Senior Device Product Engineer

Department: R&D

Employment Type: Full Time

Location: Plymouth

Description

Key Responsibilities

• 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.
  
  

Skills, Knowledge and Expertise

• 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.
