As a biomechanical engineer, your duties are to develop and evaluate biomechanical and biomedical technology, such as artificial tissue, prosthetic limbs, or other pieces of technology used to replace body parts or aid patients with physical disabilities. You typically work as part of a larger team of biomechanical engineers and other scientists, such as biologists, chemists, and physicians, to develop new technology and put it into clinical trials. Your responsibilities also include developing documentation for best use protocols and maintenance, designing assessment tools for your technology, and training others on how to install or use it.
