Full Job Description

  • Drive electrical and optical characterisation of devices and arrays, uncovering performance at the smallest scale through detailed measurement and analysis.
  • Get hands-on with manual and semi-automated probe stations, directly validating device behaviour and bridging the gap between lab and production.
  • Capture and interpret key performance indicators including IV behaviour, optical output, uniformity, efficiency, and defectivity.
  • Lead and support accelerated life testing and reliability studies, pushing devices to their limits to understand real-world performance.
  • Investigate degradation pathways and failure mechanisms, turning data into insight on how and why devices evolve over time.
  • Track and interpret long-term stability trends, ensuring robust performance from lab to production scale.
  • Dive deep into raw probes and test datasets using JMP (or similar tools) to extract meaningful patterns from complexity.
  • Identify trends in yield, performance variation, and failure signatures, translating data into actionable engineering insight.
  • Communicate findings clearly from large, complex datasets to influence engineering and process decisions.
  • Help shape the future of testing by developing and refining measurement methods and test strategies.
  • Support continuous verification of what is coming off the production line, ensuring every device meets performance expectations.

    Proven experience of 6+ years in the semiconductor field, including at least 2 years industry experience within a Device Engineering or Product Engineer within a semiconductor manufacturing environment.
  • Experience focused on device performance, characterisation, or electrical/optical optimisation.
  • Strong background in device physics and measurement techniques.
  • Hands-on experience with probing, characterisation, or lab-based testing.
  • Strong understanding of semiconductor device physics.
  • Strong analytical skills using tools such as JMP, MATLAB, or Python
  • Strong problem-solving skills and ability to work with large experimental datasets.
  • Demonstrates a proactive approach by anticipating technical challenges, taking initiative to improve device performance, and driving solutions without waiting for direction.
  • Experience with stress-testing capability and/ or thermal characterisation would be an advantage.
  • Experience with III-V semiconductors and optoelectronic devices would be an advantage but not required.

    £36,057 per year - estimated ?
    • Full time You will be joining a growing team with strong expertise in fabrication and device characterisation & yield, where data-driven insight is used to guide decisions that improve performance. As a team, you will collaborate across R&D and production, driving new characterisation approaches, yield learning, and performance optimisation through to end-of-line testing.,
