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

What We Need to See

• 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

Ways to Stand Out

• 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
