Brown and Caldwell (BC) is seeking a Trenchless Technology Specialist / Design Consultant at the Senior Associate career stage to support planning, design, and construction of trenchless conveyance infrastructure projects. This role is a senior technical position focused on delivery excellence, risk management, and application of best practices for trenchless technologies, including microtunneling, tunneling, horizontal directional drilling (HDD), jack-and-bore, pilot tube methods, and related underground construction techniques.
The Senior Associate will serve as a technical lead and subject matter resource on trenchless and geotechnical aspects of complex water, wastewater, and utility projects. The role emphasizes hands-on technical contribution, mentoring of staff, and participation in business development—without the enterprise-wide leadership, governance, or people-management expectations associated with Managing Principal or National Specialty Leader roles.

- Participate in professional organizations and industry activities related to trenchless technology and underground construction.
