• Conduct independent and collaborative research on gravitational wave signatures of dark matter and related environments around black holes;
• Develop and validate theoretical and computational models to a standard suitable for robust data interpretation;
• Present results at group meetings, seminars, and international conferences; lead and co-author publications;
• Engage with and support students and the broader project team; contribute to open-science practices (documentation, reproducibility).

You thrive at the interface of theory, computation, and data, and you enjoy collaborating across subfields. Your experience & profile:

• PhD in Physics, Astronomy, or a closely related discipline (at start);
• Strong background in General Relativity / GW astrophysics or cosmological/N-body simulations;
• Demonstrated expertise in scientific computing;
• Track record of research excellence commensurate with career stage (publications, talks).

It is a preference if you additionally have experience with GW source/environment modelling, post-Newtonian/perturbative methods, cosmological simulations, or GW data analysis.

We offer a temporary employment contract for 38 hours per week for a period of 24 months (2 years, full-time), with a possibility of extension subject to funding and performance.

The gross monthly salary, based on 38 hours per week and dependent on relevant experience, ranges between €3,546  to €5,538 (Scale 10). In exceptional cases, if you can demonstrate that you have extensive and relevant experience; and during the selection process it becomes apparent that you are capable of performing the role at a more senior level, classification in scale 11 may be possible. The salary does not include 8% holiday allowance and 8,3% year-end allowance. The UFO profile Postdoctoral researcher 4 (or 3) is applicable. A favourable tax agreement, the ‘30% ruling’, may apply to non-Dutch applicants. This position there will be budget for travel, collaboration visits, computing, access to GRAPPA’s lively scientific environment and the Amsterdam Science Park research ecosystem.
