Duties

The Materials and Structural Systems Division in the Engineering Laboratory conducts experimental research on an array of topics focused on structural systems and materials performance composing US buildings and infrastructure. Research projects within the Division focus on the prediction of the performance of conventional and innovative materials, components, and structural systems throughout the service life by developing a fundamental understanding of the performance properties and the degradation mechanisms when exposed to intended (real world) or accelerated (laboratory) loading environments. Material systems being evaluated include polymers exposed to environmental stressors, including ultraviolet light. Concrete development efforts include measurement methods for 3D printing of cement-based materials. Some of the experimental work includes structural testing of large steel, 3D printed concrete, or reinforced concrete specimens. Ongoing structural engineering research includes innovative beam-column connections for enhanced robustness of precast concrete structures, and assessment criteria for structural components considering loading history. If selected at the II level, you will: Participate as a creative member of an engineering or technology team. Under the supervision of senior ZT staff, perform well-defined tasks related to the preparation and construction of structural concrete/steel test specimens, prepare concrete specimens for materials testing, and install various sensors on testing specimens. Assist senior ZT staff with troubleshooting, to include assisting with the development, enhancement, and corrections of systems, technical equipment, instruments, and/or software. Under supervisor guidance, carry out smaller parts of experimental testing. Follow health, safety, and environment guidelines and procedures and perform work that improves the safety of the work environment. Provide engineering support on assigned projects through the application of professional knowledge and skill in engineering practices, processes, and techniques. If selected at the III level, you will: Participate as a creative member of an engineering or technology team. Perform tasks related to the preparation and construction of structural concrete test specimens, including acquisition of materials and construction of formwork, application of sensors on reinforcement, and planning for concrete delivery and casting of specimens. Perform troubleshooting that includes assisting with the development, enhancement, and corrections of systems, technical equipment, instruments, and/or software. Under supervisor guidance, carry out experimental testing based on objectives, priorities, and deadlines. Follow health, safety, and environment guidelines and procedures and perform work that improves the safety of the work environment. Provide engineering support on assigned projects through the application of professional knowledge and skill in engineering practices, processes, and techniques. The ideal candidate will have experience in the following: electronics repairs, soldering, field and laboratory concrete testing, computer-aided design and drafting software (AutoCAD, SolidWorks), familiarity with Labview for collecting data using NI DAQ systems, Python, or other programming language, for analyzing experimental data. Any previous experience in using power tools and equipment during construction activities, such as: concrete saws, drills, coring equipment, jackhammers, forklifts, skid steers, overhead cranes, etc.
