About the role

Responsibilities:
- Plan and execute electrical and optical characterisation of devices and arrays to measure IV behaviour, optical output, uniformity and efficiency.
- Operate manual and semi-automated probe stations to validate device behavior and bridge lab-to-production results.
- Lead accelerated life testing and reliability studies; investigate degradation pathways and failure mechanisms.
- Analyse large probe and test datasets (JMP, MATLAB, Python) to identify yield trends and performance variation.
- Translate data into actionable engineering recommendations and communicate findings to R&D and production teams.
- Develop and refine measurement methods, test strategies and end-of-line verification processes.

Requirements:
- 6+ years in the semiconductor field, with at least 2 years in Device/Product Engineering within a manufacturing environment.
- Strong background in device physics, measurement techniques and hands-on probing/characterisation.
- Proficiency in data analysis tools (JMP, MATLAB or Python) and working with large experimental datasets.
- Experience in reliability testing, failure analysis and tracking long-term stability trends.
- Proactive problem-solving, strong communication skills; stress-testing/thermal characterisation and III–V/optoelectronics experience are advantageous.

Responsibilities

Drive the electrical and optical characterisation of devices and arrays to optimize performance and yield. Lead reliability studies and failure analysis to translate complex datasets into actionable engineering insights.

Requirements

Requires over 6 years of semiconductor experience, including at least 2 years in a Device or Product Engineering role within manufacturing. Must possess strong skills in device physics and analytical tools such as JMP, MATLAB, or Python.
