Job Description The CMX Lab (cmxlab.org) at the Institute for Functional Intelligent Materials studies quantum materials and quantum devices, bridging fundamental discovery and real-world applications. Our work spans correlated and topological electron systems, RF/microwave and terahertz (THz) optoelectronics, and superconducting single-photon sensing. We take devices from concept through to fully characterized. We are seeking a highly skilled experimentalist to lead studies of Far-IR/THz light-matter coupling in strongly correlated 2D systems. The work explores collective electronic behaviour driven by THz radiation, systems pushed far from equilibrium by strong, fast-oscillating AC fields or probed via non-perturbative AC-assisted mechanisms, quantum geometry and interactions in strongly correlated 2D materials probed by bulk photocurrents. The successful candidate will own the full measurement chain from heterostructure assembly and nanoscale device design, through PCB design and THz/Far-IR optics integration into cryogenic environment to hardware automation and low-noise transport and optoelectronic measurements This is a hands-on, full-chain experimental role spanning device fabrication, low-temperature physics, THz/Far-IR optics and high-frequency electronics. Demonstrated, hands-on experience in cryogenics, electron transport measurements and THz/Far-IR optical experimental work is the most important selection criterion. Job Responsibilities Assemble van der Waals heterostructures and design nanoscale devices for THz/Far-IR light-matter coupling experiments in strongly correlated 2D systems Design and operate cryogenic hardware and low-noise measurement setups at millikelvin temperatures, including sample thermalization, wiring, filtering and cryogenic optics integration Design high-frequency PCBs for low-noise signal extraction and readout Design, assemble, and align THz and Far-IR optical setups, including delay lines and quasi-optical elements Analyze and interpret data, prepare manuscripts for publication and present results at group meetings and conferences Develop software for experiment automation, data collection and data analysis Contribute to lab infrastructure and safety and mentor students Job Requirements PhD in physics, electrical engineering, or a closely related field Demonstrated, hands-on experience across the full experimental chain, including experience with cryogenic hardware, low-noise measurement setups and sample thermalization Strong practical background in heterostructure assembly and nanoscale device design and high-frequency device characterization Hands-on experience in designing, assembling and aligning THz and Far-IR optical setups, including delay lines and quasi-optical elements, and experience in designing low-noise measurement-setup assembly A track record of independent experimental work, evidenced by publications, technical reports, or comparable output Excellent problem-solving skills and the ability to drive a project from concept to completion Strong physical background in condensed matter physics, optics and electrodynamics Experience with software development for experiment automation, instrument control, data acquisition and data analysis (e.g. Python, C, C#, .NET) Familiarity with bulk photovoltaic effects and photocurrent-based readout in 2D quantum materials Experience studying systems driven far from equilibrium by strong fields, or non-perturbative AC-assisted probing techniques Experience with high-frequency PCB design tools and device packaging Skills in scientific data acquisition and analysis (e.g. Python) What We Offer Competitive salary commensurate with qualifications and experience, plus benefits in line with NUS policy Support for conference travel, professional development, and career progression Opportunity to contribute to both fundamental science and technology with commercial relevance
