Job summary

Lumina Corp is seeking a Photonics Fabrication and Test Engineer to translate device concepts into repeatable, high-yield fabrication flows. You’ll own end-to-end process development spanning lithography, etch, deposition, and metrology, driving improvements across yield and device performance.

The role involves hands-on cleanroom work, collaboration with design and test teams, and building robust process controls and documentation. A PhD plus 2+ years in photonics fabrication is expected.

Qualifications

• PhD in Physics, Engineering, or equivalent.
• 2+ years hands-on semiconductor/photonics fabrication process experience (industry, lab, or foundry)
• Expert in EBL, ICP-RIE, PECVD, Thermal Evap, SEM
• Experience working with measurement stages, optical and electrical probe alignment, data management.
• Strong fundamentals in process engineering: process control, recipe development, documentation discipline
• Demonstrated ability to troubleshoot complex process issues end-to-end
• Comfortable working in a fast-moving, flexible environment with high ownership

Responsibilities

• Develop, own, and improve end-to-end photonics process flows (process integration, recipe development, yield improvement)
• Run and refine core cleanroom steps (lithography, etch, deposition, lift-off, cleaning, anneals)
• Establish robust process windows, controls, and documentation
• Drive metrology + feedback loops to correlate process to device performance
• Collaborate across fabrication, design, and characterization to improve performance, repeatability, and manufacturability
• Run post-fabrication test and characterisation flows to measure design performance
