Optical Test & Characterisation Engineer in Berlin

Optical Test & Characterisation Engineer

Location: Berlin, Germany

We are seeking an experienced Optical Test & Characterisation Engineer to design and develop test setups for the measurement and characterisation of advanced optical and photonic components.

This is a hands‑on engineering role focused on optical testing, automated measurement and data analysis within a technically demanding R&D environment.

Key Responsibilities

• Design and develop optical test and characterisation setups for components, modules and systems.
• Develop measurement methods to assess optical performance, accuracy, stability and reliability.
• Work with photodiodes, cameras, spectrometers, lasers and other optical instrumentation.
• Configure and optimise optical measurement systems for repeatable and high-quality test results.
• Develop automated testing and measurement workflows using Python, LabVIEW and/or MATLAB.
• Integrate optical, electronic and software components into automated test platforms.
• Develop data‑acquisition and signal‑processing solutions for optical measurements.
• Analyse test data and identify performance trends, measurement errors and potential system improvements.
• Automate calibration, testing, data collection and reporting processes where appropriate.
• Troubleshoot complex optical, electronic and instrumentation issues.
• Define test procedures, acceptance criteria and characterisation methodologies.
• Validate test setups and ensure measurement results are accurate, repeatable and traceable.
• Work closely with optical, electronics, software and systems engineers during product development.
• Support prototype testing, design verification and technology development activities.
• Document test configurations, measurement procedures, results and technical findings.
• Continuously improve test efficiency, automation and measurement capability.

Requirements

• Degree or equivalent experience in Optical Engineering, Photonics, Physics, Electrical Engineering or a related discipline.
• Several years of experience in optical testing, characterisation or photonic measurement.
• Strong practical experience with optical test equipment, including photodiodes, cameras, spectrometers and lasers.
• Experience developing automated measurement and test systems.
• Programming experience with Python, LabVIEW and/or MATLAB.
• Strong understanding of optical measurement principles and data analysis.
• Experience with calibration, system validation and troubleshooting.
• Strong experimental, analytical and problem‑solving skills.
• Comfortable working in multidisciplinary R&D and engineering environments.

This is an excellent opportunity for an experienced optical test engineer to develop advanced automated measurement systems and play a key role in the characterisation and validation of next‑generation optical and photonic technologies in Berlin.
