability assessments.

●       Lead prototype assembly, optical alignment, experimental validation, and troubleshooting.

●       Define design requirements and verification procedures, and support system characterization and performance optimization.

●       Work with external suppliers and machine shops on precision CNC parts, coatings, surface finishes, and mechanical manufacturing.

●       Drive design-for-manufacturing, reliability, and cost optimization throughout product development.

●       Prepare and maintain detailed CAD models, engineering drawings, BOMs, tolerance specifications, and assembly documentation.

Requirements

●       B.Sc. in Mechanical Engineering, Aerospace Engineering, or a related field (M.Sc is an advantage).

●       5+ years of hands-on experience in optomechanical design and development of precision systems.

●       Strong experience with 3D CAD tools, such as SolidWorks or an equivalent.

●       Proven experience designing precision optomechanical assemblies.

●       Proven hands-on experience building, assembling, and aligning optical systems.

●       Solid understanding of optical alignment, mechanical tolerances, and thermal expansion.

●       Experience with precision machining, CNC manufacturing, and optical component mounting.

●       Practical experience with prototype assembly, lab integration, and experimental troubleshooting.

●       Ability to work independently and collaborate within a multidisciplinary R&D team.

●       Good technical communication skills in English.

Personal Attributes

●       Hands-on, practical, and detail-oriented engineering approach.

●       Strong analytical and problem-solving capabilities.

●       High standards of engineering quality and documentation.

●       Ability to balance performance, stability, manufacturability, and cost.

●       Comfortable working in a fast-paced, multidisciplinary startup environment.
