Your tasks
Shape the test strategy for innovative semiconductor products and take technical ownership from early product development through stable series production.
As a Principal Test Development Engineer, you will play a key role in defining and implementing robust and efficient test solutions for complex semiconductor products. Working closely with international teams across design, product engineering, quality and manufacturing, you will ensure testability from the early design phase and contribute to successful product qualification, industrialisation and ramp-up.
- Develop and implement test strategies and test concepts for ICs at wafer and package level, ensuring testability is considered from the early stages of product design.
- Take technical ownership of test development activities throughout the product lifecycle, from initial concept and qualification to transfer into stable series production.
- Develop, optimise and maintain ATE test software and test hardware, including loadboards, probe cards and related test interfaces.
- Define test requirements and work closely with design and product engineering teams on Design for Test (DFT) concepts.
- Qualify, validate and document test solutions according to defined quality, stability and repeatability criteria.
- Analyse test and production data, investigate test-related issues and drive systematic debugging and root-cause analysis.
- Continuously improve yield, test coverage, test time and overall test efficiency while ensuring reliable product quality.
- Support test transfers, product ramp-ups and production activities at international manufacturing and test locations.
- Act as a technical expert and collaborate closely with colleagues across R&D, Product Engineering, Quality, Operations and Manufacturing.
- Contribute your expertise to technical discussions, design reviews and continuous improvement activities.
Who we are looking for
- Degree or comparable technical qualification in Electronics, Electrical Engineering, Measurement Engineering or a related discipline.
- Several years of professional experience in semiconductor test development, ideally covering IC testing at wafer and package level.
- Strong knowledge of C/C++ and/or Unison and experience in developing and optimising ATE test software.
- Solid understanding of hardware and circuit design, including analogue and digital circuits.
- Good knowledge of Design for Test (DFT) principles and semiconductor test methodologies.
- Hands-on experience with semiconductor ATE; experience with Cohu DiamondX is a strong advantage.
- Experience with optical or optoelectronic devices is an advantage.
- Strong analytical and problem-solving skills, technical ownership and a quality mindset, combined with fluent English, strong communication skills and willingness to travel internationally.
We offer competitive salaries and additional benefits based on your performance, experience and qualification.
The employment is in accordance with the collective salary and wage agreement for employees of the electrical and electronics industry, employment group G (https://www.feei.at/aktuelles/mindestloehne-und-gehaelter-eei/).
We offer a higher compensation depending on your expertise and skills.
