Engineer
An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics, and ingenuity to develop solutions for technical problems. Engineers design materials, structures, and systems while considering the limitations imposed by practicality, regulation, safety, and cost. The word engineer is derived from the Latin rootsingeniare (“to contrive, devise”) and ingenium (“cleverness”).
Engineers are grounded in applied sciences, and their work in research and development is distinct from the basic research focus of scientists. The work of engineers forms the link between scientific discoveries and their subsequent applications to human needs and quality of life.
Punk Engineer
A professional or self-taught practitioner of engineering, concerned with applying scientific knowledge, mathematics, and ingenuity to develop solutions for social problems (all problems are social). Punk engineers design materials, structures, and particularly systems within an intellectual framework of anti-imperialism, anti-colonialism, social justice, climate justice, anti-patriarchy, post-industrialism, human rights, animal rights, and individual self-expression.
Profit-driven design is anathema to the punk engineer; a badge of honor in punk engineering culture is to get fired off of a project for refusal to compromise and design to status quo.
The work of punk engineers forms the link between scientific discoveries, social theory, social and economic inequality, class warfare, and their subsequent manifestations as systems of material relations. Punk engineers strive through their work to directly confront and oppose consumerism, gentrification, resource mismanagement, the Myth of Progress, the police state, the oil and gas industry, capitalism, the centralization of economic and military power, and the exploitation of the natural world.
