Sr. Optomechanical Engineer

We are building the optical layer that the next generation of AI and quantum infrastructure will run on. Our first product is an optical circuit switch built on a spatial light modulator. As Senior Optomechanical Engineer, you will make our optical engine mechanically stable, thermally controlled and repeatable to assemble. You will design the optical mounts, fixtures and enclosures, and build and align the first units yourself. This is a hands-on role at an early-stage company, so you'll own real decisions and help set the technical bar as we grow. If you like hardware that holds alignment after it ships, you'll fit well here.

• Mechanical design. Design optical mounts, fixtures and housings. Choose materials, locking and bonding methods.
• Budgets. Set alignment, tolerance, thermal and vibration budgets with the optics team.
• Thermal design. Control device temperature and remove heat from drive electronics.
• Assembly. Build and align the first assemblies. Compare measured drift and sensitivity with the budget.
• Repeatability. Prove alignment holds after reassembly and environmental exposure. Report distributions, not a single best result.
• Transfer. Deliver BOM, drawings and assembly instructions so a second operator or supplier can repeat the build.
• AI in the workflow. Use AI tools across design, analysis and documentation.
• Cross-team work. Work with optics, electronics and process teams on mechanical, thermal and electrical interfaces.

• Degree in mechanical engineering, physics or a related field. MSc or higher preferred.
• Hands-on experience designing, assembling and debugging free-space optomechanical hardware.
• Tolerance analysis and closure of tolerance budgets on real builds.
• Thermal design and analysis.
• Proficiency with CAD (SolidWorks, Fusion or similar) and FEA tools.
• Experience designing fixtures and running repeat assemblies.
• Clear written and verbal communication, fluent English.
• Comfortable using AI tools across the workflow.

• Fiber arrays, lens arrays or active optical alignment.
• Athermal design and optical bonding.
• Optical switches, beam steering or laser systems.
• Working with machine shops and assembly partners.
• Cleanroom assembly experience.

• Competitive salary commensurate with experience.
• Equity and benefits available, to be agreed upon.
