Optical & Manufacturing Engineer - IA Glasses Lens Technical Lead

As an Optical & Manufacturing Engineer at Reality Labs, you will own the development and productization of precision optical components, including ophthalmic-grade optics, that are core to next-generation AI and AR glasses.

You will serve as the single point of accountability for optical components, from concept through prototype and validation to high-volume production ramp, working alongside a team tackling radically new concepts driven by the constraints of advanced AI and AR glasses.

You will establish new process and tooling capabilities with supply-chain partners and release product sub-systems that are fully hardened for high-volume manufacturing. We are looking for engineers who work well across disciplines, who move fluidly between big-picture ideas and the critical details that make a technology succeed, and who bring a data-driven track record of taking products from concept to mass production.

Responsibilities

• Own precision optical components from concept through prototype, validation, and high-volume production ramp, as the single point of accountability for the outcome
• Lead external vendor and supply-chain collaborations spanning material selection, tooling, process optimization, metrology, and quality control
• Develop and qualify ophthalmic manufacturing processes and the metrology used to verify optical components, including optical power, surface form, wavefront, and cosmetics
• Define and qualify manufacturing processes and tooling, including precision molds, fixtures, and optical surface generation, to establish new process capability with partners
• Drive mold design and mold flow analysis to optimize tool geometry, gating, and process windows for optical-grade parts
• Develop and qualify high-precision lens cutting processes, including CNC machining, edging, and laser systems at scale
• Troubleshoot optical and mechanical defects and run design of experiments (DOE) for root cause analysis and process improvement
• Develop and integrate novel materials and fabrication processes such as lamination, optical surface generation, coating, casting, and injection molding to enable next-generation optics and displays
• Partner with cross-functional teams to set program priorities and deliver product sub-systems hardened for high-volume manufacturing

Qualifications
