The Role
This is a senior, hands-on software engineering role within an R&D environment, supporting the development of next-generation optoelectronic and semiconductor components. The role is focused on building the software infrastructure used to control instruments, test devices, capture measurement data, and support automated test solutions from early prototype development through to production use.
You will work closely with teams across Chip Design, Wafer Fabrication, Process Engineering, Operations, Quality & Reliability, Verification, and Project Management. Your work will support both early-stage R&D testing and the development of robust, automated test solutions that can later be used in production.
What you will be doing...
Design, develop, and maintain software applications for optical and electronic test systems.
Build software used to control instruments, test devices, collect measurements, and process data.
Develop software infrastructure that supports early prototype testing and automated production test solutions.
Work closely with verification, engineering, and manufacturing teams during new product development.
Contribute to the planning and design of new test setups and measurement workflows.
Develop algorithms and software features that improve automation, efficiency, test coverage, and data quality.
Analyse measurement data to verify test quality and support root-cause investigations.
Release, maintain, and continuously improve software used across development and manufacturing phases.
Ensure software is documented, reliable, maintainable, and aligned with internal standards.
Support knowledge sharing within the team and mentor more junior colleagues when required.
Represent the test software perspective in cross-functional project work when needed.
About You
A Master’s degree in Computer Science, Engineering, Physics, or a related field.
Strong professional experience in software development.
Strong object-oriented programming experience, ideally in C#, C++ or Java.
Experience developing software for test systems, industrial systems, scientific equipment or similar technical environments.
Ability to work close to hardware, instruments, devices, and measurement data.
Experience with Python or MATLAB would be beneficial.
Experience with data analysis, modelling, simulations, or measurement processing would be beneficial.
Experience in semiconductor, electronics, optoelectronics, industrial automation, or manufacturing test environments would be highly relevant.
Nice to haves:
Experience with optical, photonic, or optoelectronic test systems
Experience working with semiconductor devices, lasers, modulators, wafers, chips, or modules.
Experience developing automated production test solutions.
Experience supporting new product introduction from prototype through to production.
Experience leading technical workstreams or representing software/test development in project teams.
