Technical Specialist / Technical Assistant – NMR & Spectroscopy (f/m/d)

Instrument reliability, troubleshooting, and laboratory stewardship

• Perform daily and periodic instrument checks, monitor cryogens where applicable, handle probes and accessories safely, and coordinate preventive maintenance and service visits
• Conduct first-line troubleshooting of sample, software, automation, probe, tuning/matching, temperature-control, and basic hardware issues; escalate appropriately and document corrective actions
• Maintain instrument performance records, SOPs, work instructions, logs, reference samples, consumables, and laboratory inventories
• Contribute to safe laboratory operation, risk assessments, chemical handling practices
• Provide technical support for complementary spectroscopic techniques such as ATR-IR, UV–Vis, and circular dichroism, with training provided where needed

User support and capability development

• Advise scientists, students, and collaborators on sample preparation, experiment choice, realistic turnaround times, and data-quality expectations
• Train authorized users in safe instrument operation, routine acquisition, data handling, and good NMR practice; help maintain concise training materials
• Contribute to workflow improvement, automation, booking and sample-tracking processes, reusable parameter sets, and service documentation
• Collaborate with scientists and technical colleagues on method transfer, feasibility studies, and the introduction of new NMR capabilities

Qualifications and experience

Essential

• Completed vocational training as a chemical or physics laboratory technician, comparable technical qualification, or a Bachelor’s degree/diploma in chemistry, chemical engineering, materials science, physics, or a related discipline
• Substantial hands-on experience with solution-state NMR in an academic, research, or industrial laboratory, including sample handling, instrument operation, and spectral processing
• Practical understanding of locking, shimming, tuning/matching, probe and sample limitations, chemical-shift referencing, and common causes of poor spectral quality
• Ability to work safely, reliably, and independently within defined procedures
• Confident use of laboratory software and structured electronic file management; commitment to accurate, traceable documentation
• Good working knowledge of English and German language

Preferred additional NMR expertise

• Independent setup and optimization of standard 1D and 2D experiments, for example ¹H, ¹³C, ¹⁹F, ³¹P, DEPT/APT, COSY, TOCSY, HSQC, HMBC, NOESY/ROESY, and selective experiments
• Experience with multinuclear NMR, heteronuclear decoupling, variable-temperature experiments, water or solvent suppression, reaction monitoring, or kinetic measurements
• Practical knowledge of quantitative NMR (qNMR), including suitable internal or external standards, relaxation-delay considerations, integration quality, and uncertainty-aware reporting
• Experience with diffusion-ordered spectroscopy (DOSY), mixture analysis, or other advanced experiments relevant to small molecules, polymers, catalysts, or functional materials
• Advanced spectral processing and evaluation using software such as Bruker TopSpin, MestReNova, or comparable platforms, including phasing, baseline correction, referencing, peak picking, integration, and publication-ready export
• Experience with automated sample changers, cryoprobes, temperature-control units, probe changes, instrument performance tests, parameter-set administration, or basic user and queue management
• Ability to recognize common artifacts and diagnose issues systematically
• Experience developing, validating, or transferring fit-for-purpose NMR methods and documenting acceptance criteria in a quality-conscious research environment
• Exposure to solid-state NMR or NMR of challenging sample classes is an additional advantage
