Location: Jerusalem

Type: Full-time

Reports To: Optics and System Team Manager

Company Overview We are an innovative growth company in the field of silicon photonics packaging, solving one of the key challenges in enabling next-generation co-packaged optics solutions for AI infrastructure, Data Centers, and High-Performance Computing. Our multidisciplinary team combines optics and packaging expertise to bring cutting-edge technologies from concept to scalable production.

Role Overview We are seeking a hands-on, creative, and analytical Experimental Scientist to join our multidisciplinary R&D team. The ideal candidate thrives in a dynamic environment, enjoys solving complex problems, and is passionate about transforming experimental insights into real-world technological advances. This role requires deep scientific curiosity, precision, and a can-do approach to experimental design — along with strong collaborative skills and the ability to mobilize people and teams toward shared objectives in a metrics-driven environment.

What You Will Be Doing

• Design, plan, and execute complex optical and physical experiments to validate and optimize novel packaging processes and photonic assemblies.
• Conduct system diagnostics, troubleshooting, and problem-solving: tasks include simulations, root-cause analysis, mitigation plans, implementing robust system calibration methods, and product transfer to manufacturing.
• Develop and implement experimental setups, measurement techniques, and data analysis methods.
• Collaborate closely with engineers and scientists across optics, materials, and semiconductor domains to translate findings into design and process improvements.
• Lead or coordinate small cross-functional task forces to address key R&D and process challenges.
• Analyze data, define KPIs, and track progress in a metrics-driven environment to ensure measurable improvements.
• Operate and maintain laboratory instruments and optical test systems.
• Document experimental procedures, results, and conclusions clearly and systematically.
• Work effectively under tight deadlines in a fast-evolving startup environment.

What We Need to See

• 2+ years of hands-on experience in complex problem solving and system engineering, preferably in optics, photonics, or semiconductor-related fields.
• Advanced degree — M.Sc. or Ph.D. in Physics or related discipline (Optics, Applied Physics).
• Strong experimental and analytical skills with a systematic, methodical approach.
• Proven experience designing, conducting, simulating and interpreting complex physical or optical experiments.
• Exceptional interpersonal and collaborative skills, with the ability to influence, motivate, and align cross-functional teams.
• Demonstrated experience working effectively in a metrics and results-oriented environment.
• Excellent problem-solving abilities and a can-do, solution-oriented mindset.
• Strong communication and documentation skills.
• Comfort working in a multidisciplinary and dynamic environment under tight timelines.

Ways to Stand Out

• Hands-on experience with fiber optics, optical coupling, or photonic packaging.
• Familiarity with semiconductor processes, precision alignment, or micro-optical assembly.
• Proven ability to drive team performance using data, metrics, and well-defined goals.
• Experience in startups or fast-paced innovation environments.
• Practical experience with optical simulation, automation, or data analysis tools (e.g., Zemax, MATLAB, Python).
