Postdoctoral and Doctoral Researcher Positions in the Cluster of Excellence "Balance of the Microverse" Friedrich-Schiller-Universität Jena

The Jena School for Microbial Communication (JSMC) is an ambitious Graduate School with over 130 doctoral and postdoctoral scientists. We offer structured, interdisciplinary PhD and career training programs based on top-level fundamental research.

The Cluster of Excellence "Balance of the Microverse" studies the fundamental principles underlying microbial community interactions and functions in diverse habitats, ranging from oceans and groundwater to plants and human hosts. We invite applications for

Postdoctoral and Doctoral Researcher Positions in the Cluster of Excellence "Balance of the Microverse"

We offer: Three Postdoc positions (100% TV-L E13 for 2 years) and 1 PhD position (65%, salary according to German TV-L E13 for 3.5 years) with wet-lab focus to decode microbial balance in a highly collaborative and multidisciplinary research network. The projects starting from July 2026 or at the earliest possible date are embedded in three Cluster research areas:

• SIGNALS: explore how microbes produce, recognize and react to context-dependent signals, and the resulting community dynamics
• STRUCTURES: investigate the compositional and spatial structures of microbial communities and their influence on functions and stability, from local to global scales
• TRANSITIONS: study microbiome stability, resilience, and tipping points, using model systems and clinical data to uncover what drives changes from health to disease

Our Microverse Mission: We integrate insights across ecological and medical fields to enhance our understanding of microbial balance from the molecular to the ecosystem level. We develop tools and detection technologies to shape microbiome dynamics for environmental and human health benefits.

Jena – A Thriving Hub for Microbiology Research: The University of Jena together with the University Hospital and several Leibniz and Max Planck Institutes in Jena, Germany, join forces in the Cluster of Excellence since 2019. The affiliated Jena School for Microbial Communication offers a structured and interdisciplinary postgraduate training program, and career development support.

Your Profile: You have PhD or MSc degree in microbiology, biochemistry, biotechnology, organic chemistry, or a closely related field. You are curious, highly self-motivated and enthusiastic to develop your research project. You work independently and as part of an international team, have excellent English communication skills and are eager to contribute to our Microverse community.

How to Apply: Refer to our individual job offers and apply by May 25.05.2026

Selected applicants will be invited to the JSMC Recruitment Meeting in Jena, Germany (an online interview can be arranged). Awarding decisions will be made shortly thereafter, allowing the projects to start immediately.

The positions will be funded through the Excellence Strategy of the German federal and state governments. The University of Jena and the participating research institutes are equal opportunity employers. Part-time contracts can be discussed. Candidates with severe disabilities will be given preference in the case of equal qualifications and suitability.

Join us in exploring how microbial balance shapes life – and in unlocking its potential for a healthier future.
