Photonics Characterisation Engineer

• Design and execute experiments to characterise integrated photonic devices and structures

• Operate optical and photonic laboratory equipment across a range of measurement setups

• Carry out die-level and wafer-level testing

• Analyse experimental data using Python and relevant scientific computing tools

• Develop scripts and workflows to automate data collection and analysis

• Translate experimental requirements into practical, repeatable test methodologies

• Identify measurement issues, investigate unexpected results and troubleshoot experimental setups

• Validate data quality before results are used by wider engineering teams

• Produce clear technical reports, analysis and summaries from experimental work

• Collaborate closely with photonic design, manufacturing and system testing teams

• Support the development and improvement of laboratory processes, test methods and automation

• Take ownership of characterisation tasks and provide realistic timelines for delivery

As you develop in the role, you will be expected to work increasingly independently, building new test methods where required and taking experiments from initial planning through execution, analysis and communication of results.

• An MSc, PhD or equivalent practical experience in Physics, Photonics, Electrical Engineering, Optical Engineering, or a closely related discipline

• A strong understanding of optics and photonics fundamentals

• Hands-on experience designing and running experiments

• Experience working in an optics, photonics or similarly technical laboratory environment

• Experience analysing real-world experimental data using

• Familiarity with scientific Python libraries such as

• A practical understanding of experimental uncertainty, noisy data and measurement quality

• Strong fault-finding and troubleshooting skills

• The ability to work independently while collaborating effectively within a multidisciplinary engineering team

• Strong attention to detail and critical thinking

• Clear written and verbal communication skills

• The ability to present technical results clearly to different audiences

You should be comfortable spending a significant proportion of your time working physically in the laboratory. This is not primarily a theoretical or simulation-focused position.

• Experience working with photonic wafer-level test systems or probe stations

• Experience with integrated photonic devices and their characterisation

• Experience automating experimental setups or measurement equipment using Python

• Familiarity with optical alignment, calibration and measurement techniques

• Experience with free-space optics

• Knowledge of photonic integrated circuit fabrication or semiconductor processes

• Experience developing reusable experimental or data-analysis tools

• Previous experience in an R&D or product development environment

• Experience working in a startup or another environment where processes are still evolving

• Familiarity with Agile ways of working, Jira or similar project-management tools

• Experience communicating the same technical results to both specialist and non-specialist audiences

Relevant backgrounds might include photonics or optics R&D laboratories, integrated photonics research, experimental physics, electrical engineering, semiconductor development or related fields. The common thread is strong experimental judgement and the ability to turn physical measurements into trustworthy engineering conclusions. This is an opportunity to work on genuinely challenging experimental problems in photonics while helping shape how characterisation is carried out as our engineering capability grows. You will have access to advanced laboratory equipment, work closely with multidisciplinary engineering teams and have meaningful ownership over both the experiments you run and how the wider characterisation capability develops.
