Regular time on-site in Bremen.\nMission\nLead our work on quantum simulation and atomic platforms. The role covers modelling and simulation of quantum many-body systems, model-based calibration of atomic hardware, and optimal control, combining research with a software product that puts those methods into other people's hands.\nResponsibilities\nPillar 1 Simulation and Modelling\nModel and simulate quantum many-body systems, on hardware and in digital twins.\nDevelop and validate models of neutral-atom and trapped-ion platforms against experimental data.\nWork on optimal control and pulse design for atomic systems.\nSuccess Metrics and KPIs: model accuracy against measurement, methods delivered into the product.\nPillar 2 Hardware Engagement\nSupport bring-up and calibration on partner and customer platforms.\nAct as the scientific interface to hardware vendors and research groups running atomic systems.\nTurn what is learned on hardware into product capability.\nAccountability: calibration methods that work on real systems, not only in simulation.\nPillar 3 Research and Teaching\nPublish, and build collaborations with Constructor University faculty and external groups.\nContribute to grant applications, including DFG and EU programmes.\nContribute to course and teaching-lab material if that interests you.\nSuccess Metrics and KPIs: publications, collaborations established, grant applications supported.\nRequirements\nExperience\nPhD in physics, with hands-on experience in neutral atoms, trapped ions or quantum simulation.\nOptimal control, noise modelling or open quantum systems.\nExperience in a leading experimental or theory group.\nTrack record of publication.\nSkills & Competencies\nAble to write the code you need. You do not need to be a software engineer.\nComfortable moving between theory, simulation and real hardware.\nInterest in seeing methods reach users rather than stopping at the paper.\nClear scientific communication.\nEducation & Languages\nPhD in physics or a closely related field.\nFluent English.\nWhat This Role Is (and Is Not)\nThis role IS\nResearch with a product behind it, and users at the end of it.\nA role with genuine publication and collaboration time.\nAccess to hardware and to a university partner.\nThis role is NOT\nA purely academic postdoc.\nA pure software role.\nA role confined to one hardware platform.","description_format":"text","description_chars":2489,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"Advanced
