Full Description

Test Characterization Engineer (Photonics & Optoelectronics)

We’re on the lookout for a Test Characterization Engineer to support the development and qualification of photonic and optoelectronic devices.

This is a hands-on lab role combining optical/electrical measurements, test system development, data analysis, and close collaboration with device design teams from early prototyping through qualification.

You’ll work in a high-performing R&D environment alongside photonic, electronic, and process engineers, helping evaluate new device concepts through rigorous characterization and turning measurement results into clear, actionable feedback.

What you’ll be doing

• Develop and execute test and characterization plans for photonic/optoelectronic devices
• Perform optical, electrical, and opto-electrical measurements across a range of lab setups
• Run fiber-based characterization (e.g., insertion loss, coupling efficiency, fiber alignment, mode behaviour)

Design, build, and maintain measurement systems: probe stations, optical benches, free-space optics setups, optomechanical assemblies Integrate optical components using optomechanical techniques (stages, mounts, alignment systems) for stable, repeatable measurements Collaborate with photonic/electronic/process teams to define test requirements and review results Analyse measurement data, document outcomes, and provide recommendations to support design iteration and qualification Create and improve test procedures, using existing infrastructure and developing new setups where needed Maintain lab equipment, ensure repeatability, and follow lab safety and best practices

What we’re looking for

• Familiarity with free-space optics, optical alignment, and optomechanical integration
• Experience with optical and high-speed electrical measurement techniques

Strong practical lab capability: building, troubleshooting, and refining measurement setups Data analysis and test automation skills (e.g., Python, MATLAB, or C; instrument control/scripting) High attention to measurement quality, repeatability, and detail Clear technical documentation and communication skills

Qualifications

• BSc or MSc in Electrical Engineering, Photonics, Physics, or related discipline
• Hands-on experience in photonic and/or optoelectronic device testing
• Strong background in optical testing including fiber characterization and optical coupling techniques
