The study of quantum hybrid systems is an emergent field of quantum optics with many potential applications in e.g. quantum communication or in the search for quantum behavior of macroscopic objects. In this poster we present our progress towards a new hybrid quantum system experiment, which aims at coupling ultracold atoms to micromechanical oscillators. In a first experiment we will couple a high-Q micromechanical membrane located inside a fiber fabry-perot cavity to a Rubidium BEC via an optical lattice. As a promising starting point to reach the ground state of the oscillator the fiber cavity - membrane setup will be cooled to temperatures around 30mK inside a dilution cryostat. On the long-term also short range (e.g. magnetic) interactions can be realized by creating Rubidium BEC inside the cryostat.
