Application Engineer

Location: Jerusalem

Type: Full-time

Reports To: Integration & Validation Team Lead

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

As an Integration & Validation Engineer, you will play a key role in the characterization, validation, and continuous improvement of advanced photonic products and assembly processes. You will work closely with R&D, process, and manufacturing teams to investigate product performance, understand failure mechanisms, develop test methodologies, and improve measurement capabilities.

This role combines hands-on laboratory work, optical characterization, data-driven analysis, automation development, and root-cause investigation. We are looking for an engineer who enjoys both working with their hands and applying analytical thinking to solve complex technical challenges.

What You Will Be Doing

• Perform optical characterization and validation of photonic devices, fiber assemblies, and packaged products
• Operate and improve automated scanning and measurement stations
• Analyze optical performance data and investigate deviations from design expectations
• Design and execute experiments to better understand product behavior, process sensitivities, and failure mechanisms
• Lead root-cause investigations for product failures, performance variations, and unexpected measurement results
• Develop automated analysis tools and laboratory utilities using Python
• Collaborate with R&D, process, mechanical, optics, and manufacturing teams to support product development and qualification
• Create and maintain test procedures, validation protocols, technical reports, and engineering documentation
• Identify opportunities to improve measurement methods, throughput, accuracy, and data quality
• Work closely with global customers, suppliers, and development partners across multiple countries and time zones
• Support project execution in a dynamic environment while managing multiple priorities and deadlines
  
  

• B.Sc. in Materials Science, Chemistry, Chemical Engineering, Physics, or a related technical field
• 1–5 years of experience in engineering, validation, test development, optics, photonics, or related fields
• Strong analytical and problem-solving skills with a structured approach to root-cause analysis
• Hands-on laboratory experience with optical, electro-optical, or precision measurement systems
• Experience analyzing complex datasets and drawing meaningful technical conclusions
• Proficiency in Python for data analysis, automation, or test development
• Strong technical communication skills in English (written and verbal)
• Ability to work effectively under pressure and manage multiple priorities in a fast-paced environment
• Experience collaborating with cross-functional teams, customers, and suppliers across multiple countries worldwide
• Travel – Up to 1 week/month
  
  

• Experience with silicon photonics, fiber optics, optical packaging, or optical communications
• Familiarity with automated test systems, motion control, machine vision, or laboratory automation
• Experience with Design of Experiments (DOE) and statistical data analysis
• Knowledge of image processing, data science, or machine learning techniques
• Experience developing software tools for engineering or laboratory environments
• Strong understanding of optical measurements such as insertion loss, return loss, alignment, and polarization effects
• Experience working in multidisciplinary R&D environments and transitioning products from development to manufacturing
• Demonstrated ability to independently investigate complex technical problems and develop practical solutions
