Kyocera SLD Laser is seeking a highly accomplished MTS Engineer with deep expertise in laser physics, device design, and physics based simulation to drive next generation laser diode technologies from epitaxial concept through device fabrication and experimental validation.

This role is designed for a hands on technical leader and individual contributor who owns solutions end to end—from EPI design inputs and modeling, through device architecture, to test development, characterization, and data correlation. The position supports advanced development and product programs targeting automotive, AR/VR, industrial, biomedical, and display markets.

This is primarily a design and modeling role, with expected hands on engagement in device characterization, correlation, and technical problem solving.

• Architect advanced laser diode structures including MQW active regions, wave guides, DFB/D  cavities, and optical confinement schemes.
• Develop and execute Multiphysics semiconductor laser modeling, epitaxial heterostructure, band structure, and wave guide optical simulation, to guide device architecture, performance tradeoffs, and risk reduction.
• Perform sensitivity and margin analysis for threshold current, slope efficiency, wall plug efficiency, wavelength stability, SMSR, linewidth, polarization, and beam quality.
• Correlate simulation predictions with experimental data and calibrate models accordingly.

• Translate device performance targets into epitaxial structure requirements, including layer thickness, composition, doping, and confinement design.
• Collaborate closely with the epitaxy team to define growth strategies that balance performance, yield, reliability, and manufacturability.
• Lead data driven design of experiments (DOE) to accelerate convergence from concept to robust device designs.

• Collaborate and contribute where possible with Test team on laser diode characterization plans and execution.
• Collaborate with test engineering to develop or refine test set ups, automation, and measurement methodologies.
• Support test engineering…
