Senior Engineer, Laser Development

Position Overview

Design and develop advanced optoelectronic devices—including FP lasers, DFB lasers, EMLs and external cavity laser modules—to meet performance and product requirements. This role involves building test setups and characterization capabilities aligned with the company’s technology roadmap and integrating these capabilities into in-house manufacturing processes.

Responsibilities

• Design and develop new semiconductor laser–based devices, including creating imaging setups for beam characterization, chip waveguide measurements, and integrating optical systems to achieve stable wavelength and power control; perform thermal, Characterization of electrical, and high-frequency performance testing.
• Design and lead experiments to characterize laser diode components, identify engineering trade-offs, and improve correlation between measurements and simulations, ensuring full integrity and traceability of test and sample data.
• Serve as the strategic technical point of contact for laser device development within our optical engines, working closely with internal teams and external partners; contribute to defining laser integration roadmap.
• Generate timely test reports, including measurement results and detailed analysis.
• Support the full lifecycle of laser components—from initial design and development through procurement, characterization, packaging, and transition to high-volume manufacturing.

Requirements

• Education: Degree or postgraduate degree (Master’s, PhD, or equivalent) in optical engineering, physics, electrical engineering, or related fields; specialization in semiconductor device design and characterization preferred.
• Experience: 5 – 8 years in relevant industries, ideally involving lasers or semiconductor photonic devices; experience with laser simulations and understanding of optical/electrical behavior.
• Technical Knowledge: Familiarity with semiconductor fabrication processes (lithography, etching, deposition, oxidation, implantation) and laser/waveguide simulation tools (e.g., Lumerical, Crosslight).
• Data& Design Skills: Proficiency in data analysis tools (Python, Excel/JMP, Minitab, DOE) and mask layout design software (e.g., Klayout).
• Soft Skills: Strong teamwork and cross-cultural collaboration skills; ability to work independently in a fast-paced environment with strong written and verbal communication.
