Structural Blast Engineer

Thornton Tomasetti applies engineering and scientific principles to solve the world’s challenges. An independent organization of creative thinkers and innovative doers collaborating from offices worldwide, our mission is to bring our clients' ideas to life and, in the process, lay the groundwork for a better, more resilient future. We provide support and opportunities to our employees to achieve their full potential and cultivate a rewarding career. Within our practice, you’ll develop knowledge on how risk-based design brings together security planning, physical security, and electronic security to develop layered protection strategies. You’ll support the development of performance-based solutions—from secure site planning to physical hardening, access control, surveillance, and detection—and how these measures integrate with security operations.

As a Structural Engineer in our Protective Design & Security practice, you will support risk-based engineering and physical security design that strengthens the safety, resilience, and security of buildings and infrastructure. You will apply threat-informed engineering to structural hardening, blast effects, and progressive collapse, helping connect protective measures with architecture, site design, electronic security, and operations across buildings, campuses, and mixed-use environments. With support from your team, you will work in a collaborative, multidisciplinary environment while developing technical, analytical, and project coordination skills.

Support protective design concepts and design studies involving blast effects, progressive collapse, structural hardening, and risk-informed design. Assist with analysis, modeling, and calculation tasks as well as the integration of structural and physical security measures into project designs. Help prepare diagrams, calculations, technical narratives, presentations, and design documentation that communicate protection measures clearly. Coordinate with architects, engineers, planners, and security specialists in a multidisciplinary team environment. Participate in on-site assessments, field surveys, and construction-phase activities. Build familiarity with TT’s culture, services, and collaborative working style while growing your technical and professional skills.

Bachelor’s degree in structural or civil engineering, or a closely related field; master’s degree preferred. Interest in protective design, security, resilience, and hazard-resistant engineering. Strong analytical, written, and verbal communication skills. Familiarity with design, visualization, documentation and computational tools such as Revit, AutoCAD, Rhino/Grasshopper, Adobe Creative Suite, Bluebeam, SAP2000, ETABS, or similar platforms is preferred.
