Ph.D. student position in Software Maintenance, Evolution, and Operation in the AI era.

We are one of Sweden’s most distinctly profiled institutes of technology, with a focus on IT and innovation for a sustainable future. A key word at Blekinge Institute of Technology (BTH) is closeness – close cooperation with industry and society, and closeness to our students and to our management.
Our closeness to the sea is also very apparent at both campuses, as well as being a comfortable bike ride away from the city and residential areas. BTH stands for quality and new approaches and strives to be recognised as an open, exciting and creative higher education institution.
We develop new knowledge through our research, which often takes place in collaboration with wider society and with a specific application in mind. The research contributes to a sustainable future, directly through our research results as well as indirectly, through our PhD graduates and research-based undergraduate studies. To reach our goals, we need motivated and committed staff who are provided with the conditions to deliver research and education of the highest quality. Work environment and equal opportunities are consistently on the agenda and we strive for continuous improvements. Does this sound like your future?

The Department of Software Engineering consists of about 50 researchers and teachers from 20 countries. Our tradition in software engineering traces back to 1990 when we pioneered Sweden’s first academic education in the software engineering area in cooperation with Ericsson. The department’s research and education environment, SERL Sweden – the Software Engineering Research and Education Lab, has since then expanded into a world-leading research environment in empirical software engineering. The department is responsible for education programs in software engineering from Bachelor to Ph.D. levels.

You are expected to conduct empirical research on technological change in the context of software engineering. The research will investigate the mutual transformation of software evolution and MLOps practices in the context of AI-enabled systems, with a dual focus on how AI techniques can support the maintenance and evolution of software (AI4SE) and how the inclusion of AI components—particularly machine learning models—alters the way software systems evolve (SE4AI).  A strong focus will be on the post-deployment lifecycle of ML components, including drift detection, model decay, retraining triggers, and monitoring strategies, and how these aspects affect the co-evolution of code and data pipelines. The research aims to develop empirical insights and practices that enable more sustainable, observable, and trustworthy evolution of AI-enabled systems

For this position, we are looking for a candidate with a background in software development, data analysis, and artificial intelligence and an interest in Software Evolution, Maintenance and MLOps. The research will be carried out in collaboration with various industry partners.

The key responsibilities include:

• Studying how the usage of AI and ML tools impacts Software Evolution and Maintenance
• Studying how AI-enabled systems are maintained and evolve.
• Publishing research findings in top-tier conferences and journals, contributing to industrially relevant research in software engineering.

Rules and benefits for Ph.D. students in Sweden apply to this position. The Ph.D. student will develop an individual study plan in software engineering together with his/her supervisors. The position may include up to 20% of other services, e.g., teaching at the undergraduate and graduate levels.

To be employed as a Ph.D. student, it is required that the applicant is or will be admitted to postgraduate education.

Eligible for admission to postgraduate education is a person who has completed a degree at an advanced level in a technical, mathematical, or scientific field or who has otherwise acquired knowledge to be able to benefit from postgraduate education in the subject.

Eligibility requirements have to be satisfied at the time of getting enrolled in the studies, not at the time of applying for the position.

In addition to the requirements described in the work description and the eligibility requirements for the position, the following degrees, competencies, and experiences are considered a merit:

• Master or Master of Science degree in software engineering, data science, AI, or computer science.
• Documented experience in professional software development.
• Experience and interest in Artificial Intelligence and Machine Learning development.
• Proficiency in written and oral communication in English.

Place of employment: Karlskrona.

Employment level: 100%.

Commencement: To be agreed.

Duration: Temporary employment for up to 4 years of full-time research. The position may contain up to 20% other services, e.g., teaching, whereby the employment period can be extended to a maximum of 5 years.

Application deadline: June 13, 2025. The deadline has been extended.

Your application should contain the following:

• A statement of your background, knowledge, and experience in the area(s) relevant to the position.
• A CV.
• Certified degree certificates and transcripts that are officially issued by your university; see universityadmissions.se for official recommendations.
• Contact information for two references (reference letters are not required at this point).
• The earliest date you can start to work.
• An appendix with current publications (if applicable).
• A link to your thesis (latest/highest degree).
