Physicist (f/m/x) - Modelling and Simulation of quantum-opto-mechanical sensors

At the DLR Institute of Quantum Technologies in Ulm, we develop precision instruments for space applications based on quantum technologies and bring them to prototype maturity together with industry. In addition, we are driving forward the transfer to aeronautics, digitalisation, energy, security and transport. We have an interdisciplinary approach: Theoretical basic research and experimental tests meet engineering implementation.

What to Expect

The Quantum Metrology department develops highly precise optical and opto-electronic measurement systems for applications in navigation, Earth observation and scientific missions. Laser-based technologies such as interferometric sensors, optical references and fiber-optic systems enable measurements with extremely high precision.

In this position you will contribute to the development of novel laser‑interferometric acceleration sensors for next‑generation inertial navigation systems. These sensors enable reliable navigation in environments where GPS signals are unavailable or disturbed. Your work will focus on the experimental implementation, characterization and miniaturization of quantum‑optical metrology systems as well as the development of interferometric and laser‑based measurement techniques.

Your tasks

• You carry out theoretical modelling and simulation of quantum‑optomechanical systems, sensors, and inertial sensing.
• You analyse noise sources and gravitational signals — at the interface between theory and experiment.
• You will participate in the relevant experiments.
• You will interpret and analyze the acquired data.
• You evaluate sensor systems, measurements, and theoretical models, and derive optimisation strategies for the design, modelling, and simulation of experimental setups.

Your profile

• Completed scientific university degree (Master / Diploma Uni) in natural sciences (e.g. physics) or engineering (e.g. from the fields of aerospace engineering, mechatronics, electrical engineering) or other degree programmes relevant to the position
• Solid theoretical knowledge in at least one of the following areas: optomechanics/cavity optomechanics, gravitational physics (Newtonian/post‑Newtonian), or noise processes and quantum measurement theory
• Proficiency in numerical methods and programming (e.g., Python, MATLAB), particularly in the context of physical modelling and simulation
• Experience or strong interest in laser interferometry, precision measurement technology, or inertial sensor technology/gravimetry, e.g., gained through studies or a thesis
• Interest in experimental work and willingness to actively participate in measurements, sensor characterization, and prototype development
• Ability to clearly communicate theoretical concepts to experimental teams in photonics and electronics
• Independent and structured work style, as well as a willingness to engage in interdisciplinary collaboration
