Senior Laser Physicist

📍 Israel | Full-Time | Deep-Tech / Photonics / Quantum Sensing / Laser Systems

About Us

Spiral Photonics is a well-funded deep-tech startup, building a breakthrough infrared (IR) sensing platform and developing a next-generation imaging and sensing system based on advanced nonlinear optics.

Our technology integrates advanced nonlinear optics, electro-optical engineering, and novel system architectures to unlock a new class of high-performance IR detection capabilities. Our technology builds on more than 15 years of breakthrough academic research from Weizmann Institute and Tel Aviv University and is supported by an experienced leadership and technical team.

The Role

We are expanding our core photonics team and seeking a Physics/EE Ph.D./M.Sc. with strong hands-on experience in complex optical and laser-cavity design, as well as precision optical systems, to join our physics team. You will design, develop, implement, and optimize a cutting-edge nonlinear coupled-laser optical system. The role requires knowledge of Fourier optics, optical systems, and laser theory, as well as creativity, problem-solving, and a passion for realizing innovative ideas. This is a rare opportunity to design and build the core photonic engine of a next-generation sensing platform from the ground up.

Key Responsibilities

• Design and develop an intracavity laser resonator optimized for nonlinear conversion.
• Perform cavity design, stability analysis, and mode control (Gaussian beam propagation, ABCD modeling).
• Optimize pump beam quality, temporal stability, and pulse-to-pulse energy consistency.
• Lead optical layout design, alignment procedures, and experimental validation.
• Conduct performance characterization (beam quality M², pulse-to-pulse stability, thermal behavior).
• Work closely with system engineers, nonlinear optics specialists, and electronics teams.
• Transition designs from laboratory prototype to robust system architecture.
• Document designs, simulations, and test results.

Requirements

• MSc (or higher) in Physics, Applied Physics, or EE
• 3+ years of hands-on experience in laser development.
• Proven experience designing solid-state laser cavities (e.g., Nd: YAG, or similar).
• Strong understanding of resonator physics and Gaussian beam optics.
• Practical experience in optical alignment and laboratory experimentation.
• Fluency in Phyton/MATLAB.
• Experience in nonlinear optics - strong advantage.
• Ability to work independently in a fast-paced R&D environment.

Preferred Skills

• Experience with intracavity resonator architectures.
• Knowledge of parametric processes (OPO/OPA/upconversion).
• Strong problem-solving mindset and experimental creativity.
• Startup or deep-tech company experience.
