Job description

Hours40 hr.Salary indicationSalary gross/monthly
based on full-time€ 2,901 – € 3,707Deadline11 Aug 2025The challengeThis PhD research focuses on the advanced design and analysis of kinematic couplings-a key technology for achieving passive, high-precision, and deterministic alignment between precision components. Unlike active alignment methods that rely on actuators and sensors, kinematic couplings enable self-alignment purely through geometry and contact mechanics, offering a fast, robust, and repeatable solution for high-tech applications.Although the concept of kinematic couplings has existed for decades, the underlying physical phenomena remain poorly understood. In particular, the effects of friction, compliance, and contamination on alignment repeatability introduce uncertainties that limit their predictability and broader application.You will investigate the underlying mechanical principles-including contact stiffness, constraint geometry, and material interactions, in particular friction-to develop novel coupling designs optimized for increased repeatability, thermal stability, and load-bearing capacity. These designs are critical in fields such as:

  • Optical component alignment
  • High-precision metrology instruments
  • Wafer bonding in semiconductor manufacturing
  • Engine docking assemblies
  • Medical diagnostic and imaging systems

A key aspect of this research is addressing fundamental engineering challenges that currently limit the adoption of kinematic couplings, including:

  • Initial alignment sensitivity during assembly or docking
  • Thermal fluctuations and their impact on positional stability
  • Loadability and robustness under dynamic or off-axis forces

You will combine analytical modeling, finite element simulations, and experimental validation to explore new coupling topologies and materials. The goal is to push the boundaries of passive alignment technologies and enable their integration into next-generation precision systems.As a member of the Precision Engineering Laboratory, you will become part of a collaborative team of PhD researchers working in a dynamic and supportive environment. You will have the opportunity to present your research at leading international scientific conferences, helping you grow your academic profile and expand your professional network. This project is closely connected to and funded by the Dutch precision engineering community, offering a unique chance to contribute directly to innovations in high-tech industry.Your profile

  • You are an enthusiastic and highly motivated researcher with a strong interest in Precision Engineering.
  • You hold, or are about to obtain, a Master’s degree in Mechanical Engineering or a closely related field.
  • You have excellent command of both written and spoken English.
  • You possess strong skills in (non-linear) mechanical modeling, system dynamics, tribology, and mechanical design.
  • You have practical experience working in laboratory environments, including setting up experiments, operating precision instruments, and analyzing experimental data.
  • You have a high degree of responsibility and independence, able to collaborate with colleagues, researchers, and other university staff.

Our offer

  • A dynamic and international environment, combining the benefits of academic research with a topic of high industrial relevance;
  • A full-time position for four years, with a qualifier in the first year, and the flexibility to work (partially) from home.
  • Excellent working conditions in an exciting scientific environment, and a green and lively campus;
  • A professional and personal development program within Graduate School Twente;
  • Your salary and associated conditions are in accordance with the collective labour agreement for Dutch universities (CAO-NU).
  • You will receive a gross monthly salary ranging from € 2.901,- (first year) to € 3.707,- (fourth year);
  • There are excellent benefits including a holiday allowance of 8% of the gross annual salary, an end-of-year bonus of 8.3%, and a solid pension scheme.
  • A minimum of 232 leave hours in case of full-time employment based on a formal workweek of 38 hours. A full-time employment in practice means 40 hours a week, therefore resulting in 96 extra leave hours on an annual basis.
  • Free access to sports facilities on campus.
  • A family-friendly institution that offers parental leave (both paid and unpaid).

Building on the Dutch design principles legacy of van den Hoek, Koster, and Soemers, we specialize in flexure-based design for frictionless, repeatable motion. Interdisciplinary collaborations-with control, materials, and tribology experts-enable the creation of high-quality technology demonstrators. Strong ties to Dutch industry ensure our research is both scientifically rigorous and industrially relevant.Our well-equipped lab is a hands-on environment where scientific rigor meets engineering creativity. We don’t just build systems that work-we strive to understand why they work. With high-precision tools and a strong focus on physical insight, the lab serves as a playground for researchers driven by curiosity and a passion for precision.About the organisationThe Faculty of Engineering Technology (ET) engages in education and research of Mechanical Engineering, Civil Engineering and Industrial Design Engineering. We enable society and industry to innovate and create value using efficient, solid and sustainable technology. We are part of a ‘people-first’ university of technology, taking our place as an internationally leading center for smart production, processes and devices in five domains: Health Technology, Maintenance, Smart Regions, Smart Industry and Sustainable Resources. Our faculty is home to about 2,900 Bachelor’s and Master’s students, 550 employees and 150 PhD candidates. Our educational and research programmes are closely connected with UT research institutes Mesa+ Institute, TechMed Center and Digital Society Institute.Want to know moreJong, J.J. de (Jan)
