Senior Device Product Engineer

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. 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.
